3. Introduction

3.1. The concept

The ECC-DFC fieldbus controller that is used for conveyor belt control is a series of individual ECC-DFC modules that are connected to each other via Ethernet cabling in order to provide a complete solution for the function of motor rollers in conveyor systems. Each module can operate up to 2 ECR motor rollers and 2 photo sensors in order to control up to 2 conveyor belt zones.

Each ECC-DFC module also has practical interfaces to the upstream and down-stream Ethernet network cabling.

Figure 1 ECC-DFC fieldbus controller with 3 MODULES

The software of ECC-DFC modules can be easily configured in order to operate several zones of linear conveyors with the ECShell engineering software. The default settings of each ECC-DFC module can also be modified using ECShell in order to adapt the function to specific applications.

Automatic logic for detecting and processing load sizes that exceed the length of a

physical zone

Optional configuration for “Look Ahead Slow Down” mode for applications with faster

speeds

Capability of bridging separate Ethernet network sections for smooth operation

Possibility of using an ECC-DFC as an extension of another ECC-DFC so that it acts

as a simple motor controller

Introduction

3.4. Overview of the hardware

ECC-DFC modules are designed such that they can be installed and integrated in the side frame of the conveyor belt.

ECC-DFC modules can be used to control up to 2 motor roller zones of the con-veyor belt. Each ECC-DFC has interfaces for 2 motor roller zones with the asso-ciated 2 photo sensors and an upstream and downstream network. There are also discrete connecting locations for setting up a complete control system for the motor roller conveyor systems, which are divided up into zones.

20


4.3. Left and right Ethernet connections

Both connections are RJ45 sockets that correspond to the pin assignment of the Ethernet connection. In order to comply with degree of protection IP54, Ethernet cables must be equipped with protective sleeves.

Figure 6 shows the used Ethernet cables with sleeves to protect the RJ45 con-nector at the Ethernet cables. The scope of delivery of each module includes 2 sleeves.

21

In order to correctly fit the IP54 protective sleeve to the RJ45 connector, a special tool is required. Figure 9 shows a Phoenix Contact 2891547 FL IP 54 assembly tool.

INFORMATION

This tool is not included in the scope of delivery!

Figure 9 shows a Phoenix Contact Ethernet switch 2891547 FL IP 54 assembly tool

NOTICE!

It is advisable for all Ethernet cables between the modules to be shielded. The use of unshielded cables can lead to loss of data and unexpected results.


22


4.4. Power connections

4.4.1. IP54 installation

Parts [12] and [17] as shown in figure 2 are not connected to the module when it is delivered but are supplied separately in the module box. These parts are needed in order to create a power wiring installation that is compliant with IP54.

The power cables are routed through the cable gland [17]. The cable terminals are standard spring terminals.

When the wiring is complete, the power wiring compartment is securely closed off with a cover [12].



23

4.4.2. Logic and motor roller current supply

Each module of the fieldbus controller has separate power connections for the module logic and the motor, so that these can be supplied via separate current supply units.

For example, the motor current supply can be switched off using an emergency stop system, so that all motors are de-energized. If the motor current supply op-erates separately, the logic current supply can remain switched on so that the module communication is still active and can transmit status messages to moni-toring systems.

Figure 11 shows a wiring diagram for separate logic and motor roller current supplies, and the wiring diagram in figure 10 shows the single current supply of the logic and the motor rollers.

Note that the supply to the motor roller terminal simultaneously also supplies the logic with power.

Figure 10 Connection of a single current supply for motor rollers and logic

Figure 11 Typical connection of separate current supplies for motor rollers and logic


24


4.4.3. Grounding of the current supply

Regardless of whether the logic and the motor rollers have a shared or a sepa-rate current supply, the DC supply ground connections (“-”) must be connected. One of the two current supplies must have a grounded DC connection. Direct ground connection of more than one current supply DC connection must be avoided, since this can lead to unintentional ground loops. Figures 12 and 13 show a single and a separate current supply and their DC supply ground and grounding connections.

Figure 12 Single current supply with combined DC supply ground and grounding connections

Figure 13 Double current supply with combined DC supply ground and grounding connections

NOTICE!

This document assumes that the user knows the power requirements of the mo-tor rollers for the relevant application and that the DC 24 V current supplies and the wiring are correctly dimensioned on the basis of the applicable directives and standards. It is also assumed that the devices are correctly grounded during in-stallation. The DC current supply ground or “-” must always be grounded at all current supply units. Incorrect dimensioning of the current supply and/or incor-rect grounding can have unexpected results.

Connections for linear conveyors


25

5. Connections for linear conveyors

The fieldbus controller is designed for linear conveyor operation in such a way that an auto configuration process runs, which is carried out by the ECShell engi-neering software.

Before the auto configuration process can be carried out, each individual module of the fieldbus controller must be correctly connected to the assigned motor roll-ers and photo sensors in order to achieve the required operating results.

In general, each module detects the sensor connection to which a device is con-nected and determines its specific configuration as soon as the auto configura-tion process has triggered auto configuration.

Before the system is configured for operation, each motor roller and each photo sensor must be correctly connected to the modules fitted to the conveyor belt. The fieldbus control modules then determine the operating mode on the basis of the way in which the photo sensors and motor rollers are connected.

An individual ECC-DFC module can be operated as:

a 2-zone controller with 2 motor rollers and 2 photo sensors

a 1-zone controller with 1 motor roller and 1 photo sensor

a 1-zone controller with 2 motor rollers and 1 photo sensor

These connection types are shown in the following examples.

5.1. Example 1 – Two-zone controller

In this example, a motor roller and a photo sensor are connected to both the left and right interface area. The module will control the 2 motor rollers as independ-ent logical conveyor belt zones.


26


5.2. Example 2 – Single-zone controller

In this example, a single motor roller and a single photo sensor are connected to either the left or right interface area. The module controls the motor roller as an individual, independent logical conveyor belt zone.

5.3. Example 3 – Double-motor-roller, single-zone control

In this case, the module will control 2 motor rollers together and operate them as a single zone with a single photo sensor, which is connected to either the left or right connector. This configuration is typical especially for inclined conveyor belt zones, since inclined conveyors need the additional torque of a second motor roller to transport loads.

