Introduction

Concept

Landscan WCA (Windows Control & Analyse) is a powerful system meeting the thermal information needs of engineers and managers, from Process Control through to Quality Assurance.

The system can be integrated into the plant wide control and management systems at every level.

Landscan WCA builds upon the power, scalability and manageability of the Microsoft Windows™ NT/2000/XP operating system by providing the reliability and advanced capabilities of high-end thermal information processing, multi-format data display options and extensive database storage facilities.

System Architecture There are four key components to the Landscan WCA system.

Landscan Head

This compact instrument with very high accuracy, and repeatability, outputs the linescanner thermal information as fast analog signals.

Currently there are two versions available, these are designated the LS Scanner and the LSP Scanner – each are available in a variety of wavelength and temperature ranges.

LPU/LSC Processor

LAND Instruments International Ltd. LANDSCAN WCA Introduction • 11

These processors are high-speed input output devices designed for the Landscan system, contained within a single unit. All analog outputs and signal inputs are fed into the unit, RS232 communication is also provided at this level. Thermal data is delivered to the Landscan WCA Data Server via Ethernet communications.

The LPU_2E Processor has been replaced by a new family of Landscan Control Processors:

LS Control Rack

This is a 19in rack mounted unit, it provides a hardware and software interface for the LSP and LS range of Landscan heads.

Landscan Control Compact

This economic back-of-panel mounted signal processor units for single head applications.

Landscan Control Batch

This is a 19in rack mounted unit based on the design of the Landscan Control Rack. It includes new more powerful processing capabilities and provides a hardware and software interface for the LSP and LS range of Landscan heads.

Each of the new Landscan Control Processors can be configured for up to:

Input Type No. of Channels Specification Digital 8 Closed contact with respect to isolated 24V,

active high

Analog 8 Differential, milliamp or voltage - link selectable. 0 to 1/2/5/10V range, scaling span and offset - independently software selectable

Output Type No. of Channels Specification Digital 12 Voltage-free relay outputs

Analog 12 0 to 20mA / 4 to 20mA - independently software selectable

Landscan WCA Data Server


This performs data management activities, databasing the thermal data and providing it in various formats to others within the organisation. The computer runs the Landscan WCA Data Server software, which collects the data from the LPU/LSC processors and processes it. It will provide displays for both real time and historical products.

More Information

Landscan WCA Client Display PC

This computer runs the Landscan WCA Client Display software, which provides displays for both real time and historical products. The product data is sourced from a Landscan WCA Data Server. The Client PC will require Ethernet communications to the Landscan WCA Data Server.

System Benefits

System Scalability Building upon the scalability of the Windows NT/2000/XP operating systems, the Landscan WCA system is completely scalable:

Simplest Landscan WCA System:

• 1 Landscan Head

• 1 LPU/LSC Processor

• Connected via a single Ethernet connection and switching hub to Landscan WCA Data Server.

Distributed Landscan WCA System:

• Up to 8 Landscan Heads

• Up to 8 LPU/LSC Processors, with inputs for plant speed and fixed thermometry signals

• Connected via a switching hub to a Landscan WCA Data Server, which can contain several months worth of data which is available online to satellite client displays.

• Communication to Plant Supervisory Control Computers

• Receiving Product Definition Information via PDI Messaging


• Passing statistical thermal summaries for each product to the plant database.

Plant wide integration The system can be integrated into the plant control and supervisory systems at every level, via analog 4-20mA zones and alarm contact signals to the PLC's, and via digital communications across either slow speed RS232 from the LPU/LSC or high speed Ethernet from the data server.

System security The three component parts of the system are arranged in a hierarchy, with the scanner at the bottom and the data server at the top. All the lower components of the system perform independently from the unit above.

By separating the digital-processing element from the Landscan Head, the quantity of equipment exposed, in hot processes, to hostile environments is kept to a minimum.

The LPU/LSC Processor is highly reliable and is ideally suited for incorporation into Process Control loops with PLC's. The unit will continue to operate independently regardless of any activities at the Landscan WCA Data Server level, for example if the Data Server is powered off. Therefore the low-level process control feedback loop is secure from the rest of the system.

The use of a network hub further isolates all the individual networked components of the system from each other.

Bringing together all the infrared thermometry information The Landscan WCA based system can acquire, process, display and store information from the Landscan Heads, and all the other Land fixed thermometer products (using analog inputs). This allows integration of all the thermal information into one common system, for display and storage.


Information Database Raw data, from connected Landscan Heads and Land fixed thermometers, is brought together and packaged as products. All databasing and data displays are orientated around the products processed rather than the sensors, making the system data more accessible to the user.

The Landscan WCA Data Server is responsible for storing the data for a product in files on the hard disk; each product is stored as an independent file. These can then be retrieved by either the data server, client display or offline analysis database.

The multi-user capabilities are provided through the Landscan WCA Data Server software.

Information Required In order to provide accurate information relating to the lengths of products and product naming the system requires additional information to the thermometry data regarding the product identity and speed.

The data server software has algorithms to track products through the process; in order to do it requires real time product information from the plant computer systems.

What information and to whom The system has been designed to facilitate the provision of timely and accurate information in an appropriate form to all the diverse end users who need the information. These users encompass the following: -

Process control The requirement is for fast thermal information, typically with the LPU/LSCs Control Zones configured to match the control sectors of each cooling or heating element across the process.

The Control Zones feature within the LPU/LSC provides up to 14 zones, which can be configured to provide the precise max/min/peak temperature of the product corresponding to each control element. Alarms can be independently configured to particular thresholds on each zone.


This information can be output to a PLC using 4-20mA zone signals or contact signals for the alarms.

In situations where there is product 'noise' for example scale or water, which may occasionally invalidate the infrared data, then there is a signal-conditioning algorithm to minimize these distortions of the true product temperature.

The LPU/LSC can operate independently from the rest of the Landscan WCA System, and is thus suitable for incorporation into the process control feedback loop. .

Process monitoring The Landscan WCA System can provide useful information to the process operators as to the real time behaviour of the process.

The client display software provides real time displays of the product's thermal data in a variety of different display formats, from simple profiles, through two-dimensional thermal maps to three dimensional waterfall displays. All the control zone data can also be displayed.

The software can be run in a central location or on a number of remote networked installations, so that the information can be visualised in all the control rooms along with other real time displays such as video.

Various simplified displays can be used to indicate the in/out of manufacturing tolerance areas of the products, bringing problems to the attention of the engineers. (These simplified displays are the Alarms and 2D relative maps).

The displays at each computer can be tailored to present the information to best benefit the engineers at that location.

Process investigation In the event of a problem occurring within the process, the displays can be used to identify the problem if it is thermally related. The thermal displays can highlight problems that the eye cannot see. Thermal irregularities usually indicate process control problems, for example a blocked cooling jet.


If the problem has passed; previous product data can quickly be requested via the database facilities for display and review. Color printouts can also be made for later diagnosis.

Using the cursor tool, the thermal information can be examined in detail, so the precise positions of the problems can be found.

Process development Process development usually involves the modelling of the process behaviour, in order to improve process control. The database of previous product data provides an ideal environment for cross-referencing the effects of changing control parameters employed during production. Statistical data can be fed directly into existing process mathematical models.

The Landscan WCA Offline Analysis software allows users to analyse these data files on a computer separate to the data server that is collecting the actual scanner data.

Quality assurance Thermal records provide an invaluable accurate record of the quality of a product and can form a central component of an ISO 9000 series quality assurance system. The records can either be immensely detailed with data resolved to very small areas of the product, or can be simple statistical summaries for the whole product. Since our sensors are traceable to NAMAS (National Measurement Accreditation Services) calibration standards, then the data integrity is ideal for a quality assurance function.

Plant wide information management systems Most plants have a plant wide Information System, in which data is logged from various sensors and systems. This simplified statistical data is then available across the whole organisation. The specific thermal data requirements of the system can be met with data processing and communications designed to meet the exact requirements of the organisation.

Landscan WCA requirements The system minimum hardware and software requirements to run the demonstration, offline analysis, data server and client display are detailed in the readme.txt file.


The benefits of using a switching hub From a technical point of view, Ethernet switching technology greatly boosts the total bandwidth of a LAN network. The benefits to the Landscan WCA System are that data from the LPU/LSC processors can be transferred to the data server in real time.

Most network systems, pass files or messages across the network intermittently, there is no requirement for instant transmission. The Landscan system transfers linescanner data messages from the LPU/LSC processors to the Data Server in real time (every 40ms). In a situation where there is other traffic causing collisions or noise resulting in re-transmissions then the effective bandwidth is greatly reduced. This has the effect of reducing the real time capabilities of the system.

Other benefits are that each connection between the components of the system is isolated; hence localised faults will not impact upon the whole system.

Specification The major limitation to the specification of the system is the processing power of the Landscan WCA Data Server. The current system limits are:

• 8 scanners at 100Hz 1000 samples. ( suitable Dual CPU Workstation may be necessary )

• Maximum database size is limited to the free hard disk space.

• Total number of simultaneous Landscan WCA Display Clients is limited by the purchased licenses applied.

• Total number of Live ActiveX connections is limited by the purchased licenses applied.

These limits are under constant review. You should contact Land to discuss your requirements.

18 • Software Installation LAND Instruments International Ltd. LANDSCAN WCA

Software Installation

Installation Types There are four types of Landscan WCA Installation; each type of installation is performed from the same software CD.

Landscan WCA Demonstration This allows the user 90 days to evaluate the functionality of the software using pre-installed data files of example applications.

The demonstration software requires no external network connections.

Landscan WCA Data Server This software installation will create the main data acquisition and storage computer with the capability to provide data to client displays in real time.

Network Installation Ensure that the TCP/IP protocol is installed on the computer. Use Windows Help (accessed from the start menu) to provide details on how this is done.

If you are not using the DHCP method of TCP/IP addressing you should contact your network administrator for the IP address of the computer on the network. Unless you have specific reasons for using a different subnet mask value 255.255.0.0 is recommended. After configuring the network you must reboot the computer.

LAND Instruments International Ltd. LANDSCAN WCA Software Installation • 19

If you have configured the IP address manually check the network connectivity by using PING.EXE which is part of the Windows Utilities. At the Start Menu, Run Command – type CMD.

Type ping <IP address> where the <IP address> is the IP address of the connected LPU/LSC. Using <IP address> 10.1.10.107 as an example, a response should be returned of the following or similar type: -

Reply 10.1.10.107: bytes=32 TTL=64

If this has failed then the reply will be Request timed out. From a Data Server you must be able to ping to each LPU/LSC to obtain scan data.

The recommended transfer rates are:

Data Server to LPU/LSC 100Mbps

Data Server to Client PC 100Mbps

LAND recommends the use of a network switch in such an applications

For large numbers of LSC processors in a system a Gigabit switching hub may be necessary.

More detailed information on networking to the LPU/LSC can be found in the relevant processor Installation Guide, User Guide, Service Manual.

Landscan WCA Client Display This software installation will allow a computer to log onto a Data Server computer to view data in real time and change the configuration.

To discuss your changing requirements you should contact your local LAND Instruments Sales Representative or LAND Instruments International Inc.


Landscan WCA Start The installation will have created a new folder in the program menu called Landscan for Windows NT. This allows you to start the WCA software. If the install CD is in the CD-ROM drive you can review the electronic manuals or the Landscan WCA training course.

At the install time the option was available to create an icon on the desktop to start the Landscan WCA software. If this option was selected it will be as follows:

Double click on this icon to start the installed Landscan WCA software. If the installation is a Data Server installation and this is not a successful upgrade of a previous installation then on start-up the user will be prompted to input:

• The number of connected LPU/LSC(s)

• The IP address of each of the connected LPU/LSC(s).

The user does this using the following dialog:


The software will start and can now be used as described in basic operation.

Processor Setup The LPU/LSC must have its network setup and configured to correspond to the configuration on the Landscan WCA Data Server. It is necessary to ensure the following:

• LPU/LSC IP address is correctly configured.

• IP subnet mask settings on the Landscan WCA Data Server and the LPU/LSC must match.

More detailed information on networking to the LPU/LSC can be found in the relevant processor Installation Guide, User Guide, Service Manual.


Changing the number of connected LPU/LSC(s) Only relevant for a Landscan WCA Data Server.

The maximum number of LPU/LSCs that a Landscan WCA Data Server can connect to is limited by the license. However it is possible to connect to up to and including that number. To change the number of connected LPU/LSC(s), enter the Configure - System Menu and the Process Tab.

Changing the LPU/LSC IP Addresses Only relevant for a Landscan WCA Data Server.

When the Landscan WCA Software is installed, and licensed, default IP addresses are loaded, these will need to be reviewed and changed to meet the specific system requirements. To change the IP addresses select the Configure -System menu and then the Equipment Tab. Next enter the required IP addresses, and uncheck the “Take Unit Offline” box associated with that IP address and select OK.

The software will now attempt to connect to the LPU/LSC at the selected IP addresses.

Connect a Client Display to Data Server Only relevant for a Landscan Client PC.

When installing a client display it is necessary to tell the software which data server to retrieve the data from, there must be a data server installed on the same network as the Client PC. This computer has its own unique computer name (which can, for example, be seen in the Windows NT logon dialog box) which should be entered to enter to complete the client display installation.

Note the computer name, select the configure menu and servers option of the client display. The machine names dialog given below is displayed.


Enter the name of the data server computer in the Data Server Machine field and press the OK button.

System Status Display The system status display is displayed at system start or via the Diagnostics menu.

LAND Instruments International Ltd. LANDSCAN WCA Basic Operation • 35

A full description of the System Status display is provided in Diagnostics - System Status.

Status A further indication of the health of the system is given in the status bar. It is possible to enable/disable the status bar from the view menu. If displayed, a description of the particular function is given in the bottom left hand corner and a series of icons are used, at the bottom right corner, show the status of various functions.

The status icons represent the following:


In all cases when a status icon is showing red to indicate a fault the event log will contain an associated event.

Communications Status


Indicator Color Communications Status

Brown Landscan WCA Server Socket is listening with no connection

Yellow Landscan WCA Server has an established connection to a client.

Flashing Green Landscan WCA Server Socket is in the process of receiving or transmitting data

Red Landscan WCA Server Socket has received invalid data.

System Displays

What to expect during software start up The system status dialogue is displayed when the system is starting.

At this time the activity indicator on the system status display, is used to inform the user of the current event taking place within the start-up routine, text messages are displayed next to this indicator..

When the Data Server connects to each LPU/LSC it counts through the 11 stages of each connection. These are displayed as:


If the Landscan WCA software is being started for the first time after upgrade then it may be necessary to upgrade any data files stored on the system. This may take some minutes to complete and the % completed is displayed as follows:

When Landscan WCA runs a window(s) is created; this will be created and sized according to operating system setup and display resolution. This can be changed by resizing the window, or selecting the maximize or minimize functions for example.

Menus, toolbar and status bars are created as per the current configuration settings. Other windows will also be displayed as per the current configuration.

Once the windows have been created and the mouse cursor is not the hour glass; the system is ready for use. To check on the current state of the system at any time use the Diagnostics – System Status option.


The first time the system starts after a new installation a welcome dialog is displayed. This gives some basic notes on using the system. This will be displayed every time the system starts until “Do not show this dialog again” is checked.

On this dialog the following statement is displayed:

“To view the event log chose Diagnostics | View Event Log from the menu or press the toolbar button marked i.”

This refers to the following: -

After a start-up problem If the Landscan WCA software failed to start or stop correctly then the system start-up is different. This failure to start may have been because the system configuration contained an error. The user then has a number of options to prevent this failure occurring again. The system will display the following dialogue:


From which the user can select a number of options to resolve the problem. These are as follows:

Use the current system configuration.

This option should be used if it is believed that the system error is not related to the current configuration.

Use the backup system configuration.

This will have been previously automatically saved by the system.

Use a previously saved system configuration.

This allows the user to load a configuration file saved using the Save Configuration option from the File Menu (use Alt F and V for key access).


Create a new (default) system configuration.

If this option is selected the user will have to restart the Landscan WCA software which will automatically create a default system configuration database. The user will then have to re-configure the complete system configuration (LPU/LSC addresses, Storage Management etc.).

Land recommends that consideration be given to the management of the Landscan WCA system configuration. To prevent protracted re-configuration of the system you should periodically backup the system configuration. The rate at which you backup depends on the frequency of configuration changes.

If a backup system configuration is available then use the following flowchart to help select the correct system configuration to use.


NOTE:

For information the current system configuration file is systemconfig.mdb. This resides in sub-directory \ConfigDatabase to the main installation directory. The main installation directory is \Landscan by default.

Toolbars The toolbars that are displayed when the Landscan WCA software is started can be enabled/disabled as required by the user. The toolbars are individually selectable, to enable or disable each toolbar go to the View menu and select the relevant toolbar option. If there is no check then the toolbar will not be displayed.

The toolbar is what is termed as a “dockable toolbar”; in such that it can be positioned within the main windows as required. To reposition any toolbar click and hold on the required toolbar (not a button of the toolbar), and move the toolbar to the position required. Release the mouse button and the toolbar resides in that position.

Error and Events If the status bar is displayed, it provides a visual indication of the current health of the system. It is then possible to use the icon at the far left of the toolbar (as shown below), or select the Diagnostics menu - View Event Log option, to open the Event Log Viewer which displays information about current errors and events within the system.


The color coding associated with the indicator goes from green, indicating normal operation, through amber to red, which indicates a severe fault within the system. For example, a Landscan Head that has been powered off.


It is possible to scroll through the events with the More button. To clear the current status indicator press Clear which will reset the color bar back to full solid green. Each event in the list has an icon indicator next to it. These are referring to the category of the alarm and will be one of the following:


The category of information denotes the severity of the message being displayed. An event is the most serious. Diagnostic and Debug messages are only used to provide information to help with the diagnosis of system problems. The formal definitions of the categories are as follows:

Category Type Description

Event An event shall be an action with the Landscan system, which directly affects the access to the required thermal data. The action, if unreported, would mean that the user would be unaware why the required thermal data was unavailable.

Warning A warning shall be an action within the Landscan system, which the user should be aware of because it could affect BUT does not directly affect the access to the required thermal data.

Information An information message shall be some data about the operation of the Landscan system that allows the user to understand the continued good operation of the Landscan system but has no impact on access to thermal data.

Diagnostic These are messages, added during development, to help the user to understand the operation and/or problems with the Landscan system.

Debug These are messages added during development for the sole purpose of allowing LAND engineers to diagnose faults.

The information available in the Event Viewer is invaluable for analyzing and solving problems, and will be required when discussing problems with Land Instruments technical support.

This is further discussed in the troubleshooting section.

NOTE:

You can click on any event for additional help.

Typical Operations

Configuring the newly installed software to accept input from an LPU/LSC and display the data This section deals with the basic system configuration for a 'real time' input, from an LPU/LSC.


NOTE:

When entering new values into the system, the range is not automatically displayed on the dialogue. And an error message will only be displayed when pressing the OK button of the associated dialogue box, as below.

The above example is for changing the display type.

Ensure all hardware installations are complete as described in previous sections.


Ensure that the Landscan Head is connected to LPU/LSC and this in turn is connected, via an appropriate network, to the Data Server. Ensure that it is possible to ping the LPU/LSC, which will test that the correct network IP address is configured.

From the main menu select the Configure - System menu option. From the basic configuration select the Line Scanner tab. Select the correct head type for the Line Scanner that is connected. Press OK to activate the configured settings. This completes the Basic configuration of the system.

Review the status bar; both the scanner and the LPU/LSC icons should be green. If they are red then there is a problem with retrieving data into the Landscan WCA system that should be addressed prior to continuing.

To create a display based on the data that is being received by the system it is necessary to select a display type. This is performed by selecting the display menu and the new display option.

The New View dialog is displayed,

LAND Instruments International Ltd. LANDSCAN WCA User Guide • 57

User Guide

Scope of User Guide

This user guide gives details of the Landscan WCA software. It provides:

General System Information

This includes details of system specifications, what file structure to expect when using the software amongst others.

Available Software Functions

This includes details of what the user can do by accessing the various menus that comprise the software user interface.

Communications Details

This includes information on the methods and protocols available for communicating with the Landscan WCA software.

58 • Scope of User Guide LAND Instruments International Ltd. LANDSCAN WCA

General System Information The following are some general points about the software, the philosophy upon which it is based and what the user can expect.

System Data Processing There are 3 areas in which the system processes the scan line data.

Control Processing

Is performed within the LPU/LSC processor provides up to 14 maximum, minimum and average zone calculations across the scan line. This data is available as analog outputs from the processor or as an Alarm relay. This data is typically used for process control and is normally passed to a PLC. This is a real time processing function processing each data line as it arrives.

Local Processing

This provides the same functionality as Control Zone Processing, but this zone information is only available at the Landscan WCA system, as an extra set of zones that can be used for process analysis. This is a real time processing function processing each data line as it arrives.

Product Statistics Processing

This is different from Control and Local Processing, in that it processes whole product data as seen at a particular Measurement station. A whole range of statistics can be generated, condensing the vast amount of scan line data into an easily understood group of statistical summary data for every product.

The Linearization Correction Function The Landscan Head output linear 4-20mA temperature signals. For example an LS10 (600 - 1200°C) unit outputs 4mA at 600°C, 12mA at 900°C and 20mA at 1200°C

However due to limitations of the linearization circuitry inside the Landscan head there is a slight distortion to this linear scale. This gives rise to a temperature measurement error called 'design conformity error'. This error is very small (negligible for many purposes) and varies with target temperature. The error curve is defined in the heads respective technical manuals.

LAND Instruments International Ltd. LANDSCAN WCA Scope of User Guide • 59

Design conformity error is the same for all heads of a given type. It is therefore straightforward to remove it in the Landscan Processor software. The LPU/LSC processor has a Linearization Correction Function which does just this. Residual linearization errors, after software error correction, are very small indeed (typically less than 1°C).

Available Software Functions The following gives an overview of each of the software functions. As the system is driven from the Windows graphical user interface the functions are initially described in terms of the menu options, toolbar options that the user can select. Other topics are detailed later.

The following menus are available to the user. The user uses the mouse to select these menus or the sequence of key presses defined.

60 • File Menu LAND Instruments International Ltd. LANDSCAN WCA

File Menu

File Menu Descriptions This menu is selected by using the mouse or by selecting Alt F from the keyboard (keystrokes to enter these options are given next to the titles). This menu displays items depending on whether the system is running or whether the manual start of the system has been selected.

Displaysheets A displaysheet can save the layout and feel of the windows currently displayed so that they may be used time and again even if they are changed by other users, without the need to reconfigure the display options. The user can do this by saving a displaysheet, which is stored in a file on the hard disk of the host computer. These are envisaged to be of particular use for repeated changes in personnel, shifts or products.

File – Save Displaysheet (Alt-F then S) This option allows the user to save the current display setup to a displaysheet file. The user should enter a name for the displaysheet file (in the File name box), the directory in which to store the displaysheet file, and press the save button.

File – Clear Displaysheet (Alt-F then D) This option allows the user to remove all display windows currently shown within the main display window.

LAND Instruments International Ltd. LANDSCAN WCA File Menu • 61

File – Open Displaysheet (Alt-F then O) This option allows the user to restore a previously stored displaysheet. The user has the option to look for a particular displaysheet file on the hard disk. This displays a file selection dialog box from which the user can select the file corresponding to their particular displaysheet.

Click on the file name in the list provided so that its name appears in the File Name box and presses the Open button.

It is also possible to change the displaysheet using a communications message (LDS).

Configurations A Configuration File can save the current configuration of the complete Landscan WCA system. The Save Configuration and Change Configuration options should be used with caution, as they will affect the setup of the system.

The Landscan WCA system automatically creates a backup copy of the current configuration database at a pre-defined interval.

File – Save Configuration (Alt-F then V) This option allows the user to save the current system configuration. This will copy the current configuration database (systemconfig.mdb) to the backup filename entered by the user.

File – Change Configuration (Alt-F then C) This option allows the user to change the configuration of the Landscan WCA software. If the user selects to do this then the software will automatically shutdown. When the Landscan WCA software is restarted the user is presented with a list of options to create a new configuration or load a previously saved configuration.


.

Use the current database

This option restarts the system with no change to the configuration

Use the backup database

This to option restarts the system with the most recently saved backup database.

Use a previously saved database

This option restarts the system with a database saved using the Save Configuration option. The user is prompted to select the location and filename to be loaded.

Create a new (default) database

This option restarts the system with a blank database. This allows a complete reconfiguration of the system.


LPU/LSC Configuration An LPU/LSC Configuration File includes all the parameters stored locally in the LPU/LSC, which have been configured by the Landscan Processor Configuration software. Key areas are:

• Scanner settings: type, speed, emissivity, height, tilt angle etc.

• Control zone model settings.

File – Save LPU/LSC Configuration (Alt-F then U) This option allows the user to save the configuration of a connected LPU/LSC processor to a database file on the Landscan WCA PC hard disk. The user selects the LPU/LSC to save the configuration from, the filename and location in which to store file. The LPU/LSC names are those defined in the Station Configuration.

File – Change LPU/LSC Configuration (Alt-F then L) This option allows the user to restore a saved LPU/LSC Configuration database. It should be noted that replacing the LPU/LSC configuration can change, amongst others the zone models configured within the LPU/LSC, the type of Landscan head connected to the LPU/LSC.

If the new LPU/LSC Configuration is not as expected then it can potentially compromise the process control ability of the Landscan system.

This option should be used with caution.

Print Options These options are used to configure and perform the print functions available within Landscan WCA.

File – Print (Alt-F then P) This displays the print dialog box from which the user selects the print out type required. Using this option print outs the current foreground display window, the foreground display window is the one with its title bar highlighted.

Printer name, type and status are displayed. The properties for that printer can be modified using the Properties button. Press OK to start the printer.


File – Print All (Alt-F then A) This displays the print dialog box from which the user selects the print out type required. This is different from the print option in that it prints all the display windows.

Printer name, type and status are displayed. The properties for that printer can be modified using the Properties button. Press OK to start the printer.

File – Print Preview (Alt-F then V) The user can look at the print out that will be generated prior to printing using this option.

To select to preview the contents of a window select that window by clicking on it, the title bar will typically highlight (this depends on system display properties). Then select print preview option from the file menu.


The user can then zoom in / out to review the print out prior to producing it. To produce the print out select the print button on this preview window or return to the file menu and use the print option.

Process

This dialog defines the key system settings, with regards measurement units, process and orientation naming and the number of connected LPU/LSC units.


Process name

This is the label, which will appear in the Landscan WCA title bar and on all printouts generated from Landscan WCA.

Units of Temperature

The temperature units used by the system can be either Celsius or Fahrenheit.

Units of Distance

This is used to configure the locale specific units for all system measurements; the options are Metric and US.

Units of product Width

These units are used by the displays, for information in the scanning dimension. The Line Scanner distance from product and Tilt angle settings (Line Scanner Tab) must be correctly configured for the non- degrees units to be accurate.

Units of Longitudinal measurement

These units are used by the displays, for information in the time dimension. If any non-time option is selected then the product speed must be correctly configured; otherwise the distance measurements will not be accurate.

Orientation Naming

These are the labels used by the system to define the Left of scan (this is the start of the scan) and the Right of the scan (the end of the scan).

Number of LPU/LSC

This is the number of LPU/LSC processors connected to the system, and will be limited by the License. For information on the license refer to the Help, About Landscan WCA dialog.

Equipment

This dialogue configures the network identities of the LPU/LSC processors, from which the system will gather the scanner data. It is essential that this dialogue is configured to exactly match the Network IP Address settings of the LPU/LSC processors, which is configured via the LPU/LSC front panel and the Landscan Processor Configuration software. Please refer to the LPU/LSC Processor user guide that is provided on the Installation CDROM.


LPU/LSC Processors

One Scanner and hence one LPU/LSC processor can be configured for each measurement station

Unit Label

This is a user-defined label for the station used by the system.

Network IP Address

The number entered here must exactly match the IP address of the LPU/LSC unit. The default address of the LPU/LSC is in the range 10.1.10.100-10.1.10.109, the least significant character of the address is selected using the front panel of the LPU/LSC.

If a change to the complete IP Address is required then it is necessary to make use of the Serial Communications using the Landscan Processor Configuration Software.

Maintenance - Take Unit Offline

It is necessary to take the unit offline whenever the IP Address of the station LPU/LSC is updated.

This option should also be selected whenever maintenance of the LPU/LSC is taking place, to prevent the Landscan WCA attempting to communicate with a LPU/LSC which is not present.

After the maintenance is complete deselect this option and press OK on the dialogue box. At this point the Landscan WCA software will automatically attempt to reconnect to the LPU/LSC processor at the designated IP Address.

Is Scantemp Process

This option should be selected when a ScanTemp model scanner is used at the station – it is not relevant when LS or LSP scanners are used.

Tracking

Introduction to Product Tracking


Products on the Process are constantly tracked by the system so that the identity of a particular product is known as it travels between the scanners. The identity of the product is either sent by the site computer system or is created by Landscan. The former is the most desirable since complications can arise since the scanners only have a point source view of the Process.

Care must be taken to understand your process distances, timings and events to correctly use these settings.

Generally a simple process may be able to use the system without sending PDI (Product Definition Information) data, but even then consideration must be made of the number of products on the process and between the scanners.

No PDI option

This assumes that a distance greater than each Measurement Station separates products on the Process. If this condition is not met, the system will not start up correctly, that is product numbers will not be assigned to the correct products. If this condition is not met then PDI should be used. Also it is assumed that products will not reverse at any point in the process.

PDI Available option (This option is recommended for most applications)

PDI can contain several items of data including the product name. Further information about PDI Messaging and the commands available can be found in Communications, PDI Command

The PDI data message must arrive at the Landscan system before the product is under the respective scanner; one or two seconds would be adequate (if this period is too long contact Land).

The data contained in the PDI message can be viewed on a Product Information display or in the communications diagnostic window.

Product Timing

Regardless of the mode used, products are timed so that product late and product stuck conditions can be detected. The result here will be twofold, an event will be logged to the Event Logger and the Tracking symbol on the Status bar will change color. The Tracking configuration dialog box performs the configuration.


This dialog offers basic error handling for problems with the application process, such as products stalling under the scanner. The naming of the products is controlled by the Product Configuration dialog.


The tracking algorithm will attempt to monitor the progress of products under the scanners, so in an application with several scanners and multiple products in the process at any time, it can deduce the name of a product arriving at each measurement station location. This algorithm is not ideal since it does not have any knowledge of the outside world, so we advise that for accuracy of product naming that communications is used and the product name is provided in a PDI message.

Reset Product Tracking Algorithm

If scanners have been taken out of service for maintenance or a product has stalled in the system, this will reset the tracking algorithm. The system will then begin to monitor for products at the first measurement station.

Store Untracked Products

If PDI messages are to be used for naming products but none are received OR there are faults with scanners in the system; then the tracking algorithm may not be able to adequately keep track of the products. In this case the products are said to be "UNTRACKED".

The icon on the status bar will be red and the name of the product will be Auto with a date / time stamp. By default any data associated with an untracked product IS NOT stored. You should select this option if you wish to store the data regardless of the tracking status.

In-between Station Line Tracking

There are two approaches to tracking scan lines within products between scanners, in a multi-scanner system. This function could be used to allow comparison of one product at each scanning station of a process or to provide a combined profile display for multiple Landscan heads situated side-by-side. This function should be used in conjunction with a delayed profile or combined data source display, see Display Configuration for detailed information on the display.

Time

Suggested Use - Lehr Cooling

This function should only be used in a process with a fixed thickness/length. At a minimum the distance between station parameter must be configured and an accurate process speed must be provided. It is recommended that when this tracking method is used an analog speed input is provided.

From this information, using the relationship between the distance and speed; Landscan WCA is able to calculate the relationship between the scan lines from each station of the product, producing an indication of the relative cooling between the stations.


Product Name

This function should only be used when the product determination information is provided from an external source, such as PDI Messaging.

The product at the scanning station is linked to all products with the same name from previous stations. In this situation it is possible to deal with products which have experienced a change in thickness/length from the previous station. To do this it is necessary to configure a length factor, see below for further information.

From this length factor Landscan WCA calculates the relative position of each scan line from the previous station to the current station scan line, allowing an indication of the temperature change during the process between the scanners.

DIAGRAM OF RELATIVE SCAN LINE POSITION

?? INVESTIGATE ??

It should be noted that the product tracking algorithms used for between station scan line tracking only provides an approximate indication of the relationship between the scan lines at each station.

This function should be used in conjunction with a delayed profile or combined data source display, see Display Configuration for detailed information on the display.

For each measurement station:

You should use the Product Configuration dialog box to enable the naming of products from the PDI messages.

Ignore Storage if no PDI

If this option is selected then products will not be stored if PDI is unavailable when the product is detected. In this case the Landscan WCA software will generate a product name which will be used on any displays showing this product. Once displayed the product data is lost.

Distance to Station

The distance between the mill stations, that is used in the tracking algorithm.


Max time at station

This is the absolute maximum time a product can remain under the scanner, if a time out occurs the product will be truncated. This provides a check for the product becoming stuck under the scanner in a process fault.

Max wait for product

This is the absolute maximum time a product can travel between measurement stations, if a time out occurs the product is deleted. This provides a check for the product falling off the process between measurement stations.

Length Factor to Station

Manual

The user is required to configure a parameter defining the relationship between the current product length and the length of the product at the previous station.

A Length Factor of 2 indicates that the product has doubled in length, or by definition that the product thickness has halved.

Auto

If this option is selected Landscan WCA calculates the length factor based on the relative change in product speed between the stations. For this to be successful an accurate product speed must be provided to the processor at each station.

The user is required to configure a parameter defining the relationship between the current product length and the length of the product at the previous station.

A Length Factor of 2 indicates that the product has doubled in length

Landscan WCA automatically calculates the length factor based on the relative change in product speed between the stations


Station

This dialog provides configuration of the Measurement Station position and name.

Station


This selects the LPU/LSC processor Measurement station location.

Name

The Name of the Measurement Station, this is used throughout the system, for example when selecting a display view.


Product

Station

This selects the Measurement station location for the product to be configured.


Product Name

The product name is used to identify products on the display and also used as the filename for the stored products on the hard disk drive. The product name can be defined by a number of methods, outlined below:

User Defined

In this situation the user can input a product name and number. The number is incremented as each new product arrives, thus providing unique product names for every product in the system.

PDI Control via Communications

The product name is defined from an external source using a PDI Message, see Communications, PDI Command for the relevant message structure.