5.4. Examples of invalid configuration

Since the auto configuration of the ECC-DFC is determined by how the photo sensors are connected, it is possible to connect photo sensors and motor rollers in the wrong way, which can lead to unexpected results.

In these cases, the module will attempt to operate as a single-zone controller, but the motor rollers are not connected to the same left/right interface area as the photo sensors.



27

The module will now attempt to act as a two-zone controller, even though only one motor roller is connected.

INFORMATION

These invalid configurations will not lead to the auto configuration function being aborted. The user will notice only the occurrence of faulty operation and/or unex-pected results.

5.5. Definition of motor direction of rotation

The fieldbus control modules use two definitions of the motor direction of rotation:

clockwise (CW)

counter-clockwise (CCW)

The definition of the motor direction of rotation is based on the view of the motor roller from the cable output side of the roller, as shown in figure 14.

Figure 14 motor direction of rotation

Status displays

28


6. Status displays

The module status is indicated using several LEDs. With the exception of the Ethernet link and activity LEDs, all LEDs are multi-colored and context-sensitive. The different meanings of all LEDs are explained in the following table. The num-bers relate to the positions on the module; see figure 2.

An ON/OFF cycle lasting for about ½ a second is regarded as “slow flashing”, whereas an ON/OFF cycle lasting for about ¼ of a second is regarded as “fast flashing”.

Auto configuration of the linear conveyor

7. Auto configuration of the linear conveyor

The goal of auto configuration of ECC-DFC networked fieldbus controllers is to provide a simple and fast way of starting up a linear conveyor system. The func-tion of the ECC-DFC fieldbus controller for auto configuration requires the use of the ECShell engineering software on a PC that is connected to the network mod-ule that is the furthest upstream.

7.1. Definition of a linear conveyor

Auto configuration can be used in only a linear conveyor system. A linear con-veyor system is defined as a single uninterrupted conveyor line without mixing or diversion mechanisms. A linear conveyor can contain curve sections, but the flow of the transported material takes place continuously from the infeed zone to the unloading area.

Figure 15 Simple example of a linear conveyor

A networked ECC-DFC solution is capable of controlling complex conveyor lines that also contain diversion or mixing equipment. However, configuration with a PC and software is required for this. Information about PC-based configuration can be found in the self-help dialog of the ECShell engineering software.

7.2. Installation of the ECShell engineering software

The files for ECShell are normally transmitted or downloaded in compressed for-mat. As soon as you have extracted the contents of the compressed file, you are provided with a folder with a name in the following format:“ECShell_Vx_nn”. “x” represents the number of the main version, and “nn” is the revision number. There is a file called “Setup.exe” in this folder.

Double-click this file to start the installation procedure. ECShell will be installed like any standard Windows application, and you will receive the typical Windows entry requests.

If you accept the default specifications, ECShell installs itself on the local operat-ing system drive under "\Program Files (x86)\Industrial Software\ECShell\" or "\Program Files\Industrial Software\ECShell\".



31

7.3. Definition of the ECC-DFC Ethernet

INFORMATION

Important basic information about understanding IP addresses in the Ethernet network and subnetwork terms can be found in “Appendix B – Configuring the PC for Ethernet subnetworks”. The description in this section assumes that you have general knowledge of IP addresses and subnetworks.

All fieldbus control modules communicate via the Ethernet network and use TCP/IP-based protocols for normal operation. In order to work correctly, all TCP/IP protocols assume that a unique IP address is assigned to every device in the network.

An IP address has the following format: AAA.BBB.CCC.DDD, whereby AAA, BBB, CCC, and DDD are numeric values between 0 and 255.

In the case of ECC-DFC, the AAA.BBB.CCC part of the IP address is defined as the subnetwork (subnet). The DDD value is referred to as the node.

If, for example, a fieldbus controller module has the IP address “192.168.25.20”, its subnetwork address is “192.168.25” and its node is “20”.

A temporary IP address is allocated to each ECC-DFC in the factory, which is used by the automatic testing equipment so that each fieldbus controller module can be tested prior to shipping. When a module is removed from its packaging, this IP address is still stored in it.

When the auto configuration procedure starts, a new IP address is automatically assigned to each module. For all modules, this IP address is determined by the subnetwork of the IP address that is already stored in the module that is chosen as the auto configuration master.

Regardless of whether all modules downstream of the auto configuration master have the same or different subnetwork or node values, their subnetwork is changed to that of the auto configuration master.

Furthermore, during the auto configuration procedure, the node value of the con-figuration master is changed to 20. All downstream modules of the fieldbus con-troller are then automatically given a node value starting with 21.


32


Figure 16 shows 4 modules as they have been installed on the conveyor belt immediately after unpacking. As soon as the auto configuration master deter-mines and the auto configuration procedure has been carried out, the IP ad-dresses of all 4 modules are configured as shown in figure 17.

Figure 16 IP addresses before auto configuration

Figure 17 IP addresses after auto configuration

The auto configuration procedure assigns nodes up to and including 240. Each subnetwork is therefore limited to 220 nodes.



33

7.4. Connect PC to the fieldbus controller network

Connect the Ethernet connection of your PC to the auto configuration master using an Ethernet cable as shown in figure 18.

Figure 18 Initial connection of a PC to the ECC-DFC subnetwork

NOTICE!

The PC must be connected directly to the network of the fieldbus controller. Avoid connecting via Ethernet switches or wireless routers/switches. If a wireless switch is not correctly configured, the recording function will not work. You should also ensure that the firewall of the network is disabled.

7.5. Auto configuration procedure

The flow direction of the conveyor system determines how the auto configuration procedure is started. The module that is the furthest upstream or the closest to the infeed end of the conveyor belt is defined as the auto configuration master. The auto configuration procedure is initiated by the auto configuration master. Because of its physical location on the conveyor belt and in the Ethernet connec-tion chain, the auto configuration master automatically connects to all down-stream modules and configures their IP addresses for communication. The pro-gram then automatically configures the flow direction.

The following processes have to be observed:

1. Start the ECShell engineering software and press F2. Choose “Network Services” in the dialog window and click “Discover”.

2. When the modules of the fieldbus controller appear in the module table, choose the one that you want to configure and click “AutoConfig”, as shown in figure 19.