If not available from

In the event that PDI messages are temporarily unavailable it is possible to configure any of the other options to be used as the product name.

Date and Time

The system date and time is used as the product name.

From Previous Station (all stations except station 1)

The product name is assigned from the previous station in the system.

For example PDI Messaging is used to configure the product name at station 1 and then at each subsequent station the same name is used without the need for additional PDI Messages.

In all cases, the station is identified by the addition of the station number to the product name.


Emissivity (Remote Control Option)

LPU_2E

This menu option is only relevant if the Remote Control Analog Output for Emissivity has been connected to the Landscan head. The LPU_2E drives the Emissivity input at the head to a value representing this menu option. Values can be specified in steps of 0.01.

LSC

LS-Scanner

This menu option is only relevant if the Remote Emissivity Control has been connected to the Landscan head. The LSC drives the Emissivity input at the head to a value representing this menu option. Values can be specified in steps of 0.01.

LSP-Scanner

The LSC drives the Emissivity input at the head to a value representing this menu option. Values can be specified in steps of 0.01.

Any change to the remote Emissivity setting will be immediately recognized by the LPU/LSC. The data from the sensor will be updated over a period of approximately one-minute. During this period the data given by the LPU/LSC may be incorrect.

Product determination

This group of options defines how the system determines what constitutes a product from the real time data stream from the LPU/LSC.

Hot Edges

Hot Edge Detection attempts to locate the positions of the first and last hot edges in the scan line. There are two forms of Hot Edge Detection, Automatic and Threshold.

Automatic (Percentage of Peak)

The LPU/LSC automatically finds the first and last hot edges within each scan line. This technique should successfully track most products. For every scan line the LPU/LSC detects the product temperature and the noise floor temperature and calculates the 'Edge temperature' threshold as a percentage of the difference between the Product temperature and the noise floor temperature. (see diagram below)


(The noise floor temperature is defined as the background temperature at the ends of the scan line.)

When this option is selected the Automatic (% of peak) parameter can be changed. This value would typically be set around 40 - 50%.

Threshold Temperature

This would only be used for applications with which the Automatic Edge Detection is inappropriate. For example if there is excessive background radiation to the sides of the product. This requires the setting of a fixed temperature level; the positions of the first and last points to exceed the temperature level are accepted as being the hot edges of the material. (see diagram below)

When this option is selected the Threshold Temperature parameter can be changed. The level will need changing to suit individual applications and products.


Timed

This function will splice the continuous product into discrete segments as defined by the time parameters entered by the user. This will allow the products to be more easily managed with regards to display, databasing and archiving.

Product Length

This defines the 'length' of product in hours and minutes.

Gap Between Products

This defines the time gap between each product.

Care should be taken when specifying this option that the defined time does not cause extremely large data files to be created.

Digital Input at LPU/LSC


This function leaves the control of the product detection to an external TTL or contact signal, for example from a PLC. Signal ON indicates product present and OFF indicates no product.

The LPU/LSC Digital Input must be defined by the user

Communications Control

This function leaves the control of the product detection to a plant computer, via a PDI message. A message is sent to switch the product on and a message is sent to indicate the end of the product, see Communications, PDI Command for the relevant message structure.

LPU/LSC Controlled (Landscan Batch Processor Only)

The Landscan Batch Processor can provide product detection information. If this option is selected it is necessary to configure the Landscan Batch Processor Product Detection.

Communication Override

If this option is selected, a PDI Communications message can be used to override Hot Edge Product Detection.

This option does not apply to other modes product detection.

Product May Reverse

This selection instructs the system to track products moving in both directions, typical applications include Hot Strip Mill Reversing stands.

Reverse Data (Coil Box)

Typically for use in a Hot Strip Mill application which employs a Hot Coil Box, this software function corrects the output from a Hot Coil Box such that the product data is shown consistently within the system.

Product Speed

This group defines how the distance data is calibrated, distance data is used in product determination and tracking. The more accurate the product speed information provided to the system the higher the quality of the subsequent data.


Fixed speed

When this option is selected the product speed in in/sec or mm/sec (dependant on locale), is manually defined by the user.

Analog speed input at LPU/LSC

The variable analog speed signal is applied to a user selectable analog input channel of the LPU/LSC. The current can be scaled to indicate a forward or reverse (negative) speed in in/sec or mm/sec. See Processor Inputs for further information.

Zero Boundary

This parameter is used to define a border around 0mm/sec which will be defined as 0mm/sec. This is necessary in an application that has forward and reverse speed to ensure that product stopped is recognised.

For example,

Zero Boundary = 200mm/sec

-200mm/sec to +200mm/sec will be 0mm/sec

From Distance between Lines (Rotary Applications using Landscan Batch Processor with Encoder Card Fitted Only)

When this option is selected the Landscan WCA software uses the equivalent linear speed generated by the Landscan Batch Processor from the rotary speed.

From Line Encoder (Landscan Batch Processor type with Encoder input Card –P option Only)

The linear product speed is determined by an encoder input signal.

The resolution should be configured and is used to convert the encoder input signal to a process speed.

The resolution value is derived from the encoder counts per revolution (cpr) and the circumference of the measurement wheel used.

For example using an encoder with 2500 cpr and a measurement wheel with a 500mm circumference gives a resolution value as follows:


mmcountsmm

cprresolution /20500

4250=

×=

Note: The encoder cpr value is multiplied by four due to the encoder card providing increased resolution.

Speed same as First Station (all stations except station 1)

This option can be selected assuming the product remains at a constant speed throughout the process. In order to calculate consistent distance information the current station will use the speed configured at the first station.

Product Cropping

This feature can remove a section from the start and end of the product prior to display and databasing. Typical applications are Hot Strip Mills where the leading and trailing edges of the product are removed prior to coiling.

Cropping Enabled activates the feature, and the amounts to be removed (the units are locale dependant) are defined in the Crop First and Crop Last fields.

Processor Product Detect This section refers to the Landscan Batch Processor Only and is used to configure the Product Detection Algorithm used within the Landscan Batch Processor. This will not affect the Product Determination configured within Landscan WCA.


Process Type

The type of process selected will affect which other options must be configured.


Linear

This option should be selected when the Landscan Batch Processor is used in a linear process.

Rotary

This option should be selected only when the Landscan Batch Processor is used in a rotary process.

Width Detection

The width detection is performed using Hot Edge Detection, which attempts to locate the positions of the first and last hot edges in the scan line. There are two trigger modes for Hot Edge Detection, Automatic and Threshold.

Automatic (Percentage of Peak)

The LPU/LSC automatically finds the first and last hot edges within each scan line. This technique should successfully track most products. For every scan line the LPU/LSC detects the product temperature and the noise floor temperature and calculates the 'Edge temperature' threshold as a percentage of the difference between the Product temperature and the noise floor temperature. (see diagram below)

(The noise floor temperature is defined as the background temperature at the ends of the scan line.)

When this option is selected the Automatic (% of peak) parameter can be changed. This value would typically be set around 40 - 50% - adjustments of this level may be necessary for more accurate widths.


Threshold Temperature

This would only be used for applications with which the Automatic Edge Detection is inappropriate. For example if there is excessive background radiation to the sides of the product. This requires the setting of a fixed temperature level; the positions of the first and last points to exceed the temperature level are accepted as being the hot edges of the material. (see diagram below)

When this option is selected the Threshold parameter can be changed. The level will need changing to suit individual applications and products.


First Edge Start Angle

This value is used to define the scan angle at which the processor will begin to look for the first hot edge in the scan line. This can be useful to remove reflections or hot objects from the extremities of the profile when detecting the first product edge.

Last Edge Start Angle

This value is used to define the scan angle at which the processor will begin to look for the last hot edge in the scan line. This can be useful to remove reflections or hot objects from the extremities of the profile when detecting the last product edge.

Length Detection

These parameters are used to define product length detection method.


When the linear process type is selected there are three options for the length detection trigger mode, however when the rotary process type is selected the only mode available is Digital Start + Length

Hot Edge Detection

The product length is triggered when the hot edge width detection is active.

Digital Start + Length

The product length is defined by a digital input start signal followed by a configured product length. The product length must be defined in the Product Duration.

Digital Start + Stop

The product length is defined by a start and stop digital input signal.

Product Length

This value defines the product length following a digital input start signal and is used if the product length trigger mode Digital Start + Length is selected. For linear process types the length is defined in mm or inches (depending on the locale settings), when a rotary process type is selected the product length is defined in degrees.

Product Start Trim

The product start can be trimmed by defining the number of mm to remove. This can be useful if a product trigger is prior to the start of the actual product. This parameter is only available for linear process types.

Product End Trim

The product end can be trimmed by defining a number of mm to remove. This can be useful if hot objects following the product cause the system to remain triggered on a product. This parameter is only available for linear process types.

Maximum Lines

The system uses a buffer to hold the product data. This value defines the buffer size and should be greater than the expected maximum product length.


Rotary Triggers

This option can only be configured for a rotary process type, eg. Rotary Thermoforming machines, all information except the number of stations can be automatically defined using the Diagnostics, Rotary Triggers menu.

Number of stations

This parameter sets the number of stations or stages of the machine. The number of stations can range from 1 to 4.

Trigger Station

This defines the station that immediate follows the digital trigger input signal.

First Station Offset Angle

This parameter defines the offset angle of the first station relative to the trigger signal.

Second Station Offset Angle

This parameter defines the offset angle of the second station relative to the trigger signal.

Third Station Offset Angle

This parameter defines the angle offset of the third station relative to the trigger signal.

Fourth Station Offset Angle

This parameter defines the angle offset of the fourth station relative to the trigger signal.

Heater Field Tracking

These parameters are used to define the tracking applied to the heater fields defined within the Landscan Batch Processor.

Product

The defined heaters fields track the detected product.

Fixed Fields


The defined heater fields are fixed relative to the aperture of the scanner head.

Width/Length Offset

These parameters allow the entire field grid to be repositioned relative to the center of scan.

Processor Speed Control

This option can only be configured for a linear process type.

Fixed speed

When this option is selected the product speed in in/sec or mm/sec (dependant on locale), is manually defined by the user.

Analog speed input at LPU/LSC

The variable analog speed signal is applied to a user selectable analog input channel of the LPU/LSC. The current can be scaled to indicate a forward or reverse (negative) speed in in/sec or mm/sec. See Processor Inputs for further information.

From Line Encoder (Landscan Batch Processor with optional –P Encoder Card Fitted Only)

The linear product speed is determined by an encoder input signal.

The resolution (counts/mm) should be configured and is used to convert the encoder input signal to a process speed.

The resolution value is derived from the encoder counts per revolution (cpr) and the circumference of the measurement wheel used.

For example using an encoder with 2500 cpr and a measurement wheel with a 500mm circumference gives a resolution value as follows:

mmcountsmm

cprresolution /20500

4250=

×=

Note: The encoder cpr value is multiplied by 4 due to the encoder card providing increased resolution.


Processor Inputs The processor input configuration is dependant on the type of processor connected to each station.

LPU_2E Processor

The hardware configuration of the LPU_2E can include up to 8 analog voltage input channels. These inputs can be used to provide product speed information, spot thermometer inputs etc. All this data is displayed and stored by the system in the database.

LSC Processor

Up to 3 Digital/Analog Input and Output Cards (DAIO) may be fitted. Each card provides the following inputs, see Output Page for the specification of Analog and Digital output channels:

Input Type No. of Channels Specification Digital 4 Closed contact with respect to isolated 24V,

active high

Analog 4 Differential, milliamp or voltage - link selectable. 0 to 1/2/5/10V range, scaling span and offset - independently software selectable

The status of each channel is updated once per scan line.

When a third DAIO card is fitted, the Analog and Digital inputs of the card are disabled. This is because only 8 inputs are available at any time.

Analog Input Link Positions

The analog inputs can accept either voltage (V) or current (mA) signals. Each of the four channels may be independently set using jumper links on the DAIO Card.

For voltage input:

Set the appropriate link to "V" (see diagram below or the Processor User Guide for further information)


For current input:

Set the appropriate link to "I" (see diagram below or the Processor User Guide for further information)

The dialogue box is then used to configure each analog or digital input.


Station Number

This selects the LPU/LSC Processor Measurement station location.


Analog Inputs

Label

This is a text label that can be applied to the analog input channel; it is used by the system displays etc.

Channel On

Each of the analog input channels can be individually enabled within Landscan WCA. In order for the analog input to read and process signal data, the channel must be turned on.

Function

Process Input

This is the default option and should be used for any Analog input signal other than speed. This could be used for example to provide a measure of product thickness to the LPU/LSC processor.

Process Speed

This option should be selected if the input is to be used as an Analog speed input to the LPU/LSC processor.

Voltage Range

LPU_2E

The analog input range of the LPU_2E offers a 0 to 10V span or a 0 to 1V span. The LPU_2E will intelligently decide which span setting to use based on the limits of the working span given by the user.

The bottom and top limits of this range should fall between 0 to 10V.

LSC

Voltage

The analog input voltage range of the LSC offers a 0 to 1V, 0 to 5V or a 0 to 10V span. The LSC will intelligently decide which span setting to use based on the limits of the working span given by the user.

The bottom limit of this range is fixed to 0V and the top limit of the range should fall between 1 and 10V.


Current

The analog input current range of the LSC is 0-20mA. When the jumpers of the DAIO card are set to current, the voltage range of the input channel must be set, by the user as 0 to 5V.

User Scale

The user can specify the linear scaling of the analog input signal to match the input range previously configured. The bottom scale translates to the bottom of the input voltage range and the top scale translates to the top of the input voltage range. These scaling values can be positive or negative.

LSC Processor with 4-20mA Current Input

It should be noted that when using 4-20mA Current Input, that this relates to 1-5V of the voltage range. However as stated previously the bottom limit of the range is fixed at 1V. So the range should be configured as though the current input is 0-20mA

For example, analog input configured as remote speed, where 4-20mA equates to 0-20000mm/sec. So the user scale should be configured:

Bottom Limit = -5000

Upper Limit = 20000

Offset

This is a user signal adjustment to calibrate any deviation in the analog input readings at installation, for example signal attenuation. Readings derived after offset adjustment will remain within the scaling range previously configured.

Digital Inputs

Label

This is a text label that can be applied to the digital input channel; it is used by the system displays etc.

Channel On

Each of the digital input channels can be individually enabled within Landscan WCA. In order for the digital input to read and process signal data, the channel must be turned on.


Function

Process Input

This is the default option and should be used for any Digital input signal other than Product Start and End.

Product Start

This option should be configured for the digital input to be used a Product Start signal for Product Determination or Process Product Detection (Landscan Batch Processor only)

Product End

This option should be configured for the digital input to be used a Product Stop signal for Product Determination or Process Product Detection (Landscan Batch model Processor only)


Line Scanner


Station

This selects the Line scanner Measurement station location.

The following parameters apply to each connected LPU/LSC processor.

Disable Scanner for Maintenance

With this option selected the system will ignore any events generated by this scanner. For example, if it is disconnected for maintenance.

When this option is selected the relevant scanner indicator in the status bar will change to yellow.

Scanner Settings

This group configures all the parameters of the Line Scanner Head connected to the LPU/LSC processor.

Head Type

Defines the scanner Model Connected to the LPU/LSC, select from the list available.

Scanner Speed (Remote Control)

Only relevant for LS Scanners

LPU_2E

This menu option is only relevant if the Remote Control Analog Output for scan speed has been connected to the Landscan sensor head. The LPU_2E can drive the scanning motor in the head to run at the speed selected in this menu option. Values can be specified in steps of 1Hz. (not available with LSP scanner types)

LSC

This menu option is only relevant if an Analog Output has been configured to act as a Remote Speed Control AND the Analog Output chosen for the scan speed has been connected to the Landscan sensor head. The LSC can drive


the scanning motor in the head to run at the speed selected in this menu option. Values can be specified in steps of 1Hz. (not available with LSP scanner types)

The LPU/LSC can automatically detect and track the speed of the scanning motor and will yield valid data when it has established that the motor has stabilized at a valid speed.

Any change to the remote scan speed setting will be immediately recognised by the LPU/LSC. After adjustment of the sensor head remote control signal, it may take several minutes for LPU/LSC to confirm that the scanning motor has stabilized, and valid Fast Temperature data is being received.

The diagram below shows the effect of varying the scan speed between 5-25Hz

Distance from Product

LPU/LSC

This is the distance between the scanner head window and the surface of the product measured perpendicular to the scanner head window. The units are either inches or millimeters, depending on the locale settings defined on the Process page.


Landscan Batch Processor

This is the distance between the scanner head window and the surface of the product measured perpendicular to the product. The units are either inches or millimeters, depending on the locale settings defined on the Process page.

Tilt Angle

This is the angle subtended by the scanner head to the horizontal axis of the product, in degrees. The processor uses this parameter to correct for distortions caused by the scanner head being tilted with respect to the product surface. The correction applied to the scan line data depends upon the processor type.

LPU/LSC (all types of scanner)


Landscan Batch Processor

Reverse Scan Direction

Selection of this setting (check displayed in box) will result in the processor returning the values of each scan line in reverse order. For example if 1 of 3 scanners were mounted in the opposite orientation due to mounting constraints, then the data from that scanner could be reversed to match the other 2 scanners.

Temperature Offset Adjustment

This provides the facility to add or subtract a fixed temperature offset to the calibrated temperature data that is displayed, by up to ±200° (C or F) .