3. When the topology has been set up, select the module from which you wish to configure the line and click “AutoConfig From the Selected Node”, as shown in figure 20.

4. This triggers the auto configuration process, which will propagate itself on all following fieldbus controller modules and configure the entire line.


34


NOTICE!

In order for the auto configuration process to work properly, the transported ma-terial must be removed from the entire conveyor line, and all photo sensors must be set so that none of them detect a load in their respective zone. Failure to comply with these conditions will lead to unexpected results.

INFORMATION

Note that the number of modules per subnetwork is limited to 220.

Figure 19 “Discover” process



35

Figure 20 Topology view and initiation of auto configuration from selected nodes

Note that in the topology view, the detailed information for each module is shown in RED if the module has not been configured. You can also select the module graphic from the topology view, right-click to display the context menu and initiate the auto configuration from there, as shown in figure 21.

Figure 21 Auto configuration by selecting the node in the “tree” view


36


The node selected for auto configuration does not have to be the first module that is directly connected to the PC. The module at the other end of the line can also be selected as the auto configuration master, as shown in figure 22.

Figure 22 Auto configuration from the node furthest away from the PC

7.5.1. Automatic detection of the position of the module at the opposite side

The cable connections between the left and right Ethernet connection can be used if the module is going to be installed at the opposite side frame of the con-veyor system. When it is correctly connected, it is detected by the auto configura-tion program, and the flow rate is configured accordingly.

Figure 23 shows an example of the detection of the opposite position.

Figure 23 Example of a module positioned at the opposite side



37

7.6. Results of auto configuration

7.6.1. Normal results

When the auto configuration procedure is complete, each module of the fieldbus controller is automatically restarted. If a module has been successfully configured and has been restarted, its module status LED flashes in green.

INFORMATION

Note that the duration of the auto configuration depends on the number of mod-ules to be configured. It takes longer to configure bigger networks than smaller networks.

The topology view shows the detailed information of the module in black text (no longer red) when the auto configuration has been successfully completed; see figure 24.

Figure 24 Auto configuration successful

If all module status LEDs flash in green, a load is placed in the zone that is fur-thest upstream in order for complete verification of the configuration: If the auto configuration was successful, the load is transported to the discharge zone. If this does not occur, you can look up possible errors and the remedying thereof in chapter “Problem solution for failed auto configuration”.


38


INFORMATION

Note that another auto configuration request of some module or other in the fieldbus controller that is not the auto configuration master will not start another auto configuration procedure. The module concerned will detect that it is not the unit that is the furthest upstream and abort the procedure. Nevertheless, the module will carry out a local restart. This process lasts a few seconds.

7.6.2. Problem solution for failed auto configuration

The following table contains some typical indicators of error statuses and the rel-evant measures to be taken as the solution.

Error status Measure

Status LEDs OK with unexpected result

Check the function of all photo sensors and whether all zones are free and repeat the procedure.

Check all networks, motor rollers, sensors, and power connections and repeat the procedure.

Make sure that all connections are valid. Correct invalid connections and repeat the procedure.

The status LED is flashing or illuminated in red at one of more modules

Ensure that no Ethernet switches or PCs are connected between the modules of the fieldbus controller. The auto configuration procedure is aborted if a device that is not part of the ECC-DFC is detected along the path to the final node. Modules up to this point are configured, but the others are not.

If a module is removed from an existing network that is already operational, wait for at least 2 minutes so that the Ethernet switches at the remaining modules can reset before a new auto configuration procedure is started.



39

7.6.3. Single release mode/singulation (ZPA)

Loads are normally transported from upstream to downstream zones in single release mode. A load that reaches the photo sensor of the final zone causes the motor in the final zone to continue running in order to transfer the load to the next conveyor or the next position.

In single release mode, each zone waits until the next is free before it starts up. This mode ensures that at least one zone length is free between the transported loads. If the first load has to be stopped and the following loads accumulate, these are stopped in their respective zones as soon as their front edge reaches the photo sensor of the zone. Figure 25 shows a typical example of the single release.

Figure 25 Example of single release mode


40


7.6.4. “Flex Zone” detection function

The fieldbus controller detects automatically if a box is longer than a zone length and automatically adapts the accumulation control so that the longer box then occupies two logical zones. This prevents the next upstream box from being transported into the longer box. “Flex Zone” mode operates in both singulation mode and train release mode.

Figure 26 Example of “Flex Zone” mode

NOTICE!

Note that “Flex Zone” mode works with only box lengths of up to 2 zone lengths.

The operation of a conveyor system with boxes whose length exceeds 2 zone lengths leads to an excessive number of jam statuses and errors.

INFORMATION

Definitions and applications of other available ZPA modes can be found in the help function of the ECShell engineering software.



41

7.7. Jam statuses

The ECC-DFC detects two types of jam status:

Sensor jam

“No Arrival Jam”

7.7.1. Sensor jam

If a load is still blocking the photo sensor in an upstream zone after an attempt has been made to transport the load to the next downstream zone, the controller detects a sensor jam. This is indicated as shown in the table in the section enti-tled “Sensors”. If the load has been removed from the vicinity of the photo sensor, the sensor jam is automatically canceled if the standard 5 seconds of the reset timer have elapsed.

After a sensor jam has occurred or if the sensor remains blocked, the controller will attempt to remedy the situation. First the controller will allow the motor of the affected zone to run slowly backwards for 1 second in order to clear the blocked sensor. If the sensor is still blocked after this first attempt, the controller will re-peat this movement twice. If the sensor is clear after one of these three attempts, the zone returns to normal function, and the controller will attempt to continue transporting the load under normal ZPA control.

If the sensor is still blocked after three attempts of this motor reversal cycle, the zone remains in sensor jam status, and the load must be removed manually in order to restart the zone.

7.7.2. “No Arrival Jam”

If a load leaves an upstream zone and is transported to the next downstream zone, the upstream zone expects a confirmation of receipt from the downstream zone. This communication takes place automatically within the network of the fieldbus controller.

If a new load arrives in the upstream zone while this is still waiting for a confirma-tion of receipt from the downstream zone, the new load will jam in this upstream zone. If the upstream zone does not receive the confirmation within the jam timer time interval, the controller will generate a “No Arrival Jam” error message.

As soon as a “No Arrival Jam” occurs, the controller automatically stops all new loads in the upstream zone for a preset time and then continues with the normal ZPA function. By default, the time settings of the jam timer and the reset time are the same, i.e., the maximum time for which a new load would jam in the upstream zone would be 5 s + 5 s = 10 s.

INFORMATION

The 5 second jam timer time is a preset value. Instructions for modifying this val-ue can be found in the help function of the ECShell engineering software.


42


7.8. Network error

In cases where the Ethernet network connection between the modules of the fieldbus controller is interrupted during operation, loads continue to be transport-ed and jam in the downstream zone that is furthest from the location where the network has been interrupted. This furthest downstream zone will automatically jam the load and not allow any further transportation in the downstream flow di-rection. As soon as network communication is restored, the zone returns to nor-mal operation.

7.9. Low voltage fault

In cases in which the controller detects that its supply voltage has dropped below DC 18 V, it will put its configured zone(s) into jam mode. The controller will retain this condition until it has determined that its input voltage has increased to at least DC 21 V.

NOTICE!

Repeated temporary stopping or delaying of normal zone-to-zone movement may be an indication of low voltage.

If this behavior is observed continuously, measure the voltage at the point that is furthest from the current supply unit and check the dimensions of the current supply and the wiring techniques in order to ensure that the correct voltage is provided at all modules.

INFORMATION

The ECShell engineering software has several diagnosis functions. These can be used to determine how often the current supply has dropped below DC 18 V. This can assist with finding electrical problems in the system.

7.10. Automatic module replacement

If a linear conveyor with auto configuration has been started up, the modules of the fieldbus controller store the configuration data of their neighboring modules. This configuration data is updated automatically, even if the parameters of the linear conveyor are modified by the ECShell engineering software. The firmware of the ECC-DFC uses this function for easy module replacement, so that the en-tire linear conveyor system does not have to be reconfigured if a single module is replaced.

INFORMATION

Automatic module replacement is used to replace modules in systems with sev-eral subnetworks. It is not necessary to temporarily interrupt network connections or isolate the subnetwork in which the replacement is going to take place.



43

7.11. Module replacement

Proceed as follows to replace a fieldbus controller module:

1. Disconnect all module connections: Motor(s), network, photo sensor(s), hardware, and power. The order does not matter.

2. Connect the new module to the motor(s), sensor(s), hardware, network, and power.

3. Start the ECShell engineering software.

4. Press F2 and click Discover in the Network Services tab.

All modules in the network are now displayed.

5. Click the "AutoConfig” button as shown in figure 27.

The topology of the modules is displayed within a few seconds.

6. Select the module to be replaced from the list on the left-hand side and click “Replace Selected Node” as shown in figure 28.

Note that the text information for this module is displayed in RED in the topology

view.

Wait until the module has completed its internal boot-up procedures, which is indicated by a module status LED flashing in green.

8. ECShell engineering software

8.1. Introduction

The ECShell engineering software is a PC-based application for configuring an ECC-DFC-controlled conveyor system. ECShell also makes it possible to modify preset module parameters.

INFORMATION

The previous sections describe how to install ECShell and perform the initial auto configuration.

8.1.1. Basic functions

Some of the basic parameters of the modules that can be configured using EC-Shell are:

ZPA mode selection (“Singulation”, “Train” etc.)

Type of motor roller (ECO or BOOST)

Direction of rotation of the motor roller

Motor roller speed, acceleration values and braking values

Time settings for jam statuses and “Run After” function

Settings for “Look Ahead” deceleration function and “Lane Full” interface

“Blink&Wink” function for visual locating of a module in the conveyor system

ECShell makes it possible to modify these parameters for an individual module or a group of modules simultaneously.

ECShell can display the status information for each module in the subnetwork of the network.

8.1.2. Extended functions

Some of the extended functions that are available with ECShell are listed in the following:

Firmware updating for an individual module or a group of modules.

“Discover” function for finding all modules in a network and manually setting their IP

addresses.

Mapping for module connection, for logically linking two or more separate ECC-DFC

networks.

Extensions which make it possible for a module to switch off its ZPA function in order

to be logically linked with the motor controller of a neighboring module.

Selecting the PLC allows a module to switch off its ZPA function in order to be logical-

ly controlled by an external PLC.

The capability of backing up and restoring the network configuration.

The possibility of restoring a backup according to IP or node. Restoring according to

IPs is useful if part of the system or the entire system is to be duplicated.


46


8.2. Options for configuring the IP address of a PC

INFORMATION

Note that the IP address of the PC does not have to belong to the same subnet-work as the fieldbus controller modules to perform the auto configuration with the ECShell engineering software. The IP address of the PC must be set correctly in order to read and modify the parameters correctly.

If a fieldbus controller network or subnetwork has been configured using auto configuration, one of the three following procedures must be used to enable the PC to connect to the subnetwork and use the ECShell engineering software:

Option Description

Method 1 Allow the DHCP service that is integrated in the fieldbus controller to automatically assign an IP address to the PC.

Method 2 Manually change the IP address and/or the subnet mask of the PC to adapt it to the subnetwork of the fieldbus controller.

Method 3 Manually change the IP address of the auto configuration master to a new subnetwork that is accessible to the IP address that is already configured in the PC.

All of these options are valid. The one that is used is entirely up to the user.

8.2.1. Method 1 – using the DHCP service for assigning an IP address

If you connect to a single subnetwork of a system and if the PC is configured in such a way that it is assigned its IP address, it is advisable to allow the network to automatically assign an IP address to the PC using the integrated DHCP ser-vice. This is the simplest method, particularly if the PC is already set to having its IP address assigned.

If you use the DHCP service of the fieldbus controller to assign the IP address, you do not need to start ECShell to do this. If you follow the procedure described in section “Changing the IP address of the PC” in Appendix B – “Configuring the PC for Ethernet subnetworks”, you will see the TCP/IP characteristics of the PC.



47

If the PC is configured so that it auto-matically receives an IP address, all you need to do is connect the PC as shown in figure 18. The IP address of the PC is configured so that the EC-Shell engineering software can be used.