When applied, an offset value of -10° will cause the displays, zones, analog outputs etc. read 10° below the calibrated temperature.

Enable Internal Ambient Temperature Sensor (where available)

In Landscan heads fitted with an Internal Ambient Temperature sensor (refer to Landscan head documentation) selection of this setting causes an alarm to be triggered if the internal ambient temperature (within the Landscan head) exceeds its maximum safe value. These values can be found in the documentation for the appropriate Landscan head. The range of this sensor is -10 to + 90C and it provides a linear 4-20mA output.


Input Signal Conditioning

Defines the data pre-processing function to be applied, select either OFF, Averaging or Peak Picking.

Averaging

Provides the average temperature over a user determined number of scan lines, particularly useful when scanning a product where there is electrical or thermal noise.

Each sample in the scan line is averaged with its corresponding sample positions over the last x scan lines. The resulting temperature is allocated to this sample.

The graphical illustration below shows the typical output obtained using the averaging function - the output signal is smoothed.


Peak Picking

Provides the peak temperature value, particularly useful when scanning a product with heavy scale, and as in the averaging function, this is on a per sample basis.

If the peak temperature of the sample is greater than the previous corresponding sample then its temperature is used as the peak. If it is less than the previous corresponding sample then a decay is applied which is proportional to the number of processed scan lines selected

Over n Scan Lines

The pre-processing function, if active, is applied over 2, 4, 8, 16 or 32 scan lines input.


Correction

This dialogue provides configuration of the Landscan Batch Processor rotary product correction settings. The following options are available.


The following parameters apply to each connected Landscan Batch Processors

Enable Correction Mode

Selection of this setting (check displayed in box) will result in the processor applying a rotary correction algorithm to product data. The rotary geometry correction mode is used to correct for distortions to the product data caused by rotating products as they appear to the Scanner Head. The correction algorithm uses geometrical data from the process to correct for this distortion.

The following parameters are required to perform the Rotary Geometry correction.

Scanner distance to center of rotation

This is a measurement of the distance from the center of rotation of the rotary machine to the center of the scanner temperature profile. This can be configured by placing a hot object in the profile of the scanner and measuring from the center of rotation to the 0 degree scan angle point.

Measured area width

This is a measurement of the width of the area to be corrected. The measured area width should always be greater than the expected product width.

Measured area length

This is a measurement of the length of the area to be corrected. The measured area length should always be greater than the expected product length.

Measured area length offset

This is a measurement of the offset from the center of the scan line to the center of the measured area length.

Measured area width offset

This is a measurement of the offset from the center of the scan line to the center of the measured area width.


Configure - Communications (Alt C then M) This allows configuration of external communications (with other plant computers). The Landscan WCA DataServer acts as the Server when communicating with other Plant Computers.

Communication Settings

TCP/IP Communications Serial Communications

The license controls the number of communications connections. The license controls the protocol and transport mechanism (RS232/TCP/IP) used on the particular connection.


For each connection the user can select whether TCP/IP or Serial Communications is used. Depending upon connection type only the appropriate configuration parameters are displayed.

For each licensed TCP/IP connection the user can configure:

IP Address

The IP address of the client connection can be modified if a connection is not currently connected.

IP Port Number

The port number for the TCP/IP port connection, a TCP/IP "port" can be thought of as a private communications line where the port number is used to uniquely identify each unique connection between two devices. The concept is very similar to any other type of port on the PC (serial, parallel, etc) except that instead of having a physical connection, the TCP/IP protocol creates a "virtual port" and the network software is responsible for routing the data in and out of each virtual port.

The external communications interface should not use the same IP port number as that used for LPU/LSC communications. The default IP port number for LPU/LSC communications is 1050, for other external communications it is 2011.

124 • Data Processing Menu LAND Instruments International Ltd. LANDSCAN WCA

Data Processing Menu

Data Processing – Control Processing (Alt-P and C) This group of dialog boxes are used to configure the processing performed within the LPU/LSC Processor and equivalent functions performed within the WCA software.. They are also used to assign processed information to both analog and digital outputs of the LPU/LSC Processor.

LAND Instruments International Ltd. LANDSCAN WCA Data Processing Menu • 125

Zone Processing

This dialog configures the Control Zone model data processing that resides in the LPU/LSC. The data from these functions is used to control the LPU/LSC zone analog outputs and the alarm outputs. The LSC may have 4, 8 or 12 optional outputs and 4 or 8 optional inputs. The LPU may have 2, 6, 10 or 14 outputs and 4 or 8 optional inputs.

The Control Zones are configured across the width of scan or the width of the detected product and are measured along the length of the product,


Station


Each of the stations has 14 unique control zone settings (even though the LSC processors are limited to 12 outputs).

Zone Time Function

Generally, the application of a Time Constant Function creates a processing zone area over the moving product. This zone area is dependent upon the scan speed and the value of the time constant. For example, if the scanner is set for operation at 10Hz and a time constant at one second is used, then the zone area will cover ten scanned lines of the product.

Apply

This turns on the time constant calculations for the zone peak picker, valley picker, and zone average.

The time functions are very useful for scanning a material with heavy scaling, or a narrow material such as wire. With the Time Function applied, zone processing functions are applied to an area of the product. This 'area' keeps pace with the incoming scan data, rolling forward as a block as each new scan line is processed.


Zones time function explained

The values of Minimum, Average and Peak are re-calculated continuously by taking the values calculated for each scan line and applying the zone time constant.

Minimum

Is the Valley picker; the value recovers to the scanner top temperature within the time constant period. Useful for ignoring 'hot spots' caused by surface changes with galvanised products.

The zone output will follow the minimum temperature within the zone area. Each scan line is processed in turn, if the next scan line has a minimum temperature lower than the previous scan line within the chosen zone then this new minimum value is used for the zone output. However if the next scan line has a minimum temperature higher than the previous scan line within the chosen zone then a time constant is applied to the zone output.

Peak

This is the Peak Picker, the value decays to the scanner bottom temperature within the time constant period. Useful for ignoring scale or gaps in wire.

The zone output for this option is similar to the Minimum zone option except that the action is reversed. The zone output will follow the maximum temperature within the zone area. A time constant is applied to the zone output if the temperature is falling.

Average

Is a running average calculated as the average of the average of the individual averages of each line for the number of lines within the time constant. This has a smoothing effect upon the zone data.

Hold Outputs Between Products

If On, the analog outputs will hold the output values from the last hot product detected using the zone model selected. If Off, the outputs will represent whatever is calculated by the corresponding zones. i.e. If there is no product within the field of view of the scanner, the outputs will read the background temperature. Note that if Hold Outputs between products is On the alarms will not hold their state until the next product is detected.

(Batch Processors with V1.1.0 firmware and above do hold alarms between products)


The dialog allows the user to segment either the product or the full scan width into a series of up to 14 zones that can overlap if required. For each zone it is possible to calculate the maximum, minimum or average temperature. Used in conjunction with the Hot Edge Detection function, in the product dialog zones can track a moving target.

The configuration of each zone is performed on an individual dialog, to edit the parameters of a zone, single click the mouse on a parameter of that zone.

Individual Control Zone Configuration


Zone Configuration

Label

This is a text label that can be applied to the zone; it is used by the system displays etc.

Tracking

This option configures each individual zone to either track with the hot product if enabled or align with the scanner field of view and thus the industrial process if disabled.

Off

The zones are defined relative to the full scan width.

Tracks Product

The zones are defined relative to the tracked hot product.

Track Product in Borders

The zones are defined relative to the tracked hot product. The product tracking algorithm is only functioning within the defined region of the full scan width.


Units

The zones can be defined in either percentages or the measurement units of the system.

Reference

Each zone can be defined relative to a reference position. The reference options are "Start, Center or End". Percentage zones are always referenced to the start of the hot product or the start of the scan width. If track product is enabled, the reference positions apply to the hot product and if the track product is disabled, the reference positions apply to the full scan angle.

Start and End

This defines the size and position of each zone. The values must be specified in the units selected for each respective channel.

How the zones are configured using Percentage units

When defining a zone using percentage units and product tracking is enabled, then 0% to 100% would represent the width of the hot product as identified using the hot edge detection algorithm. This method


would be used for a zone across the product width which may be varying or where the product moves about within the scanner field of view whilst being processed.

0% is the start reference point and 100% is the end reference point. Thus 50% represents the center of the hot product or the center of the scan width. Percentage defined zones can be specified to 0.1% allowing a resolution down to 1 sample.

How the zones are configured using Distance units

This defines the size and position of each zone as an absolute measurement in mm or inches. When defining a zone using specific units of measurement either millimeters or inches, then two forms of data can be obtained: product related or process related.


If the product tracking is disabled, then the zone reference allows a zone to be fixed with respect to the process, for example yielding data from an area cooled by a fixed position vent.

If the product tracking is enabled, then the zone reference allows a zone to be fixed with respect to the product, for example, yielding data from an area adjacent to each hot edge.

The range of a zone, which starts at a reference point, will have one value of 0 and the zone size will be determined by the second value. A zone in proximity to a start or end point reference point will have two values describing the zone start and zone end positions. A zone referenced to the center has one value describing the zone size symmetrically about the center of the product or process.

When measuring in mm/inches the range is detailed in mm/inches (depending of the locale settings) but will be dependent upon the tilt angle of the scanner and the distance from the scanner to the target as setup in the Line Scanner menu. See the example below where the scan angle corresponds to an absolute width of 1500mm, hot edges have been detected at -20° and 16°, the center of the product is at 2° and units have been set to mm.


Processing

For each line scanned the processing for each zone can be independently set:

Off

No output. If you have cooling rate calculations enabled and the zones are off then no cooling rate calculations are performed.

Minimum

Finds the minimum temperature of all the samples within the zone.

Average

Calculates the average of the samples within the zone.

Peak

Finds the maximum temperature value of all the samples within the zone.

Quantile

This function performs a peak sample rejection algorithm to remove unwanted samples from the zone value. Firstly the samples from the zone are sorted into order of temperature values. These samples are then converted to a percentage value 0% to 100% where 0% represents the sample value at 0% of the samples and 100% represents the value at 100% of the samples.

Any samples above the required percentage of the total number of zone samples are rejected. The required percentage of the total number of zone samples is entered using the Quantile/Avg Threshold Value input field.


Average Threshold

The Average Threshold function performs a similar function to the standard average function with the addition of the ability to define a threshold level for the calculation. The minimum and maximum temperature value in the zone


is used to create a percentage index representing the threshold temperature. Only values that are above the threshold value are included in the average calculations.

The zone output depends on the processed function of the scanned line shown according to width of the zone set.

For zones that overlap the edges of the hot product, the zone statistics are derived from the hot product portion of the data only.

A zone, which is OFF, cannot calculate data for the alarm and output channel associated with it, thus the alarm will be turned off and the Analog outputs will be set to 0mA.


Zone Alarms


LPU Processor

This dialog allows the user to configure a maximum of 14 alarm relay outputs each of which will be activated at a threshold temperature value by the corresponding zone processed temperature. If the associated zone 'type' is set to Off then there is no zone data on which to activate the alarm, and the alarm relay output will be set to OFF.

LSC Processor

This dialog allows the user to configure a maximum of 14 alarms each of which will be activated at a threshold temperature value by the corresponding zone processed temperature. If the associated zone 'type' is set to Off then there is no zone data on which to activate the alarm, and the alarm output will be set to OFF. If an external warning of an alarm condition is required, each alarm can be mapped to a digital output.

Configure Groups

The Group Configuration window allows user to group individual fields associated with a previously created field configuration. For information relating to the creation of a field configuration refer to section Heater Field Configuration.

Following the grouping of fields statistical calculations are made that relate to the data in all the fields of the group. For example if a field group consisted of four fields then the mean temperature value for the group would be derived from the mean temperature of every sample in the four fields.

The following settings can be configured for each field group:

Group

This defines the unique grid index of the field group.


Label

This defines a user specific description for the field group.

Lo Alarm

This defines the low alarm trigger temperature for the field group. If the field group mean temperature falls below this level then the field group low alarm will be activated.

Hi Alarm

This defines high alarm trigger temperature for the field group. If the field group mean temperature is above this level then the field group high alarm will be activated.

Avg Threshold

This defines minimum temperature threshold level for mean temperature field group calculations. If the temperature of any sample in the field group is below this threshold temperature then it will not be included in the field group calculations.

The following options are available on the window:

Add Group


Following selection of the add field group function from the Heater Group Configuration window a new field group may be added to the field group grid at the next available position in the field group list.

All the individual group parameters can be configured; refer to previous section for a description of the field group parameters.

To configure the field group a list of available heaters is shown. Following the selection of the heaters from the available heater field list the Add button should be selected. The Add button moves the selected heaters from the available heater list to the Selected Heater List. The selected heater list shows the heaters that will form the group following the user selecting the OK button.

The Next button can be used to add further field groups to the field group grid.

Edit Group


Following selection of the edit heater group function from the Heater Group Configuration window an existing field group may be configured.

All the individual group parameters can be configured; refer to previous section for a description of the field group parameters.

To edit the field that forms the group the user can add new field from the available heaters list and selecting the Add button. Heaters can be removed from the group by selecting heaters from the Selected Heater list and selecting the Remove button.

The selected heater list shows the heaters that will form the group following the user selecting the OK button.

The Next and Previous buttons can be used to edit further field groups of the field group grid.

Delete Group

Selecting this option deletes the currently selected field group.

Delete All

Selecting this option deletes all the groups in the field group configuration.

Load File

The load file option can be used to import previously saved field group configuration files. Refer to section 'Save As' for information regarding saving field group configurations.

Save As

The save file option allows the user to export the current heater group configuration to a data file. This file can be imported into the software using the load file option refer to section 'Load File


Show/Hide Map

The field group map window shows a graphical representation of the current field group configuration. Each field group is represented by an area of similarly colored fields.

The map window can be used in conjunction with the various field group configuration options to provide a simple method of creating and editing field groups. Refer to sections 'Add Group' and 'Edit Group' for further information.


Data Processing – Local Processing (Alt-P and L)

Local Zone Processing

This dialog configures the Local Zone data processing, which is a separate zone model, independent of that which exists in the LPU/LSC. These zones do not provide any control and only reside within the Landscan WCA Software.

The Local Zones are configured across the width of scan or the width of the detected product and are measured along the length of the product,


Station


Each of the stations has 14 unique control zones.

The dialog allows the user to segment either the product or the full scan width into a series of up to 14 zones that can overlap if required. For each zone it is possible to calculate the maximum, minimum or average temperature. Used in conjunction with the Hot Edge Detection function, configured in the product dialog, zones can track a moving target.



Individual Local Zone Configuration

Zone Configuration

Label

This is a text label that can be applied to the zone; it is used by the system displays etc.

Cross Tracking

This option configures each individual zone to either track with the hot product if enabled or align with the scanner field of view and thus the industrial process if disabled.


Off

The zones are defined relative to the full scan width.

Tracks Product

The zones are defined relative to the tracked hot product.

Units


Reference



Start and End



When defining a zone using percentage units and product tracking is enabled, then 0% to 100% would represent the width of the hot product as identified using the hot edge detection algorithm. This method would be used for a zone across the product width which may be varying or where the product moves about within the scanner field of view whilst being processed.








When measuring in mm/inches the range is detailed in mm/inches (depending of the locale settings) but will be dependent upon the tilt angle of the scanner and the distance from the scanner to the target as setup in the Line Scanner menu. See the example below where the scan angle corresponds to an absolute width of 1500mm, hot edges have been detected at -20° and 16°, the center of the product is at 2° and units have been set to mm.


Processing

The processing is performed for each line scanned; the processing for each zone can be independently set:

Off

No output. If you have cooling rate calculations enabled and the zones are off then no cooling rate calculations are performed.

Minimum

Finds the minimum temperature of all the samples within the zone.

Average

Calculates the average of the samples within the zone.


Peak

Finds the maximum temperature value of all the samples within the zone.

Quantile

This function performs a peak sample rejection algorithm to remove unwanted samples from the zone value. Firstly the samples from the zone are sorted into order of temperature values. These samples are then converted to a percentage value 0% to 100% where 0% represents the sample value at 0% of the samples and 100% represents the value at 100% of the samples.

Any samples above the required percentage of the total number of zone samples are rejected. The required percentage of the total number of zone samples is entered using the Quantile/Avg Threshold Value input field.


Average Threshold

The Average Threshold function performs a similar function to the standard average function with the addition of the ability to define a threshold level for the calculation. The minimum and maximum temperature value in the zone is used to create a percentage index representing the threshold temperature. Only values that are above the threshold value are included in the average calculations.


The zone output depends on the processed function of the scanned line shown according to width of the zone set.

For zones that overlap the edges of the hot product, the zone statistics are derived from the hot product portion of the data only.

Zone Results Processing

This function is used to generate statistical information from a defined length of the Local Zone.

Offset from Start

This defines the position of the processed area relative to the length of the product.

Start

The start position in mm.

The start of the product is 0mm

End

The end position in mm.

Local Profile Processing

This dialog configures the Local Profile Processing, it allows the user to display up to 14 Temperature Profiles configured at pre-determined points along the length of the product. It could be considered as a Local Zone measured across the width of the product.

The Local Zones are configured along the length of the product and are measured across the width of the product.

The Local Profile Processing is used in conjunction with the Local Profile Display.

Station


Each of the stations has 14 unique Local Profiles.