Manual methods for configuring the IP addresses

With bigger system configurations with several subnetworks and/or systems to which a certain PC is to be connected without interruption, manual configuration of the IP address of the PC is preferable.

If several subnetworks of the fieldbus controller share the same physical Ethernet cabling (directly or via Ethernet switches), it is advisable for the subnetworks to be defined and for each auto configuration master to have its subnetwork as-signed before carrying out the auto configuration procedures.

Since all of the subnetworks that are required have already been defined, the PC can set its IP address and subnet mask accordingly so that you can access all subnetworks of the fieldbus controller from a single PC with the ECShell engi-neering software.

Regardless of which manual procedure you have chosen, you can always com-plete it with the PC and ECShell.

Use of ECShell for localizing the auto configuration master

Every manual method for configuring the IP address requires access to the IP address of the auto configuration master with the aid of the ECShell engineering software.


48


Starting ECShell

If you have carried out the standard installation of ECShell, the program can be selected using “Start\All Programs\Industrial Software\ECShell”. If you chose a different storage location during the installation, start “ECShell.exe” from there.

When you start ECShell for the first time, a window like the following one is dis-played, with deactivated status values and empty parameter check boxes.

Regardless of whether you have to change the IP address of the PC in order to adapt it to the subnetwork that has already been configured, or whether you change the auto configuration master of the subnetwork in order to adapt it to a subnetwork address, a connection with the auto configuration master must al-ways be established.

Use of the network help program

The “Discover” function allows the PC to search for any modules of the fieldbus controller that are physically connected to the network, independently of the IP address settings of the PC or the modules.



49

Proceed as follows to use the “Discover” function:

1. Press F2 in order to call up the “Advanced Dialog” function.


50


2. Click the “Network Services” tab.

If you have selected the “Network Services” tab, a window appears in which you

not only see the connected modules but can also select modules whose IP

address setting you would like to modify.



51

3. Click “Discover” in this window.

After you have clicked “Discover”, ECShell queries the network and displays a list of all modules that it finds, including the IP address, the serial number, and the current firmware of each module.

The auto configuration master is the module with node 20.

In this example, 3 modules were found. The auto configuration master has IP address 10.10.10.20, its serial number is 268229, and it uses firmware version 4.13.

INFORMATION

You can find more information about the other tabs in the “Advanced Dialog” window in the “Advanced Dialog” section.


52


8.2.2. Method 2 – Modifying the PC to adapt to the auto configuration master

Since you now know the IP address of the auto configuration master, you can simply change the IP address configuration of the PC at this point so that it has access to the subnetwork of the auto configuration master. In the example shown above, the IP address of the auto configuration master is 10.10.10.20, according to which the subnetwork is 10.10.10.

8.2.3. Method 3 – Modifying the IP address of the auto configuration master

If you would like to modify the preset IP address of the auto configuration master that was used when the auto configuration procedure was carried out, you can do this in the network service window.

Double-click the auto configuration master in the list. This results in its IP address information being filled in, as shown in the following figure. Now enter the new IP address information that you would like to use and click “Set”.

If you click “Discover” again after clicking “Set”, ECShell updates the module list on the left-hand side. You can now check whether the new settings of the IP ad-dress have been copied for the module.



53

INFORMATION

The subnetwork concerned will no longer work from this point in time, since the IP address of its auto configuration master has been changed. You must now perform the auto configuration procedure again so that the IP addresses of all downstream modules are updated in order to match the address of the auto con-figuration master subnetwork.

8.3. ECShell main window

Once you have changed the configuration of the PC or that of the auto configura-tion master as described, you are able to use the ECShell main window. You can have the status of the system displayed and modify parameters here. If you pro-ceed as shown in the example above, the main window is displayed when you close the advanced dialog.

The main window is also displayed when you start ECShell for the first time.

Figure 30 ECShell main window

[1] Network IP – This is where you enter the subnetwork of the network to


54


which you would like to connect

[2] Node No. This is where you enter a range of nodes in which a connection is to be established. If entries are made in these fields, an update automatical-ly takes place. If you click “Refresh”, all of the other fields (3, 4 and 5) are also updated.

[3] Upstream Zone/Downstream Zone – This selection allows you to change the ZPA mode of a certain zone and let the zone to run using diagnosis control-lers (“Forced Run”) and give the zone the command to jam when a load ar-rives.

[4] Left Zone/Right Zone Settings – The motor roller type, braking method, closed loop control, speed, direction, as well as the acceleration and braking values can be selected. The values of one or more modules can be set us-ing the “Set” and “Set All” buttons.

[5] Force Run – On/Off changeover switch for operating the motor of the local zone

[6] Force Accumulate – On/Off changeover switch for putting the local zone into accumulation mode

[7] Configuration Indicator – A graphical display of the current module configu-ration is shown in this area

INFORMATION

Note that some information in your system may differ from the details described here, and that the majority of fields are empty until communication is started.

8.4. Establishing a connection with the ECC-DFC fieldbus controller

As soon as the correct subnetwork has been entered in the network IP fields [1], you can enter a series of nodes [2] that you would like to connect. The “Refresh” button is activated.

Click “Refresh” and the data fields of the other main window will be initialized.

8.4.1. Node navigation

From Node #

The node that is entered in the first field is the module whose data is displayed in the other main window.

To Node # The node that is entered in the second field does not have to be the “final” node of the network. If a value is entered that is larger than the number of existing nodes, an error message is displayed after you click “Refresh”.



55

In the example that is shown, only 10 nodes have been installed, but "12" was entered. After “Refresh” is clicked, two error messages are displayed one after the other.

[-][+] The node value in the first field can be increased or decreased by clicking “+” and “-”. The data for the newly selected node is then displayed. Note that increasing the value beyond the final physical node will generate an error message.

8.4.2. Node identification

The main window of ECShell contains a function that is known as “Blink&Wink”. This window allows you to visually verify the selected node.

If a valid node has been entered in the first field under “Node No.” and its data is display in the main window, clicking “Blink&Wink” will make all LED indicators of the selected module blink. Clicking “Blink&Wink” again switches the blink-ing off.

8.4.3. Module diagnosis window

Click the ECC-DFC icon in the top right-hand corner of the main window to open the “Diagnosis” window and display the current status of the selected node.