Individual Local Profile Configuration


Profile Configuration Label

This is a text label that can be applied to the profile; it is used by the system displays etc.

Longitudinal Settings

These settings are used to configure the position of the Local Profile along the length of the product and the processing applied to the selected length area.

Process.

The processing is performed for each sample point along the length of the product, e.g. the sample 1 of each scan line along the length of the Local Profile is processed together. The processing for each Local Profile can be independently set:

Off

Local Profile disabled.

Minimum

Finds the minimum temperature of all the samples within the selected length area.

Average

Calculates the average of the samples within the selected length area.

Peak

Finds the maximum temperature value of all the samples within the selected length area.

Offsets from start

These settings configure the position of the Local Profile along the length of the product. These are always defined in mm/inch (depending on the configured locale settings), referenced from the start of the product.

Start and End

This defines the size and position of each Local Profile.


Example:

A Local Profile configured with

Start = 1000mm

End = 1005mm

Would generate a 5mm Local Profile across the product starting 1000mm into the product.

Transversal Settings

These settings are used to configure the width settings of the Local Profile. It is possible to determine if the Local Profile is measured across the complete scan width or relative to the detected product.

Tracking

This option configures each Local Profile to either track with the hot product if enabled or align with the scanner field of view and thus the industrial process if disabled.

Off

The Local Profile is defined relative to the full scan width.

Tracks Product

The Local Profile is defined relative to the tracked hot product.

Orientation


This is a global setting for all the displays, to orientate the data in a particular direction, so the Landscan displays follow the same orientation as other display systems.

Along the product

This controls the direction the product moves across the screen. In a control room situation this would be changed, so that the product moves across the screen in the same direction as the product moves past the control room window.

Across the product

This defines the default left and right positions of the displays.

Change Display Orientation on Reverse Product

When this option is selected the orientation of the display is changed to match the apparent direction of the product movement.


Defaults

This is a global setting for all the displays configured for the measurement station.

This selects the measurement station

X Axis

This defines the default size of the display longitudinal axis that appears in the change View dialogue. The size can be further manually adjusted, from within that dialogue.


Cooling

This function is only applicable to systems that have 2 or more scanners connected.

The cooling rate calculations are performed on configured zones. If the zones are not configured then cooling rate calculations are not made. To help configure the zone model required review Data Processing - Control Zones.


This dialogue is used to configure the cooling rate calculations for each zone between the scanners. The required scanners are entered in the Station and From Station fields. Having selected the required scanners the cooling rate calculations are configured on a PER ZONE BASIS.

For any zone calculation it is possible to specify :

Under Cooled

The value in the selected units, which specifies the minimum acceptable cooling rate. When displaying the calculations if this limit is reached then the display indicator goes red.

Target Cooling

The value in the selected units, which specifies the target-cooling rate. When displaying the calculations if result is within the Under and Over limit then the display indicator is green.

Over Cooled

The value in the selected units, which specifies the maximum acceptable cooling, rate. When displaying the calculations if this limit is breached then the display indicator is red.

The cooling rate calculations can either be in Degrees / Second or Degrees / Minute. The values you enter for each zone are modified automatically to the correct rate units.

Reverses the scan line direction on the monitor.

Overwrite mode

This is only available with the profile display, and leaves all the old profile traces on the screen. This can give you a good measure of temperature profile variance over time.

Show Full Width

If this option is enabled the full scanner scan angle will fit the display, if this option is disabled the “Show Product from” x to y is displayed. This defines the limits of scan angle displayed. By setting values within these limits, it is possible to zoom in on any particular section of the scan.

If the units of measurement are mm or inches then the values will refer to the distance relative to the center line which is zero.

Center Product

If this option is enabled the center of the product which is defined as the mid point of the hot edges will be aligned to the '0' degrees position on the displays. This is useful if the product is moving about in the scanners field of view, since it can remove lateral movement on the display. See Product Determination.

See Display Types for a list of available display types and descriptions


Font Size

The sizes of fonts are available, for the text of the view.

Show Grid lines

Available for some displays, this will plot grid lines over the display.

Update Display every n lines

This will reduce the number of display updates, for machines with less processing power. On applications that only have small products, for example automotive windscreens, the clarity of data displayed is greatly affected by this setting.

Auto configure

None

This scales the display to the values entered on this dialog box.

From PDI Information

If set the system will look at any incoming communications PDI messages, and will re-scale the temperature and distance scales to fit the data in the PDI message, if it is available. This allows the system displays to be automatically updated to suit the temperature of the product currently being produced.

From Data

This function can only be used on displays showing the whole product (Auto Size Display option set on Change Data Source dialog).

This scales the temperature range of the display to the maximum and minimum temperature values of the actual data.

Scales

This option allows the user to configure the position of the scales, these can be displayed on the:

Left

Right

Or Both sides


Maximum Temperature and Minimum Temperature

Maximum Temperature defines the temperature at the top of the vertical axis. Minimum Temperature defines the temperature at the bottom.

The max and min temperature values can be chosen to suit the temperature range of the particular scanner, or they can be set to define a narrow range to reveal details of interest in a particular temperature band.

Print at end of product

This produces a print out of the current product when it is completed. This is only available when the display shows the whole product (Select the Auto Size Display option on the Change Data Source dialog box).

Data Source Properties This dialog provides access to all the various forms of data within the system.

Live scan line data passes into the system from the LPU/LSC processors at each measurement station, this continuous data stream is then segmented into products by the Product Detection function. This data is then stored in a short term RAM cache, where it is made available for the system. For medium term storage the data can be passed to a large database on disk and for permanent records the data can then be moved to an Archive, which may be a tape. All this stored data is then available to the user interface, data is found through the use of a Product Locator, which can use Query requests to help find the information.

Measurement Station

This narrows the focus of the data to a particular scanner position.


Data Source

This selects the source type of data as either:


Real Time Scanner

This data source is live data direct from the scanner; this is a camera view where the data may comprise of products and gaps. Everything including the gaps will be seen on the displays. With this selection any displays will continuously display the real time scanner data.

Real Time Multi Scanner

This data source is live data direct from multiple scanners; this is a camera view where the data may comprise of products and gaps. Everything including the gaps will be seen on the displays.

Real Time Product

This data source is product data, (i.e. No gaps) that is currently under the scanner. With this selection the displays will display every new product as it arrives, ignoring all the gap data.

Database

This data source allows individual products to be accessed from the database.

Archive

This data source allows individual products to be accessed from the archive. This is the long-term data store, which may take the form of a tape and hence be quite slow.

Auto Size Display

This feature will auto-fit the display longitudinal axis to fit the product length, regardless of its length.

Process one line in n

For machines with limited processing capabilities this option will reduce the workload, by not passing every scan line, but every nth scan. This is useful for reducing the network traffic to Client Displays.


Lag Latest Product by n

This feature permits you to show real time product displays of the current product (set to 0) and the previous product (set to 1), or the one before that (set to 2). All three displays will be updated continuously as new products arrive.

Global

This feature enables a number of data sources to be made global and allows multiple displays to be updated simultaneously using a single command.

Data Type

This defines the type of data as either

Product Data

Selecting this option displays the available product data. The source of this data is selected in the Data Source section.

Product Statistics

Product statistical data is data that has been generated on the whole product data. Selecting this option will provide access to the stored statistical data.

Product Selection

This function allows the user to search for particular products in the database or the archive.

Show All Stored Products

This option displays all the stored products in the database or the archive.

Reduce products by Date/Time OR Name Selection

This option allows the user to enter either:

Name

Searches for product names containing the specified search text.

Data and Time

Searches for products before of after the specified date.

Reduce products by multiple Date/Time and Name Selection

This option allows the user to enter both a name and time/date and refines the further.


Advanced

This option allows the user to specify SQL Commands using the SQL Syntax for Microsoft Access ® Databases.

For ease of use it is recommended to select first the “Reduce products by Date/Time OR Name Selection” then select the Advanced option. This will cause the Landscan WCA software to automatically generate the fixed SQL statement for the ORDER BY field. It is also possible to copy directly the following statement into this field.

[TimeEnd],[ProdNo],[MillStation],[ProductType],[ProductPass]

The search parameters must always be in square brackets [ ], examples of searchable fields can be found below. When specifying the WHERE field it is vitally IMPORTANT to add a statement to select only products from the current station. This should be of the form

AND [MillStation] = x

Where x = (station number – 1)

When the OK button is selected the search is automatically performed and the result displayed in the select database product field.


Example 1:

To search for Products having a width between 3250mm and 3300mm, at station 1, the following SQL String should be used for the WHERE field:

[Width] < 3300 AND [Width] >=3250 AND [MillStation] = 0

Example 2:

To search for Products created before 15:05:35 on 10 October 2005 with a length less than 15000mm at station 2, the following SQL String should be used for the WHERE field:

[TimeEnd] <= #10/10/2005 15:05:35# AND [Length] < 15000 AND [MillStation] = 1

Examples of searchable fields:

Product Name [ProdName] Product Start Time [TimeStart] Product End Time [TimeEnd] Product Length [Length] Product Width [Width] Pass Number [ProductPass]

Examples of logical operators:

AND OR LIKE

Select Database Product

This lists the stored products that have met the criteria specified to the Product Locator. The list may take a little time to build if the database or archive is on another networked computer. The Refresh button will update the list.

If reversed product passes are available then there will be a [+] next to the product name, pressing this will list all the pass data that is available.


Reference Archive Product

Any product selected for display can have its thermal data compared to a reference product and the results displayed. This is achieved by configuring the following part of this dialog.

Check the box titled “Compare with reference product”; this gives a list of available reference products.


It is IMPORTANT to understand the distinction of a reference product. This is a product that has been archived into long term storage.

Having selected a reference product this may be changed by using the Select button on the dialog.

You can alter the temperature above which comparisons are made by changing the Threshold Temperature field.

Combined Data Source It is possible to select multiple stations to be combined together; this could be used if multiple Landscan heads are placed across the product to give complete coverage. It is possible to select any number of stations below the current station.

Example:

If Station 3 is selected as the combined sources station, then it is possible to combine it with Stations 1 & 2, but not Station 4.

When Combinierte Quelle is checked the select sources dialogue is opened, this is where the stations to be combined are selected. The following options are available for the combined data station:

Don’t Normalize

Normalize Line Tracking

Normalize Measured Length

Normalize Configured Length

Select Configuration

As with any data source it is possible to configure Zones & Input Channels for a Combined Data Source. These are mapped from the physical data sources that are used to make up the Combined Data Source. The zones and input channels should be configured on the individual data sources using the Control Zone, Local Zone, Analog Input and Digital Input dialogues. The Multiple Configuration dialogue is then used to map the physical zones and input channels to the zones and channels of the Combined Data Source. If a zone profile display is created for a Combined Data Source it will show the mapped zones from the physical data sources.


Configure Line Data

It is possible to configure the 1000 samples of the scan line from each of the physical stations into the scan line of the Combined Data Source.

Left Sample Range

This is the scan line of the physical station (1-1000 sample represents the complete scan line).

Right Sample Range

This is the scan line of the combined data source (1-1000 samples represents the complete scan line).

Reduction Processing:

This option selects how the reduction from 1000 samples to the required number of samples. The available options are:

None

Average

Maximum

Minimum

Overlap Area Processing:

If the physical scan lines are configured overlapping into the combined data source scan line this option selects the processing applied to the overlapping section. This can be used to overcome small calibration differences in Landscan heads. The available options are:

Average

Minimum

Maximum

Example:

Three stations (Stand 1, Stand 2 and Stand 3) configured as a Combined Data Source (Stand 3).


For each station the complete scan line (1-1000 samples) is mapped as 400 samples in the combined data source.

The reduction is configured to average the samples to generate the 400 sample points.

The overlap areas (A & B) are configured to be an average of the overlapping values.

Display Types

Profile Display This plots a simple line plot of the scan line of temperature Vs scan width. The current product length is also included on the display. The Overwrite mode is available with this display. An example of a profile display is: -

The background and trace color is modified using the general colors palette.

Map Display

There are two modes of operation of the map display Relative and Absolute modes; the type of mode defines how the colors will be displayed. Color palettes are available for each individual mode.


Absolute Mode

The Map mode displays the temperature samples in a scan as points of color arranged in a vertical line. A scale on the side of the map defines the temperature ranges represented by each color. The horizontal scale of the map display is graduated to indicate the distance or time of the lines displayed within a set column width.

Relative Mode

A center Target Temperature and the Tolerance band of values around that point are displayed in a pre-defined color. Values below the range are shown in cool colors (in the default), those above in warm colors (default). The relative mode is valuable to show the proportion of a target within a particular temperature band.

An example of a Map display:


Control Zone Profile This plots the control zones along a time axis, against a temperature vertical axis.

The individual trace colors are modified using the color key palette.


Local Zone Profile This plots the Local Zones along a time axis, against a temperature vertical axis.

The individual trace colors are modified using the color key palette.


3D Map This display is very similar to the Map except that the temperature values as well as having color are drawn with height. The effect is an isothermic surface color plot. All the options available for the Map are available for this display.


Zones & Alarms This is a tabular display of the control zones, local zones and alarm status.

LPU/LSC Inputs This is a tabular display of the status of each Analog and Digital Input to the selected LPU/LSC Processor.

IMAGE REQUIRED


Product Information This lists the product name, data, time and the data from the PDI message (if available). The PDI data is only updated if the user has configured the naming of the product from PDI messages, in the Product Configuration option.


Cursor Data All the cursor data is displayed by color key. The Cursor Display are often used in conjunction with other displays to indicate the cursor position.


Alarm Outputs The current status of the alarms is displayed in a Red/Green - On/Off readout.


Analog Inputs The current status of each of the analog inputs is plotted along a time axis, against a user defined vertical axis.

This example shows an analog speed input scaled for from -2500mm/sec to 2500mm/sec.

Digital Inputs The current status of each of the digital inputs is plotted along a time axis, against a user defined vertical axis.


Envelope Profile This plots the maximum and minimum temperature range of every sample in the scan line.

The colors can be altered using the general colors palette.

Product Width The width of the product as measured between the hot edges is displayed against time. The Product determination, dialog items must be configured to locate the edges.


Product Walk The movement of the product from the centerline of the scanner is displayed against time. The Product determination, dialogue items must be configured to locate the edges.

Data Diagnostics This is a Diagnostics tool for Land Engineers.


Delayed Profile

Longitudinal Profile This is a profile display along the length of the product as opposed to across the scan angle. The position of the cursor on a map display is used to select the position of the longitudinal profile in the width direction.


Vertical Map This is similar to the standard map display; however it is rotated with scan angle on the x-axis and distance/time on the y-axis.


Statistical Distribution The Statistical Distribution performs a Gauss Curve function on the temperature data of the selected Data Source. The function is performed on all the temperature points within the detected product of the Data Source unless another display (e.g. map) is zoomed onto the Data Source then the function is performed on only the zoomed area.


Local Profile The Local Profile displays the profiles configured within the Data Processing – Local Processing - Local Profile Processing function.

Storage – Management (Alt-S and M)

The system database holds the most recent product data, by following the rules defined below. A product wrapping mechanism is employed to manage the data, a FIFO (First In/First Out) method is used so that the oldest data is removed from the database. In this way several days or weeks of data can be made available (depending upon the storage rate and disk drive capacity). Products are added to the database until it reaches the capacity defined and then the oldest product is removed from the database to make room for the new product.

General

240 • Storage – Management (Alt-S and M) LAND Instruments International Ltd. LANDSCAN WCA

Individual modes of storage can be configured on a measurement station basis.

System Storage Enabled

This activates storage for all of the enabled measurement stations.

When the database size becomes:

This option allows the user to configure the amount of space the database is allowed to use. The size can be defined in terms of:

% of the disk capacity

the number of products

the age of the data.

If the database begins to exceed 90% of the disk capacity then the system will over rule the users rules and begin to remove data from the database.

If the disk capacity is already exceeded when storage is started for the first time then no files are stored.

Take the following action with the oldest products:

Delete the oldest products

When this option is selected all old data will be deleted from the database when the limit of the database size is reached and it wraps

Archive oldest products then delete from Database

When this option is selected the old data will be copied to the archive prior to being deleting from the database.


Archive products direct Delete Oldest Product

When this option is selected all new products are copied immediately to the archive when they are stored. The oldest products will be deleted from the database when the limit of the database size is reached and it wraps.

Some files ( approximately 40 need to be in the database before this function will start)

Storage Location

It is possible to configure as many hard disk drives as physically present within the Data Server to hold the database.

Store To

Primary & Secondary Drive

The database spans both the Primary and Secondary drives.

Primary Drive Only

The database is stored on the Primary Drive only

Primary to Secondary Drive

The database is stored on all drives mapped to letters between the configured default and secondary drives

For Example

Default Drive = P

Secondary Drive = R

Database stored on drives P, Q and R

Secondary Drive Only

The database is stored on the Secondary Drive only

Default Drive

Specifies the drive letter to be used for the database, the drive must be a valid drive on the computer.


Secondary Drive

Specifies the secondary drive letter to be used for the database, the drive must be a valid drive on the computer.

Path

Defines the path to the database, this must be the same for both drives when spanning two drives.

The path must always start with a leading '\'.

It is IMPORTANT to note that for data to be stored for a particular measurement station both System and Station Storage MUST be enabled.


Station


The rules of storage for each measurement station can be configured independently.

Station Number

Selects then measurement station

Storage Enabled

Activates the storage mode selected. It is necessary for both this enable and System Storage Enable on the Storage - Management menu and the General Tab to be checked for storage to be enabled.

Storage mode

Various modes of storage control are available:

Store Products

When enabled all product data that passes into the system will be stored.

Storage Data reduction

The quantity of data generated by the system can be immense when running with several scanners at the maximum scanner speed. In order that data over a longer period of time can be made available in the database, the quantity of data stored can be reduced.

Reduction Mode

This feature allows the selective reduction in data stored by a combination of pass reduction, line reduction, sample and system configuration reduction. The selected reduction can be either of these options or a combination.

Pass Reduction

For products, which reverse, the user can choose to ignore either all forward or all reverse passes.

Line Reduction

The user can reduce the number of scan lines to either: -

Every X Lines.

Every X Seconds.

Every X Meters.

Caution should be used if using Seconds or Meters that the reduction is not such that no data is stored.

DO NOT STORE System Configuration in Data Files

Check the box titled "DO NOT STORE System Configuration in Data Files" to omit the system configuration data from each stored file. This reduces the size of each file by approximately 412Kbytes.


Sample Reduction

The data can be reduced to one in every X samples in a scan line OR to all samples between two sample positions. The one in every X samples is configured on this dialog where as the Advanced option from the Configure menu allows configuration of the sample position limits.

If the user has chosen to reduce the number of samples stored in the Advanced menu then this overrides any sample reduction configured in this menu.

A summary of the selected storage reduction is given at the foot of the dialog box.


Statistics and Maintenance


Statistics The statistics selection of this dialog is used to configure the storage of statistical products.

Enable Statistics Storage

When this option is checked the storage of statistical products is enabled.

Delete the statistics when the database size becomes:

This option allows the user to define the size of the database in terms:

% of disk capacity

the age of the data.

If the database begins to exceed 90% of the disk capacity then the system will over rule the users rules and begin to remove data from the database.

The statistics database is stored in the location configured as the system storage database. A summary of this location is indicated on the dialog.

Maintenance Caution should be used when attempting to use this function. If unsure then contact Land for assistance.

This allows the user to generate or rebuild the catalogue of stored files for either the database or archive. In either case the ProductInfo.mdb file (which is the file used to catalogue the database) is generated or rebuilt.

If default settings are being used then for the Database the following database file is generated or rebuilt.

\LandscanDatabase\productInfo.mdb.

For the archive process the following file is generated or rebuilt.

\LandscanArchive\productinfo.mdb.


To rebuild either database you must disable both Database and Archive storage. Then select the button to disconnect and then refresh the database. For large databases and archives this rebuild will take some time and it is not recommended that it be performed during intensive system processing. The user should view this as a maintenance task.

If a new location has been specified for the databases it is necessary to generate a new database.

Diagnostics – Encoder Calibration (Alt-G and E) The Encoder Calibration functionality is only relevant when the software is used in conjunction with a Landscan Batch Processor equipped with an encoder input.


On rotary processes ( LSC Batch Processors only) that require rotary geometry correction to product data it is necessary to provide an encoder input position signal and a rotation index input to the system.

The encoder input provides a rotary position signal for the processor and the digital input provides a rotary index trigger to indicate when a complete 360º rotation of the machine has taken place.

The encoder input requires a calibration to calculate a correct value for the encoder counts in relation to degree's of rotation of the process.


This calibration is performed during the operation of the rotary machine, when the user clicks the start button, the Landscan WCA software will wait for the next Digital Start signal from the Landscan Batch Processor. After this the system waits for next Digital Start signal (indicating that a complete rotation has taken place), during which time the system records the number of counts from the rotary encoder. When the second Digital Start signal is received the Counts per Degree value is calculated.

While this process is taking place the user is informed of the current status.

Waiting Calibration

The processor has not been calibrated and requires a calibration to be initiated.

Waiting Start Signal

A calibration is in progress and the processor is waiting for the first digital input start signal.

Waiting Stop Signal

A calibration is in progress and the processor is waiting for the second digital input stop signal.

Calibration Completed

A calibration has been successfully completed with the calculated Encoder Counts/Degree value displayed.

Diagnostics – Rotary Triggers The Rotary Triggers Configuration functionality is only relevant when the software is used in conjunction with a Landscan Batch Processor equipped with an encoder input.


On rotary processes there are a number of stations that must be defined for the system. A station relates to the number of individual products present in the process for a full rotation of 360 degrees.

An encoder input to the system provides a rotary position signal for the processor. Following a calibration of the encoder input the system can determine the current angle of the process. This is displayed in the Current Angle box of the Rotary Triggers dialog. Refer to Encoder Calibration for information relating to calibrating an encoder used with the system.

286 • Security Menu LAND Instruments International Ltd. LANDSCAN WCA

For each station a trigger angle must be defined which is used in the Processors Product Detection functionality. The number of stations should be defined on the Processor Product Detect Page.

By manually positioning the rotary process at the desired station trigger point the current angle can be stored as the product trigger point by pressing the relevant station button.

In addition to the station trigger points the product length needs to be defined in degrees of rotation. This can be configured using the Product Start, Product End and Product Length buttons.

The process should be manually positioned at the start of a product and the Product Start button pressed. Then the process should be positioned at the end of the product and the Product End button pressed. If the product start and end values appear correct then the Product Length button should be pressed to calculate the product length using the stored start and end angles.

Refer to the Processor Product Detect Page for further information relating to product detection.

300 • Communications LAND Instruments International Ltd. LANDSCAN WCA

Communications

Communications Interface The Landscan WCA software supports relatively slow serial links via the RS232 interface (of the Data Server computer) or an Ethernet interface supports TCP/IP. Either interface supports access to the following data: -

• Zone Data

• Statistics Results

• Product Width, Walk and Edges

And control….

• Product Description, via PDI messages

• Product Speed

• Display Configuration

The Ethernet functionality is intended for users who have installed a local area network and can manage their own site and who fully understand the intricacies of implementing TCP/IP applications.

Both slow and high-speed communications support the message interface definitions described in the following sections. All messages are constructed using simple text and have similar logical format. In both instances the Landscan WCA Data Server acts as a slave, performing actions and responding to instructions only when prompted to do so by the host computer, or master.

For the Ethernet interface, the Landscan WCA Software creates a Server Socket and the host computer, as a client, logs into it.

LAND Instruments International Ltd. LANDSCAN WCA Communications • 301

Typical Implementations The Landscan WCA Data Server adopts a Master/Slave relationship with other communicating devices and will always be the Slave, only responding to messages when prompted to do so by the Master.

The users own computer equipment or process computer must act as the Master device by initiating ALL transmissions. Messages sent by the Master are referred to as commands, whilst replies from the Landscan WCA Data Server are referred to as responses and for every command there will be a response.

A four-character string preceding the information where the first character of a command is a 'C' and the first character of a response is an 'R' identifies all messages. Thereafter follows the content of the message. The SPACE character must be used as a delimiter between each parameter that constructs the message and the CARRIAGE RETURN character acts as a terminator and must signify the end of the message. All message characters are ASCII values.

The Landscan WCA Data Server will reject any messages that do not comply with the message interface definition. It is the responsibility of the user, when interfacing to the Landscan WCA Data Server, to ensure transmissions were received intact and interpreted as intended and that parameter changes have been accepted.

Reply Code All responses from the Landscan WCA Data Server return a reply code, which conveys information to the user about the health and system integrity.

The reply code can be returned in response to any command. It will indicate that the message transmission received by the Landscan WCA Data Server was not corrupted, the settings (if applicable) are valid and the parameter changes (if necessary) have been implemented successfully in the Landscan WCA Data Server.

The reply code is also returned when data is requested. It indicates that the accompanying data returned in this message is current and good; otherwise the code will reflect a known event or condition that can be diagnosed by the user as the reason for unacceptable data.


Parameters The Landscan WCA Data Server validates the parameter settings on receipt to be an integer, i.e. a whole number, a floating-point value, i.e. with a fractional part or a character string of length. The whole message is rejected if either the format or the range of any individual parameter is invalid. The message is also rejected if the number of parameters is incorrect, either too many or not enough are received.

Ethernet TCP/IP Implementation TCP/IP is implemented in the Landscan WCA Data Server using the concept of a socket interface. The Landscan WCA Data Server acts as a server, passively listening for a connection on a selected port. The client can then at any time actively open the connection and establish a channel for communications. Messages can be exchanged whilst the interface remains open.

If the Landscan WCA Data Server is removed from service requiring the power to be switched off or if there is a mains supply failure then the client must attempt to re-establish that connection indefinitely until the unit is brought on-line again.

If the client detects an irrecoverable situation where the Landscan WCA Data Server does not respond to messages the connection should be properly closed before retrying. If the client itself decides to terminate the relationship then it must properly close down the connection. When communications with the Landscan WCA Data Server are suspended without closing the connection then it is possible that reconnection will not be achieved.

Protocol Definitions The following lists of commands (and appropriate responses) are applicable to both TCP/IP and RS232 communication links.

If an invalid command is retrieved then the following message will be returned. This is regardless of the message transmitted.

'RPDI 2<CR>'

A space character (ASCII 32) separates the 'RPDI' and '2'. This is terminated by a carriage return.

If a valid command is received and the license does not support this command then the following message will be returned.


'RPDI 3<CR>'

A space character (ASCII 32) separates the 'RPDI' and '3'. This is terminated by a carriage return.

An exception to this is if the incoming message is less than 5 characters in length. In this particular case an event is logged to the Landscan WCA event log.

Communications License Options A RS232 or TCP/IP connection can support the following messages.

• PDI – Product Definition Information message.

• SSM – Get Statistics results message.

• CZD – Get Control Zone Data message.

• CPS – Set Product Speed message.

• LDS – Load Display Sheet message.

• RSS – Get System Status message.

• WWE – Get Width Walk Edges message.

The support of these messages is dependent on the Landscan WCA license. There are four different types of communications license.

• TCP/IP – All messages, including live data.

• TCP/IP – All messages, except those with access to live data.

• RS232 – All messages, including live data.

• RS232 – All messages, except those with access to live data.

Product Definition Information (PDI)

PDI Command The PDI message received over the TCPIP/RS232 link must be in ASCII and of the following structure. All fields must be included in any message sent.

Field Name Maximum Field Length (8 bit characters)

Maximum Field Value, after conversion from ASCII.

Command PDI 4 Always CPDI

StationNumber 2 32

ProductName 50

ProductWidth 10 2147483647

ProductDirection 1 1 or 0

ProductType 50

IsAProduct 1 See Notes

StorageOn 1 1 or 0

ProductString1 50

ProductString2 50

Each message must be terminated with a CR (ASCII 13).

The communications process will check for space (ASCII 32) delimiters between each of the fields, which comprise the message. If the process detects fields greater than their specified maximum length then the whole message will be ignored. If the process detects that any of the fields to be greater than their appropriate data type (e.g. Product Width > 2,147,483,647) and the whole message will be ignored. When an error is detected then an event will be logged.

ProductWidth,ProductLength

These parameters are an integer value of the current display distance units (mm, meters etc..)

ProductTargetTemp, ProductTargetTempMin, ProductTargetTempMax

These parameters are the expected temperature limits of the product. They are always an integer value of the current temperature scale (Celsius / Fahrenheit).

ProductMaxDisplayTemp, ProductMinDisplayTemp

These parameters are the temperature ranges of the current displays. They are an integer value of the current temperature scale.

ProductDirection

This parameter ss the direction of movement of the product

ProductDirection = 1 the product is moving in a forward direction

ProductDirection = 0 the product is moving in the reverse direction.


IsAProduct

This parameter is used to define the start and end of the product.

IsAProduct = 1 Start Product

IsAProduct = 0 End Product

It should be noted that it is necessary to define both the start and the end of a product, as it is not sufficient to define the start of a new product and assume that this will generate the end of the previous product. This will result in missed products.

It is also possible to set the IsAProduct to a value greater than 1. This is recommended in the case of a continuous process that is to be divided into products using PDI Control. This is necessary as sending an end product (IsAProduct = 0) and start product (IsAProduct = 1) in quick succession may result in the end product being missed. The difference between the value of IsAProduct and 1 will be used as a counter for the number of scan lines between the end of the product and the start of the new product.

For Example PDI Message WCA Action

IsAProduct = 5 End Product ..

.. Wait 4 Scan Lines ..

.. Start New Product

StorageOn

Defines the status of the product storage

ProductStorage = 1 product storage is active

ProductStorage = 0 product storage is disabled


The system expects that a message will be received for each station connected to the system prior to the actual product arriving at that station. These messages will not be concatenated together.

An example message would be: -

1 Mill Station number is invalid.

2 Mill Station number is valid. No control zones configured.

3 Mill Station number is valid. Error in Zone Data.

4 Mill Station number is valid.


No product currently detected under scanner.

Last good values returned.


No product detected yet.

Null control zone data values returned.

The Zone Data value is padded with leading zeros up to the 4 character maximum. Therefore an example temperature of 900 is given as '0900'. If no control zone is configured the value is '0000'.

If the station number is invalid then all zone data values are zero.

All fields are delimited by spaces (ASCII 32). The full message is terminated by a carriage return (ASCII 13).

An example response message would be: -

'RCZD 1 4 0000 0900 0000 0333 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000<CR>'

This is the control zone data for Mill Station 1. There is no current zone data so the last good values are being returned. This shows only zones 2 and 4 being configured.

Statistics Data (SSM) This command requests the current statistics results for a particular Mill Station. The results are the configured segment results; these are (currently) average, minimum and peak temperature values only.

SSM Command Field Name Maximum Field



Command Statistics Segment Message

The station number is the same value as the station number received in the command.

The reply code can be: -

0 Latest Segment results.


1 Mill Station number is invalid.

2 Mill Station number is valid. No statistics data read.


No new statistics data since last data read.

The segment results are padded with leading zeros up to the 4 character maximum. Therefore an example average temperature of 123 is given as '0123'.

If the station number is invalid then all zone data values are zero.


An example response message would be: -

'RSSM 1 3 0000 0900 0000 0333 0000 0000 0000 0000<CR>'

This is the control zone data for Mill Station 1. There are no new statistical results so the last good values are being returned.

Load Display Sheet (LDS) This command allows an already created display sheet to be loaded. In addition to the received message being of the correct format the following rules apply.

The display sheet must be previously saved in the \WorkSpace directory that, by default, is located under the installation directory.

The computer name in the received message must be a valid and that computer must be running Landscan WCA. It is also possible that the computer may be a client display to the main data server.

Range is -999999.99 to +999999.99 Except when the value is 000000.00 the sign is always specified.

StationNumber

This parameter always has the same value as the StationNumber received in the command.


0 Product Width, Walk, Edges values are valid.

1 StationNumber in the request is invalid.


2 No Products detected yet, returning NULL values.

3 Not currently detecting a product under the Landscan Head, returning the last good values from the previous product.

4 Error in Width, Walk, Edges calculation.

Values returned should be ignored.

Format Code and Meaning

1 Values returned are in millimeters.

2 Values returned are in inches.

ProductName

This parameter is the name used by the Landscan WCA software to reference this product. Field is filled with the value "UNKNOWN" if the ReplyCode is 1, 2 or 4.

FirstEdge, LastEdge, Width values

These parameters have a range of 000000.00 to 999999.99. These values are "padded" with leading zeros to always ensure that each field contains 9 characters. The values are "000000.00" if the ReplyCode is 1,2 or 4.


Walk

This parameter has a value within the range of –999999.99 to +999999.99. These values are padded with leading zeros to always ensure that each field contains 10 characters. A negative value indicates that the Product has walked towards the start of the scan (with respect to the center of the scan), a positive value indicates that the Product has walked towards the end of the scan (with respect to the center of the scan). This value is "000000.00" if the ReplyCode is 1,2 or 4.


The width, walk and edges values that are returned are affected by the scanner configuration within the Landscan WCA software. The scanner type, distance from product and tilt angle (and others) should be correctly configured to give the correct values. The calculations, which take account of these parameters, are only made on system start-up and at the start of each product. This is deemed sufficient because these values are unlikely (once configured) to alter with any great frequency.

Windows XP The default operating system settings prevent access to the Landscan WCA Data Server by the Client PC. The common symptoms of this problem are that the client can find the server in the network, but cannot access the Data Server through the Landscan WCA software.

To resolve this issue it is necessary to manually configure drive sharing on the Data Server and Client PC. The following steps should be performed:

• Enter My Computer

• Right Click on the Landscan WCA Installation Drive (this is C by default)

• Select Sharing and Security

• The Property page of the hard disk will be opened;

Select the option to enable file sharing

Select the option to share this drive

• Click OK

LAND Instruments International Ltd. LANDSCAN WCA Landscan WCA ActiveX Control • 331

Landscan WCA ActiveX Control

Information In order to be able to view live and stored scan data in other applications a Landscan WCA ActiveX control has been developed. This is installed on the hard disk for each type installation and is file LandCtl.ocx.

If an application can accept ActiveX controls then Landscan Control is the Landscan WCA ActiveX control. When used within an application additional programming/development will be required to retrieve data from the ActiveX control, examples are copied to computers hard disk at installation, and these reside in directory \ActiveX Examples. Please contact Land if additional information is required.

PLEASE NOTE:

The ActiveX examples provided can be re-worked/re-engineered without the need for prior agreement from LAND. All examples use the Visual Basic For Applications development environment, which is an incumbent part of the Microsoft Office Suite.