56


The current status of the selected connected module is displayed in the “Diagno-sis” window that opens. The window displays both the current status of the mod-ule and the zone status of the upstream and downstream connections of this module. The statuses of the connected sensors and motors are also displayed. An example is shown in figure 31. The descriptions of the different displays fol-low.



57

Figure 31 Example of a module diagnosis window

[1] Sensor status – OFF means sensor is clear; ON means sensor is blocked

[2] Status of local upstream/downstream zone

[3] Status of zone upstream of module – “-“ means that no connection is config-ured

[4] Status of zone downstream of module

[5] Current status of connected motor – the current strength, motor type, and direction of rotation are displayed. Note that a red “!” means that no motor current is present at the module

[6] No motor connection – in this example the module is configured so that it has 2 zones and 2 motors, but the connection to the motor of the down-stream zone has been interrupted, which is indicated by a red “X”


58


An extremely useful function of the module diagnosis is the possibility of having the relevant parameters and the part number and serial number of the connected rollers displayed in a dialog window. As soon as the mouse is moved over the picture of the respective roller, the information is displayed; see figure 32.

Figure 32 Module diagnosis displays motor roller data

8.4.4. Configuration of the upstream/downstream zone

If you have selected the node that you would like to examine and/or modify, you can select the settings.

The drop-down menu for “ZPA Mode” shows all of the available selection options. Singulation is the default configuration. Descriptions of the Train and GAP Train modes can be found in the chapter “Selecting the ZPA Mode”.

Clicking “Run” causes the motor roller of the zone to run in the preset direction.

Clicking “Accumulate” puts the zone into accumulation mode: The next load that reaches this zone is stopped and held there until the button is clicked again to cancel accumulation mode.

Choosing a new setting from the “ZPA Mode” drop-down menu changes the mode of the zone with immediate effect. If you wish to set all of the upstream zones for the train of nodes that you have entered in the “Node No.” fields, click “Set All”.

You can also proceed in the same way in the “Downstream Zone” area of the main window to adapt the settings for the downstream zones.



59

8.4.5. Selecting ZPA mode

Singulation mode is the default configuration for all zones after the auto configu-ration procedure has been carried out. A description can be found in chapter “Singulation (ZPA)”. The ZPA modes that are available via ECShell are described in the following.

Train Release mode

For zones that are configured for Train Release mode, all upstream zones are set in motion simultaneously when the downstream Train Zone is enabled. In this way, the motor roller conveyor operates in a similar way to a conventional roller conveyor with a single drive: All loads are moved at the same time. Figure 33 shows a typical example of Train Release.

Figure 33 “Train release” example

INFORMATION

Note that singulation and train release modes are configured per zone and a mixture thereof can occur in the same network.

GAP Train Release mode

Gap Train is a variant of the Train Release and contains a fixed delay before the loads are moved. Gap Train is typically used in the discharge zone of a zone group that is already in Train mode. This configuration can be used in order to ensure that there is a certain minimum distance between boxes.

Assuming that the gap timer in the discharge zone is set to 5 seconds and there are 10 zones behind the discharge zone that are all in train mode. All zones are occupied and accumulated. A box is released from the discharge zone. All boxes in all 10 zones now move simultaneously, since they are in Train mode.


60


As soon as the first box has passed the vicinity of the photo sensor, the gap timer starts. The next box arrives in the discharge zone and is stopped there until the gap timer has elapsed. When the gap timer has elapsed, the discharge zone is released and the train of boxes in all 10 upstream zones will start to move again simultaneously.

If you choose “Gap Train” in the “ZPA Mode” drop-down menu, the “Gap Timer” input field and the “Set” button are activated. Enter the required time value and click “Set” to update the value in the selected node.

INFORMATION

Gap Train mode is designed for use in the discharge zone of a zone group that is in train mode. If several successive zones are configured as Gap Train, a wait will occur in each of these zones for the duration of the respective Gap Timer. Depending on the time setting, the result may be very similar to “Singulation” mode.

T-bone configuration

In conveyor applications, special raising and lowering mechanisms are often needed to transfer a load at right angles from one conveyor belt to another. In other applications, a conveyor can simply transport its load from its downstream zone directly into the upstream zone of another conveyor arranged at a right an-gle. This configuration is generally known as a T-bone arrangement.

The ECC-DFC fieldbus controller contains the logic for controlling a T-bone ar-rangement without the need for an external controller interface or programming. Figure 34 shows the type of T-bone arrangement that is possible with the ECC-DFC fieldbus controller without an external interface.

Figure 34 Typical T-bone configuration



61

NOTICE!

Some aspects of material transport, such as the speed of the discharge convey-or and the weight of the load, must be carefully analyzed before using a T-bone configuration.

Be sure to check the mechanical design and the load characteristics before start-ing up a T-bone arrangement.

Connecting modules of a fieldbus controller for a T-bone arrangement

A T-bone arrangement can be started up in one of the following ways:

Sending and accepting zones are on the same module

Sending and accepting zones are on different modules

Figure 35 and figure 36 show the two ways of connecting the motor rollers and photo sensors to the modules of the fieldbus controller for obtaining a correct T-bone configuration.

Figure 35 Single ECC-DFC T-bone example


62


Figure 36 Two ECC-DFC T-bone example

In order to configure a T-bone arrangement in such a way that it works properly, the “T-zone Accept Time” in the main window must be set to a non-zero value. This time value is the delay of the rollers in the accepting zone so that the up-stream sending zone can transport the load onto stationary rollers in the accept-ing zone. When this timer has elapsed, the rollers of the accepting zone start up again on the basis of normal downstream conditions. A value of 200 milliseconds is typical for the nominal speeds of motor roller systems.

Enter a value, e.g., 0.200 for 200 milliseconds, and click “Set”. It depends on the accepting zone as to whether you modify the value of the upstream or down-stream zone in the main window. The “T-zone Accept time” always relates to the accepting zone.

Ignoring jam settings

Each zone can be configured so that it ignores the automatic reset delay, either for one or both determined jam statuses.

These jam statuses are described in the chapter “Jam statuses”. Choosing one of these options will not suppress the determination of the jam status; it will only suppress the preset time delay until the logic remedies the status automatically.