This ActiveX control is under development and provides no user interface. For developers wishing to use the ActiveX control a type library (landctl.tlb) and interface definition file (LandGUID.H) is provided, with additional technical details being available on request.

The readme.txt file in the root directory of the Landscan WCA installation CD provides additional details on this control.

It is not recommended that ActiveX be implemented on a Live Client Display installation, please contact LAND for further information.

332 • Frequently Asked Questions LAND Instruments International Ltd. LANDSCAN WCA

Frequently Asked Questions

How do I calculate the ideal position for my scanner relative to my application?

LAND Instruments International Ltd. LANDSCAN WCA Frequently Asked Questions • 333

The key is to always ensure that you can always cover the widest product rolled plus the maximum expected lateral product walk. This often coincides with the edges of the roller table or similar. Then add ~10% to allow for scanner alignment tolerances to arrive at your final required scanned width, W. Now use the equation above to calculate d, and from this you can arrive at the required 'scanner front window to product centerline' distance.

Note: For an 80° scanner then please substitute 'tan40°' for 'tan30°' and also adjust (d+62) to (d+46) as the center of scanning mirror in 16mm closer to the base of the instrument.

Can you reverse the direction of scanning? Not in hardware. The direction of hardware scan is fixed for all models.

LS Scanner Head

The direction of scan is indicated on the A3 installation sheet near the front of each Head's operating instructions.

LSP Scanner Head

The direction of scan is indicated by an arrow on the top of the scanner head.

However, the Landscan WCA software allows the direction in which the data is presented to be reversed. From the display point of view, the effect is the same as if the scanning direction had been reversed.

How do you know where the scanner is looking? LS Scanner Head

A Laser Alignment Unit is available which temporarily plugs into the Landscan Head.

LSP Scanner Head

All scanners except the LSP5FL are fitted with an alignment laser as standard.

In both cases an eyesafe laser beam is directed down the sightpath and off the center of the rotating mirror. The result is a red laser line, which defines the location of the scan plane on the product surface.


How often should I clean the front window? There is no simple answer to this; it is a function of application environment, installation engineering and air quality, reliability and flow rate. If all of these are relatively good, then a monthly check should suffice. The best approach is to start with monthly inspections and then increase or decrease the frequency as required.

How often should I check the calibration of my scanner? The Landscan Head is a precision optical instrument and Land recommends an annual check of calibration under normal circumstances. However, the answer to this question can often be found within the customer's own QA procedures. They may stipulate for example, quarterly checks and an annual NAMAS certificate.

How much water do I need to cool the scanner and what sort of water do I need?

The cooling water should be clean, filtered instrument water.

LS Scanner Head

Two pairs of supply and drain lines to be fitted – one for the Housing baseplate, the other for the Housing's water cooled walls. Both supplies should be capable of delivering a reliable and consistent flow of up to 200 litres / hour of water at an inlet (to the Housing) temperature of between 10-30°C. It is recommended that the customer fits water flow alarms to each supply line.

(Note: the standard Rugged Housing at the Lehr Exit only requires a single pair of supply and drain lines to be fitted to its baseplate – it does not have water cooled walls.

How much purge air do I need to keep the front window clean? The Fan units should be positioned so that they can draw relatively cool air – preferably from outside the building if possible.

Purge Air – to be supplied by Landscan Fan Unit. Fan Unit installation must be carefully maintained to ensure a reliable and consistent flow of air at an inlet temperature of <45°C under all operating circumstances and during all seasons of the year.


Differential pressure transducers can be fitted to the Housings as an option. This will provide an alarm relay output in the event of loss of purge air to any Housing to which one is fitted.

How many analog outputs can I have from my Processor? LPU_2E

Each analog output card contains 4 analog outputs and an LPU_2E can hold up to 4 of these cards. However, outputs 1and2 are dedicated to remote control of the attached Landscan head's internal scan speed and Emissivity settings.

So, each LPU_2E can be configured to offer 0, 2, 6, 10 or 14 analog outputs for process control, etc.

LSC

Up to 3 Digital/Analog Input and Output Cards (DAIO) may be fitted. Each card provides the following analog outputs, see Processor Input Page for the specification of Analog and Digital Input channels or the Digital Output Processing Page for the specification of the Digital Output Channels.

Output Type No. of Channels Specification Analog 4 0 to 20mA / 4 to 20mA,

- independently software selectable

Digital 4 Voltage-free relay outputs


How are the Processors analog outputs configured to meet my application needs?

The analog outputs are configured via a zone model with the control zones dialog. Zone configuration includes zone numbers, zone width, time function, statistical processing function (max, min or average) and zone location.

Each zone can be individually configured to track the hot product edges or stay fixed to the plant (you could have a mixture of 6 tracking and 8 fixed zones, for example), start and end of zone location (can be relative in percentages or can be fixed with reference to the either hot edge or the center of the product).

When a LSC Processor is used further options for Analog Outputs are available, see Analog Output Configuration.


Are there any limits on the cable distances between networked components of a Landscan System?

The recommended maximum cable distance for a CAT5 Ethernet cable is 100m; this can be extended by using a repeater such as a network switch. Cabling is governed by the International standards for Ethernet and Fast Ethernet.

I have excessive scale on my products. How do I remove it from the data? Refer to the Line Scanner Dialogue Signal-conditioning feature.

There is excessive electrical, or product Emissivity 'noise'. How do I remove it from the data?

Refer to the Line Scanner Dialogue Signal-conditioning feature.

What options are available with the Landscan WCA license? The Landscan for WCA license is applied to either a Data Server installation or Demonstration installation. No changes can be made to the demonstration license.

The Data Server license allows configuration of the following system parameters.

• Number of Client Displays.

• Number of Connected LPU/LSCs.

• Number and type of Communications connections.

• Number of live ActiveX interfaces.

Each of these parameters controls a different part of the system they are not dependant on each other.

The limits of these parameters are: -

• Number of Client Displays. Maximum of 3.


• Number of Connected Processors. Maximum of 8.

• Number and type of Communications connections. Maximum of 1 (either TCP/IP or RS232).

• Number of live ActiveX interfaces. Maximum of 4.

The changing of these parameters potentially increases the workload of your Landscan system and therefore you should contact your Land representative for details of any license upgrade.

How do I replay data files from an older version of software ?. When a version of Landscan WCA is upgraded the first time the new version is run all stored files are converted to be compatible with the new version. This process will lengthen the time it takes to start the software.

The following introduces the Storage Import / Export Function which can be used when the software is running to replay data files from a previous Landscan software version.

The Landscan WCA software uses the Archive for the replaying of data files stored using an older version of Landscan software. The database (configured from the Storage menu) only stores and replays data stored with the current version of Landscan WCA.

When attempting to replay files from an older version then they must be copied into a directory structure that follows a specific format. At this point it is best to review the System File Structure section.

The files should be copied from their source directory into the ImportFiles directory, which should be located under the main archive directory.


You should use the Import / Export Data Files function to copy files into the correct directory. This will create the ImportFiles directory if it does not already exist.

When the files are successfully imported. Go to the Statistics and Maintenance dialogue and refresh the archive database.

It should now be able to read the files from the older version in your current version of the Landscan WCA software. When selecting a file in the select data source dialog choose archive as the source.


How can I tell what the current scanner speed is from the Landscan WCA system?

In order to do this the scanner, and associated LPU/LSC should be correctly connected to the Landscan WCA system. This can be easily observed by the icons on the status bar.

Then perform the following: -

Open the Diagnostics – Scanner Dialog

Or

Data Diagnostics Display

• Select a new Display.

• Select the Data Source to be a new one of type Real Time Scanner for the appropriate measurement station.

• Select the Display Type as Data Diagnostics.


How do I change the Data Server computer that my Client Display connects to? This involves modification of the system registry on the Client Display computer. This should only be modified for users experienced in using the system registry.

When performing this change ensure that the Landscan WCA software is not running on the Client Display computer.

1. On the Client Display computer.

2. Stop the Landscan WCA software.

3. Run the Start menu select the Run option. Enter Regedit in the box and press OK.

4. Select the following registry path.

My Computer\HKEY_CURRENT_USER\Software\Land Infrared\Landscan\Hub\Configuration

5. Edit the following registry entry so that its value is the name of the new Data Server computer you wish to connect to.

MasterComputer.

6. Exit the registry editor and restart the Landscan for Windows NT software on the client display computer.

DO NOT MODIFY ANY OTHER REGISTRY VALUES.


What does the error message “The Master System Is Not Available” mean on my Client Display Installation?

These error messages are normally generated when a Client Display cannot correctly connect to the Data Server. Typically this may be because the Landscan WCA software is not running on the Data Server computer.

Please ensure that the Data Server and Client Display are configured as per the Data Server configuration for Client Display Access.

What do the following network 'ping' messages indicate is the fault in my Data Server to LPU/LSC connection(s)?

Destination host unreachable

This could be due to:

1. The IP address that has been used is invalid for the range of available IP addresses. For Example:

The DataServer is configured to IP address 10.1.10.10 with a sub-net mask of 255.255.0.0 and the LPU/LSC is at address 10.1.10.160, BUT the IP Address that has been used is 11.1.10.160.

2. The LPU/LSC unit has not connected to the computer properly. To rectify this perform the following:

• Exit the Landscan WCA software, if running.


• Leave the computer powered and logged onto Windows.

• Remove power to the LPU/LSC unit. Wait for 1 minute.

• Reconnect power to the LPU/LSC unit. Wait for 2 minutes.

• Retry the network ping.

• Restart the Landscan WCA software.

Request timed out

The IP address that has been used is valid for the available ranges of IP addresses but there is no communications link between the DataServer and LPU/LSC. Check the following: -

• The LPU/LSC is switched on.

• The IP address that has been used is the IP address of the LPU/LSC unit. Use the LPU/LSC configuration software to verify this value and retry.

• The cabling between LPU/LSC and computer is valid. If using a network switch check that this indicates connection between the computer and LPU/LSC. If using a direct connection ensure the twisted pair cable contains a 'cross-over'.

What process do I need to go through to name my products using PDI? Look at the communications section on the on-line help.

This details the communications messages that can be used in communications with the Data Server. This is communications to the Data Server and not the LPU/LSC unit. All messages are supported by either TCP/IP communications or RS232 communications. The only way to provide product names is via communication to the Data Server.

The section in the on-line help which details the message used in naming a product is PDI COMMAND.

If you review that section it details the message format to be used. In particular it refers to a field called ProductName. This is the field that should be used to name the product. (The naming convention differs from the DOS version of the Landscan software and is now deemed to be more generic).


To simply name each of the products send the following recommended message across either a TCP/IP link or RS232 link to the Data Server. This is an ASCII string.

CPDI 1 PRODUCTNAME 0 0 0 0 0 0 0 0 1 NA 1 1 NA NA<CR>

Where: -

• PRODUCTNAME is changed to suit your name.

• The eight '0' following the PRODUCTNAME are fields ProductWidth through ProductThickness.

• The first 1 is field ProductDirection, which is 1 to indicate a forward product.

• The second and third '1' are the IsAProduct and StorageOn fields. These indicate that the next product is to be displayed and stored by the Landscan WCA software.

• The 'NA' fields are the ProductType, ProductString1 and ProductString2 fields. 'NA' is not applicable.

• An ASCII space character separates each field and the message is terminated with a CR.

To enable the Landscan WCA software (at the Data Server) to receive communications messages you will need to have an appropriate license. Go to the Configure - Communications menu. If you have the communications licensed then the Number of Communications Connections will be 1, if not it will be 0.

The dialog then allows you to configure the type of communication connection, either RS232 or TCP/IP.

To enable you to see whether you are receiving a valid message use the Diagnostics button on the Configure - Communications dialog. This displays a monitor window.

Having received a valid message you need to configure the Landscan WCA software to use the name you sent. Go to Configure - System Dialogue and the Product Tab. To use the name from the PDI message then check the PDI Control via Communications box.

When using PDI to name products, when do I send the message to ensure that the product is named correctly?

In general terms the message needs to arrive at the Data Server computer anytime prior to the product entering the area under the scanner.

Obviously there is processing time required in the Data Server computer from receiving the message to being able to name the file. This is not a defined period of time because it depends of Data Server computer specification and that computers


workload (amongst other things). It is recommended that you attempt to ensure that the message is sent to the Data Server computer at least 5 seconds before the product passes under the scanner.

If the message does not arrive before the product passes under the scanner then you will see the following event in the Event Viewer.

Did not receive product name via PDI.

If I have more than one scanner connected to my Data Server, how do I name the products at the individual scanners ?

With reference to the following FAQ: What process do I need to go through to name my products using PDI ?

To simply name each of the coils send the following recommended message across either a TCP/IP link or RS232 link to the Data Server computer. This is an ASCII string.

CPDI 1 COILNAME 0 0 0 0 0 0 0 0 1 NA 1 1 NA NA<CR>

In the above message:

CPDI is the command used to identify message type. This is followed in the ASCII string by a space. After that is the field StationNumber, which is set to '1' and immediately followed by an ASCII space.

The StationNumber is how you define which scanner you want that message to apply to. The first scanner connected to the Landscan WCA Data Server is StationNumber 1, the second is StationNumber 2 etc….

You cannot concatenate messages together; the Data Server expects an individual message for each scanner, also the Landscan WCA Data Server transmits a reply to all messages that are sent.

For Example:

To name two products under different scanners connected to the Landscan WCA Data Server.

Message 1 to Data Server

CPDI 1 ABDC1234 0 0 0 0 0 0 0 0 1 NA 1 1 NA NA<CR>

- This names the next product under scanner 1 ADCD1234.

Reply from Data Server


RPDI 0<CR>

Message 2 to Data Server

CPDI 2 EFGH6789 0 0 0 0 0 0 0 0 1 NA 1 1 NA NA<CR>

-This names the next product under scanner 2 EFGH6789

Reply from Data Server

RPDI 0<CR>

The above message format is defined in the on-line help. Section PDI COMMAND.

When using the ActiveX control to view Stored Data in Excel, what do Mill Number and Pass Number refer to?

On the example spreadsheet Stored Data.xls: -

The Mill Number is the same as the Measurement Station number in the Landscan WCA software.

For example: -


If you have a Landscan WCA Data Server connected to 2 LPU/LSCs you would have two Measurement stations and the spreadsheet would give access to the stored data from two Mills.

NOTE:

This spreadsheet is just an example. If you find the text difficult to use or understand then please feel free to change it.

The Pass number is only really applicable to processes in which a product would reverse under a scanner.

For example: -

A reversing stand in a hot strip mill, the same product would pass under the scanner (in both the forward and reverse directions) a number of times. Therefore a product would have a number of passes in each direction.

If the product only passes once under a scanner in the forward direction, it will have a direction of FORWARD and a Pass Number of 1.

I have changed the Login Name and Password of my Windows NT user account and now the Landscan software will not work?

This is because the Landscan WCA software uses certain Windows registry entries that reside under the registry key:

HKEY_CURRENT_USER.


Each user of a computer has his/her own set of unique registry entries under this key and if you change the login name you do not have access to another users entries.

To get the software to work you should re-install the Landscan for Windows Software to the same directory as the previous install. This will create a set of registry entries for this user login and the system will work as required.

How do I obtain additional communications message diagnostics? By default this function should be enabled. If it is not enabled then you have the following options.

• Contact LAND for the password required to enable this option and details of the procedure to follow.

Or

• Exit the Landscan software.

• Open the registry editor.

• Go to registry key HKEY_CURRENT_USER\Software\Land Infrared\Landscan\commtest\Configuration

And add a DWORD key called AllowDiagnostics.

Set this value to 1 for additional diagnostics.

• Close the registry editor.

• Restart the Landscan software. The additional diagnostics will be available by clicking on the message in the communications diagnostics window.

I have an Offline Analysis Installation and I am trying to replay data files from a Data Server Installation, with 4 scanners, but can only see data files for the first two scanners?

The reason for this is that the number of LPU/LSC units that the Offline Analysis installation can support is set to a lower value than the Data Server Installation.

Even though the Offline Analysis installation does not connect to any LPU/LSC units it is necessary to configure the number if LPU/LSC units correctly on the Configure System Dialogue, Process Tab, in order to be able to read the required data files.


My scanner has been automatically set to “Disable Scanner for Maintenance” This error is indicated by the Scanner Head Indicator in the Status Bar is colored yellow.

This error occurs when the Landscan Head configured within the LPU/LSC Processor is not recognised by the Landscan WCA Software.

NOTE:

If you enter the Configure – System, Line Scanner Tab to check the status of the Landscan Head, the configuration of the Landscan WCA software indicates a generic scanner selection. However the configuration of the LPU/LSC is not overwritten unless the OK button is clicked on the Configure – System dialogue. If you suspect that this problem has occurred it is recommended that the cancel button is used to exit the dialogue.

If the Landscan Head is not recognised you should contact LAND Instruments who will supply an updated Scanner Head Database, if required.

Updating Scanner Head Database

How do I update the Landscan WCA Scanner Head Database? • Exit the Landscan WCA software.

• Open Windows Explorer

• Copy the new Scanner Head Database File (ScanHeadsInfo.mdb) to the \ScannerHeads folder in the Landscan Installation folder. Overwriting the existing file.

• Close Windows Explorer

• Restart the Landscan WCA Software

• Enter the Configure – System Dialogue, Line Scanner Tab and ensure that the Landscan Head has been recognised by the Landscan WCA Software. If this is true, uncheck “Disable Scanner for Maintenance” – if not contact LAND Instruments for further information.