Assuming the jam timer is set to 5 seconds. If the sensor for a certain zone re-mains blocked after the zone has run for 5 seconds, it is stopped and a sensor jam status is indicated. In the default configuration, the sensor must be clear for 5 seconds (same value as the Jam Timer setting) before the zone automatically switches to automatic mode.



63

If the “Ignore Jam Sensor” check box has been activated, when the sensor is clear again, this 5-second delay is not used and the zone immediately switches back to automatic normal operation as soon as the sensor is clear.

A similar situation applies to the Arrival Jam: If a load is moving from the up-stream to the downstream zone, the logic expects it to arrive in the downstream zone within the time set in the Jam Timer.

If the load does not arrive within this time window, an Arrival Jam is indicated. Once the Arrival Jam has been determined, the zone is released again by default when the time value set in the Jam Timer has elapsed. If the “Ignore Arrival Jam” check box is activated, the logic does not wait for the additional delay time and the Arrival Jam Status is automatically reset immediately after it has been deter-mined.

If one or both check boxes are activated, the logic of the zone ignores the reset delay for the respective jam status.

8.4.6. Motor roller settings

The two biggest areas of the main window are for “Left Zone” and “Right Zone”. They display settings for the motor rollers and the overall status. They also allow you to modify the motor settings.

Motor type

The “Motor Type” drop-down menu contains all motor brands and models whose profiles are available for ECC-DFC. “ECR_Boost” is the default setting after the auto configuration procedure has been carried out. The new settings are down-loaded to the selected node.

Clicking “Set All” downloads the selected setting to the left-hand zones of all modules that are in the vicinity of the node entered above in the main window (“Node No”). If values of 5 and 12 have been entered in the “Node No” fields, for example, the choice in the “Motor Type” drop-down menu leads to a change to node 5, and clicking “Set All” changes nodes 6 to 12 to the same setting as node 5.


64


INFORMATION

If you are uncertain with regard to the motor type setting that is used, look this up in the motor roller documentation and check your application.

Braking method

The "Brake Method” drop-down menu contains all braking methods for motor rollers that are available for the ECC-DFC fieldbus controller.

“Normal” is the default setting the auto configuration procedure has been carried out. The new settings are downloaded onto the selected node if a new entry has been selected from the list. Clicking “Set All” downloads the selected setting to the left-hand zones of all modules that are in the vicinity of the node entered above in the main window (“Node No”).

If values of 5 and 12 have been entered in the “Node No” fields, for example, the choice in the “Brake Method” drop-down menu leads to a change to node 5, and clicking “Set All” changes nodes 6 to 12 to the same setting as node 5.



65

The following table describes the available braking methods for motor rollers:

Method Description

Normal Standard dynamic braking – the motor roller power circuit in the ECC-DFC is connected internally during the motor stop sequence in order to supply backwards-directed energy so that the rotor is braked. If the ECC-DFC determines that the motor has been stopped, the winding current to the motor roller is shut off completely. This is the industrial standard braking method for motor rollers and the ex works presetting for all zones by the auto configuration procedure

Free The motor roller power circuit in the ECC-DFC is interrupted internally, meaning that the rotor can rotate freely (“free spin”) until its mechanical load brings it to a standstill.

Servo Brake 1

If a zone is to be stopped, the ECC-DFC uses the Hall sensors of the motor roller to determine the position of the rotor and feeds current into the motor windings in order to maintain the rotor position. Servo brake 1 uses 2 of its power transistors for feeding in current.

Servo Brake 2

If a zone is to be stopped, the ECC-DFC uses the Hall sensors of the motor roller to determine the position of the rotor and feeds current into the motor windings in order to maintain the rotor position. Servo brake 2 uses 3 of its power transistors for feeding in current.

INFORMATION

The operating principle of servo brake 1 and servo brake 2 is identical. Servo brake 2 uses more power and provides a greater holding torque. The use of ad-ditional current by servo 2 means that there is a risk of heat build-up. If servo brake 1 provides sufficient holding torque for the application, it is advisable to prefer this method for servo brake 2. Servo brake 2 should only be used if servo brake 1 does not supply sufficient holding torque for the application.

Speed

The speed is set in meters per second (m/s). The ECR motor roller receives data regarding its gear step-down ratio and the roller diameter, which can be read from the ECC-DFC. The ECShell engineering software then uses this information to display whether the speed that you enter is permissible for the roller that is connected.

The motor roller gear step-down can be determined from the part number of the motor roller, which is displayed when you move the mouse over the module diag-nosis window. Further information about determining the nominal speed and the permissible speed range for a certain part number can be found in the ECDriveS® catalog.


66


For example, the motor roller information in figure 32 shows that the nominal speed of the motor roller that is connected to the module is 60 m/min or 1 m/s.

Entering a value of “1” for the speed and clicking “Set” sets the speed of the roll-er. If the background of the speed entry field remains white, it is a permissible speed value.

For our example roller, a speed of 2 m/s is above the maximum permissible speed. The background of the input field turns red and therefore indicates that the entered speed is too high.

For our example roller, a speed of 0.1 m/s is below the permissible minimum speed. The background of the input field turns blue and therefore indicates that the entered speed is too low.



67

Motor direction of rotation

The direction of rotation can be chosen here, which is either clockwise (CW) or counter-clockwise (CCW). This setting is determined for each module based on the results of the auto configuration procedure. The term “Motor direction of rota-tion” is defined in chapter “Definition of motor direction of rotation”.

This setting is available because some applications require the motor roller to be installed in such a way that the motor roller cable is on the opposite side of the conveyor belt, i.e., opposite the module.

Note that there is no “Set All” button for the motor direction of rotation, since the motor direction of rotation is defined during the auto configuration procedure.

Acceleration/deceleration

The acceleration and deceleration for a certain motor roller can be configured. The value of the distance traveled in revolutions is used for this. The preset ac-celeration value is 30 mm and the preset deceleration value is 30 mm.

Acceleration values can be between 0.03 meters (30 mm) and 10 meters. The braking values are limited to 0 to 10 meters.


68


8.5. Advanced dialog

The advanced dialog has already been mentioned in the section entitled “Use of the network help program”. The other selection options in this dialog window are described in the following.