So for storage reduction of a line stored every 5 seconds and 1 in 5 samples across the each stored line, the reduction value would be 24.

Storage Space is filling or is full This message is for information only.

An event message of the following form :

Starting to remove oldest product.

Indicates that the configured storage space is full and old product files are being deleted to make space for new ones.


Using drive C:\ for storage.

Indicates that the Landscan WCA storage functions are now using this disk to store product data. This event can be generated at first system power-up and each time the storage swaps disks when storage is spanning two drives.


Deleted directory D:\LandscanDatabase\1999\168

Indicates that the Landscan WCA storage functions have just deleted this directory. This has been deleted as a result of the software deleting old files to make disk space available for new ones.

Communications Connection Open / Close This message is for information only.


An event message of the following form

Landscan Server Port 2011 Created.

The Landscan WCA software has created a TCP/IP Socket at Port 2011. This is to allow communications with external plan computers.

The Landscan WCA software is now the Server to that TCP/IP Socket. Any external plant computer can connect as the client to this Server and connect to this socket.

Landscan Server Port 2011 Disconnected.

The Landscan WCA software had created a TCP/IP Socket at Port 2011. This was to allow communications with external plant computers.

The Landscan WCA software is now disconnected from this TCP/IP Socket.

Landscan Server Port 2011 Reconnected.

The Landscan WCA software is reconnecting to the TCP/IP socket created at Port 2011.

RS232 Port Connection Errors The Landscan for Windows NT software is unable to connect to the RS232 COM Port as configured in the communications dialog.

Remedy RS232 Port Connection Errors Ensure the COM Ports are enabled in the computer BIOS.

If they are set, in the BIOS, to AUTO then try setting them to the first serial port to COM1, Address 3F8, IRQ 4.

Check the ports configuration in the Windows NT Control Panel. Configure COM1 to the same parameters configured in the BIOS.

Communications Message Length Error The message received from an external plant computer is either too short or too long.

All messages start with a 4-character command code followed by a space and parameters. So any message which is less then 6 characters in length is invalid.

A message being too long is dependent on the message format itself.

Remedy Communications Message Length Error Review the length of the message received by using the diagnostics option from the communications dialog.


Then compare this to the message format you are trying to use.

If the communications is via an RS232 link and the message received contains invalid characters then review the configuration of the port baud rate, parity, number of data bits etc.

No Disk Space to Archive Products The disk you are attempting to write archive products to is greater than or equal to 90% full and therefore no further products can be archived.

The only remedy to this is to free disk space.

Creating New Database This message is for information only.

Indicates a new catalogue database has been created.


For product storage this is file ProductInfo.mdb, which resides in the directory specified on the General property pane of the Storage – Management dialog.

For statistical results storage this is file StatisticInfo.mdb, which resides in the directory specified on the General property pane of the Storage – Management dialog.

For product archiving this is the file ProductInfo.mdb, which resides in the directory specified on the Archive - Configuration dialog.

LPU_2E Out Of Service The TCP/IP (Ethernet) link to the LPU/LSC has been disconnected.

This event can be generated in the following scenarios: -

The software has successfully disconnected from the LPU/LSC (IP address in event text) during a software shutdown.

The TCP/IP (Ethernet) link between the LPU/LSC and the Data Server computer has been broken. Either some part of the cabling has been removed or the LPU/LSC unit has been powered off. In this scenario it is likely that the following events will be generated at the same time.

Event Number 10054 – TCPIP Receive Error.

Event Number 10054 – LPU2E Receive Error.

The IP address specified is invalid and no LPU/LSC can be found to correspond to that address.

Remedy LPU_2E Out of Service. If the event was generated as part of a software shutdown then it is for information only.

If this event is generated on system power up and it is not possible to perform a network PING to the IP address of the LPU/LSC unit then the following should be checked:

• Cabling between computer and LPU_2E.

• IP address of the LPU/LSC unit is correctly entered in the Equipment Property Page of the Configure - System dialog.

• Check that the LPU/LSC unit has the correct IP address and subnet mask setting. (using the LANDSCAN Processor Configuration software)


• Check that the LPU_2E unit in question is powered on.

If the event is generated whilst the system is running then: -

• Check the network cable between the computer and PU/LSC.

• Check that the LPU/LSC unit in question is powered on.

• Check that a network PING can still be performed.

LPU_2E In Service This message is for information only.

The system has successfully connected and begun to upload data from the LPU/LSC.

Scanner Temperature is high. If the event message text is of the type:

Scanner temp at warning level: 50

Then the ambient internal temperature of the scanner has been detected as very high.

If the event message text is of the type :

Scanner temp too high: 70

Then the ambient internal temperature of the scanner is too high.

Remedy Scanner Temperature is high If the event message text indicates a warning then the scanner is still operating ok. Check the cooling water supply and the air purge to the scanning head.

If the event message text indicates that the temperature is too high then the internal temperature of the scanner has exceeded its maximum temperature; the thermal data from the scanner may no longer be in calibration.

The scanning head may become permanently damaged if the temperature rises any further.

The scanner head temperature can be monitored from the Diagnostics - Scanner dialog.

It is recommended that the scanner is returned to Land Instruments International for re-calibration and test.

Check the cooling water supply and the air purge to the scanning head.


Different System Units The system has detected that the units (temperature or distance) in the LPU/LSC are different from the Data Server units.

Remedy Different System Units Open the Process page of the Configure - System dialog and check that the units are correct and press OK. The LPU/LSC will be updated with the Server settings.

LPU_2E Started This message is for information only.

The system has initialised the connections (TCP/IP Ethernet) to the LPU/LSC processors.

No LPU_2E IP Addresses Configured. The IP address of the LPU/LSC has not been configured. No connection can be made to the LPU/LSC.

Remedy No LPU_2E Ip Addresses Configured Enter the IP address of the LPU_2E in the Equipment page of the Configure – System dialog.

Log Started / Log Stopped These massages are for information only.

Log Started indicates that the system event log has been opened ok.

Log Stopped indicates that the Landscan WCA software has shut down ok.

Wrong LPU_2E Version The software version of the LPU_2E processor is incompatible with this version of Landscan WCA.

Remedy Wrong LPU_2E Version The LPU_2E requires a flash update to the latest version. Please contact LAND Instruments International Ltd for instructions.


Did Not Receive Product Name via PDI The system is configured for product naming via PDI messages and a product was detected at the scanner, but no name was provided. A name will be generated from the alternative method configured in the Product page of the Configure – System dialog.

Remedy Did Not Receive Product Name via PDI This could indicate a fault in the connection to the external computer. Check that the computer is sending the PDI messages by looking at the diagnostics option on the Configure - Communications dialog.

System Configuration Created This message is for information only.

The system configuration has been re-set to the default factory values.

You will now need to re-configure the Landscan WCA software to your requirements.

Software Started With Products Under Scanners. This message is for information only.

The system has started and products have been detected under later scanners, Part Product names will be allocated to these incomplete products.

Product Tracking – Product Stuck The maximum product length timeout has timed out, indicating that a product that is larger than expected has become 'stuck' under the scanner.

Remedy Product Tracking – Product Stuck If there is a genuine production problem and the product has become stuck under the scanner, then this is for information only.

If the product is OK but longer than normal , then increase the maximum value in the Tracking page of Configure - System dialog to accommodate longer products..

If the product is continuous, the Landscan system needs to be configured to split the product up into discrete product files. Using the Product page of the Configure – System dialog set the product mode to 'Timed'.


Product Tracking – Product Un-Tracked The system's product tracking mechanism has failed to track the products through the system.

Remedy Product Tracking – Product Un-Tracked If there is a genuine production problem and the product has become stuck between scanners, then this is for information only.

The tracking mechanism can be reset from the Tracking page of the Configure – System Dialog.

If this event occurs frequently, then product information should be sent by TCP/IP PDI messages from the process computer.

Product Tracking – Extended gap between products The maximum gap between product's timeout has timed out, indicating that a product has not arrived at a later measurement station. The product may have become stuck between stations.

Remedy Product Tracking – Extended gap between products If there is a genuine production problem and the product has become stuck between scanners, then this is for information only.

If this is a normal travel time between scanners, then increase the maximum value in the Tracking page of the Configure - System dialog to accommodate longer gaps.

If the product is continuous, the Landscan system needs to be configured to split the product up into discrete product files. Using the Product page of the Configure – System dialog set the product mode to 'Timed'.

Could Not Access File, Possibly Deleted? The requested product file could not be located. The system may have deleted the file, as part of the oldest file delete file wrapping function.


Remedy Could Not Access File, Possibly Deleted? Check for the product in the Archive, it may have been moved there, if the move to archive function was active.

TCP/IP Error Reported by LPU_2E Processor A TCP/IP error has been reported by the LPU/LSC processor.

If the fault re-occurs, contact LAND Instruments International Inc. for details and assistance.

INI File Error Reported by LPU_2E Processor An error has been reported by the LPU/LSC processor, concerning the INI file message descriptor.

If the fault re-occurs, contact LAND Instruments International Inc. for details and assistance.

Incoming Message Error Reported By The LPU/LSC An error has been reported by the LPU/LSC processor, concerning the translation of an incoming message.

If external serial communications are in use to the LPU/LSC serial communications port, then this could indicate a syntax error in the incoming message. If there are no serial communications to the LPU/LSC and the fault re-occurs, contact LAND Instruments International Inc. for details and assistance.

No Scanner Signal The system cannot detect a scan valid signal from the scanner.

Remedy No Scanner Signal Check the integrity of the scanner and connections to the LPU/LSC as follows:

Confirm that the scanner has power and that the mirror can be seen to be rotating through the window.

Check that the scanner cable is connected to the scanner & the LPU/LSC.

Check the polarity of the scan valid signals at the LPU/LSC connector & reverse them if necessary (they are easier to change here).

Measure the signal at the LPU/LSC connector; if there is no voltage signal (0-5V pulse), check that the correct pair of wires has been selected.

If there are no signals at all in the cable, this indicates a break or short circuits in the cable.


Scanner Speed Too Fast This indicates that the measured scanner speed is faster than the highest speed for the scanner. This can occur is a 50Hz scanner is connected and the system is configured for a 25Hz scanner.

Remedy Scanner Speed Too Fast First check that the correct scanner type is selected.

LS Head

If the scanner speed is controlled by remote control, check that the signal is functional. The fault could indicate that the 4-20mA signal is either not connected or operating at greater than 20mA.

If the speed setting is set in the head, check that the speed plug is NOT set in the slow LASER speed setting.

LSP Head

Check that the scanner laser button is not activated or that the remote laser trigger is not active.

Check the actual scanner speed as reported to the Landscan WCA software.

See:


Scanner Speed Too Slow This indicates that the measured scanner speed is slower than the lowest speed for the scanner.

Remedy Scanner Speed Too Slow First check that the correct scanner type is selected.

LS Head

If the scanner speed is controlled by remote control, check that the signal is functional. The fault could indicate that the 4-20mA signal is either not connected or operating at greater than 4mA.

If the speed setting is set in the head, check that the speed plug is NOT set in the slow LASER speed setting.

LSP Head


Check that the scanner laser button is not activated or that the remote laser trigger is not active.

Check the actual scanner speed as reported to the Landscan WCA software.

See:


Stabilizing This indicates that the scanner speed has changed and the system is attempting to synchronise with the new scanner speed.

This is reported when the scanner type is changed, the scanner speed is changed or the power has been disconnected and re-connected to the scanner.

The error should clear after a few minutes and therefore no action is required.

If the fault persists, this could indicate:

An intermittent cable fault with the scan valid signal.

A faulty remote control scanner speed signal (If installed).

Noise on the scan valid signal.

TCP/IP_ERROR_10054 The associated event message can take different forms, these include (for example):

TCPIP receive error

Send fail to : 10.1.10.120 Command=SLD

In all instances the event indicates a communications error has occurred on the TCP/IP connection to the LPU/LSC.

This is normally associated with the powering off of an LPU/LSC or the disconnecting of the network cabling/equipment between LPU/LSC and Data Server computer.

The status bar will show the following:


LPU/LSC Connection Errors The Landscan WCA software was unable to establish a connection to the LPU/LSC across the network.

Remedy LPU_2E Connection Errors Check the network connections and settings:

Check power is correctly applied to the LPU/LSC unit.

First check that there is a valid connection between the Data Server and the LPU/LSC, if there is a hub or switch between the LPU/LSC and the Data Server; check that the 'connected ' LED's indicate a good connections. If there is no indication for the LPU/LSC link, power reset the LPU/LSC. (The LPU/LSC auto detects the media type on power up, and hence must be powered up last.)

Check that the IP Address of the LPU/LSC is the same as the IP Address configured in the Equipment page of the Configure – System dialog. And that the Port Number of both is set to 1050. To check the IP Address and Port Number of the LPU/LSC Processor it is necessary to use the Landscan Processor Configuration software.

The integrity of the Ethernet settings can be tested by using the 'Ping' facility of Windows. Instructions for using the Ping Command can be found in Network Installation.

Copy Of File To Archive Has Failed The Landscan WCA software is unable to create an archive file of the required product.

Close any display on the Landscan WCA software showing stored product data files.

Stop the Landscan WCA software.


Reboot the Data Server.

Restart the Landscan WCA software.

Retry the archive function.


Could Not Update The Archive Catalogue The Landscan WCA software is attempting to create an archive product data file. In doing so the file has been created but the Landscan WCA software has been unable to update the list of archived files.



Go to the directory that contains the archive files, by default \LandscanArchive. Delete any file titled ProductInfo, regardless of the file extension. Empty the Windows Recycle Bin of the Data Server.





No Disk Space For Archiving See:

No Disk Space to Archive Products

Could Not Access The Storage Catalog The Landscan WCA software is attempting to create an archive product file. In doing this the Landscan software attempts to locate the original data currently stored in the database BUT this has failed.








LPU/LSC Has Power Reset This message is for information only.

This is logged following a power up of the LPU/LSC.

This is a historical event; the system is now operating ok. For further information, the Diagnostics – LPU/LSC dialog lists the data and time of this power reset.

No Fast Temperature Signal This indicates that the system has failed to detect a 4-20mA Fast temperature signal from the scanner after the scan valid signal has tested ok.

The Landscan WCA software will be unable to display any data detected by the scanner until this problem is addressed.

This check is made on LPU/LSC power up, scanner power up and when the scanner type is changed.

If a window displaying the temperature profile of the connected scanner has a red border then the scan valid signal is also disconnected. If not then the scan valid is connected correctly but the fast temperature signal isn't.

In this scenario a temperature profile would be a perfectly flat line at the lowest temperature the scanner can read. If this is the case then it is necessary to check the polarity and connectivity of the fast temperature signal.


With the scan valid and fast temperature connected correctly and no product currently under the scanner the profile will be a flat line but experience has shown that this always contains a small amount of "noise" which can be attributed to the ambient environment.

Remedy No Fast Temperature Signal Check the fast temperature cable connections to the scanner, the signal is either not connected or the signal polarity is incorrect.

Check the polarity of the signals at the LPU/LSC connector and reverse them if necessary (they are easier to change here).

Documentation of the correct wiring of the Fast Temperature Signal can be found in the Processor Installation Guide.

LPU/LSC Processor Internal Error An event has been reported by the LPU/LSC processor, concerning its internal operation.

If the event re-occurs, contact LAND Instruments International Inc. for assistance.

Clear the current alarms to help show when the next event occurs.


Or

TCP/IP Error 10060 and 10061 In all instances the event indicates a communication error has occurred on the TCP/IP connection to the LPU/LSC.

This is normally associated with the powering off of an LPU/LSC or the disconnecting of the network cabling/equipment between LPU/LSC and Data Server computer.

The status bar will show the following:


System Configuration Update Errors The Landscan WCA software uses a database to hold the software configuration. This is a fundamental part of the Landscan WCA software and if events/errors occur then this may make the Landscan WCA software unstable.

If these events happen repeatedly then contact LAND Instruments International Inc. for assistance.

Scanner Signal OK An event of this type will be generated for each LPU/LSC when it has the scanner signals correctly connected to it and the LPU/LSC is acquiring data from the Scanner. Both the scan valid signal and the fast temperature signal must be correctly connected for this event to be generated.

The number in the data stream column (of the event viewer) indicates which LPU/LSC generated the message. The first LPU/LSC connected to the system is always stream number 1. This number increments for each connected LPU/LSC.

TCP/IP Error 11004 Windows NT Only

This is generated when the TCP/IP services file is corrupt, or contains incorrect data, which means that the Data Server computer cannot connect to any LPU_2E units.

The services file by default resides in directory

\WINNT\SYSTEM32\DRIVERS\ETC.

In order establish communications to an LPU_2E unit this file must contain the entry :

lpu2 1050/tcp


Remedy TCP/IP Error 11004 Stop the Landscan WCA software.

Use Windows Explorer to navigate to

\WINNT\SYSTEM32\DRIVERS\ETC

Open the services file (use the Notepad editor).

Ensure that the file contains an entry

lpu2 1050/tcp

if not then add the entry, save the file and retry communications to the LPU_2E units.

If the entry is preceded by a '#' character then it is "commented out". The '#' should be removed, save the file and retry communications to the LPU_2E units.

If no services file exists then this is because the TCP/IP protocol is not installed on the computer. It will be necessary to install this before continuing.