To call up the advanced dialog, simply press the following pushbuttons:

F2

or

[Shift] + [Ctrl] + U

The node that is entered in the first field when you press [SHIFT] + [CTRL] + U or F2 is the node to which the settings in the advanced dialog relate.

8.5.1. Look Ahead and Timing

The default tab of the advanced dialog contains the Look Ahead and Timing set-tings.

Look Ahead function

The Look Ahead function configures the logic for “looking ahead” into the next downstream zone. If this zone is occupied when a load appears in the current zone, the module dynamically adapts the motor roller speed to the selected speed. This function is particularly useful in applications with faster speeds in which a greater braking distance is required. Loads can be prevented from run-ning past their stop positions in this way.

The function can be used zone-wise or for the entire system.

Figure 37 Normal run before Look Ahead function starts

In figure 37 the conveyor belt is running at the speed that has been configured for the module by the auto configuration procedure or at a manually entered speed.



69

Figure 38 Look Ahead function starts

Figure 38 shows how a box passes the photo sensor of zone C and the module of zone B automatically adapts the speed to the previously configured Look Ahead speed.

Activate the check box to enable the Look Ahead function for the selected node. Clicking “Set” loads this setting for the respective zone in the selected node. The entered value for the slowed-down speed is a percentage of the speed of the node that has been set in the main window.


70


In this example, the slowed-down speed is proportional to 50% of 0.5 m/sec. De-tailed information about the “Slow Down” and “Fast Release Time” functions can be found in the pop-up window of the ECShell engineering software.

Clicking “Set All” activates the Look Ahead function in the entered % speed for all nodes in the area that is defined in the main window.

INFORMATION

Detailed information about the “Slow Down” and “Fast Release Time” functions can be found in the pop-up window of the ECShell engineering software.

The jam timers are used by the logic as the anticipated time that a load requires to run from one zone to the next. If this timer elapses before the load reaches the next zone, the module indicates a jam condition. The jam condition of a zone is automatically canceled and the jam timer starts as soon as the photo sensor of the zone is clear.

”Jam”, “Auto Clear”, and “Run After” timers

If a zone is in the jam condition and its photo sensor remains blocked, the vicinity of the photo sensor must be cleared and remain free for the time that is set in the jam timer. If a jam occurs in a certain zone, the logic prevents upstream loads from running into this zone.

The default value for the jam timer is 5 seconds and the permissible range of values that can be set for each jam timer is between 1 and 20 seconds.

The Auto Clear timer determines the time for which the module waits before it attempts to clear a jam.

The logic uses the value of the Run After timer for normal zone discharging. It is the time for which a motor roller of a zone should continue running when the pho-to sensor is clear again after the load has been passed to the next downstream zone.

This additional running time allows the zone to continue running until the rear edge of the box has entirely passed the photo sensor and has run all the way into the next zone. The value of this timer is adjustable in order to compensate for special conditions in which the photo sensor of a zone has to be attached in a position that is further upstream or downstream.

The default value for the Run After timer is 0.4 seconds, the setting range of the Auto Clear timer is between 0 and 10 seconds, and the permissible range of val-ues that can be set for each Run After timer lies between 0.1 and 6 seconds.



71

Clicking the “Set” buttons for the Jam timer or the Run After timer results in the entered setting being downloaded to the respective zone of the selected node. Detailed information about the settings and functions of the Jam timer and the Auto Clear timer can be found in the pop-up window of the ECShell engineering software.

Clicking “Set All” for the Jam timer or the Run After timer results in the entered values being used on all nodes of the range defined in the main window. Detailed information about the settings and functions of the Jam timer and the Auto Clear timer can be found in the ECShell engineering software.


72


8.5.2. Upgrade

The firmware help program can be accessed via the Upgrade tab. As time goes by, improvements and new functions are added to the product series. These must be loaded onto the modules via firmware upgrades.

Firmware upgrades are files that are sent to you or made available for download-ing. The upgrade help program allows you to search for these files and then load them onto individual selected nodes or an entire group of nodes.

If you have selected the Upgrade tab, ECShell enters the IP addresses of the node range entered in the main window. Click “Browse” to open a dialog window for file selection.



73


74


When the “Open” dialog window is displayed, navigate to the directory in which you have stored the firmware update file. Select this file and click “Open”.

In this example, “Upload ALL” has been clicked, meaning that the firmware up-grade file is sent to all 6 nodes. The “Output” window displays the progress of the upload procedure. The duration of the procedure depends on the number of nodes that are updated.



75

When status of “Done” appears in the “Output” window for all nodes, the proce-dure is complete and you can close the Advanced dialog.


76


8.5.3. Connections

The Connections help program uses ECShell in order to instruct a certain module to establish a logical connection with another module that it would otherwise not have established during the auto configuration procedure. In applications with more than one subnetwork, the node of a subnetwork the is furthest downstream is logically linked with the node of another network that is the furthest upstream in this way.

Connecting two networks with each other

Figure 39 shows a typical delimitation between two subnetworks. The node of the first subnetwork that is the furthest downstream has IP address 192.168.27.25, and the node of the second network that is the furthest upstream has IP address 192.168.25.20.

Figure 39 Example of delimitation between two subnetworks

By connecting a crossover Ethernet cable between these separated nodes and using the ECShell engineering software to set up the “logical” connection you can achieve a smooth flow of information between the two networks. This is shown in figure 40.

Figure 40 Example of separated subnetworks with cable

The procedure requires that you instruct node 192.168.27.25 to transport the load to node 192.168.25.20. You also have to instruct node 192.168.25.20 to accept the load from node 192.168.27.25.



77

INFORMATION

The following example requires the PC to have access to several subnetworks. More information can be found under Appendix B – configuring the PC for Ether-net subnetworks.

Configuring node 192.168.27.25

1. First enter the correct subnetwork into the “Network IP” fields in the main window, plus the correct node that you would like to connect. In this case, xxx.xxx.xxx.25 is node 6 for this special subnetwork.

2. Call up the Advanced Dialog and select the “Connections” tab.

Note that the relevant node is displayed in the middle and that this field is

deactivated. In addition, the designation “None” is displayed under “Downstream”.

The downstream flow should then be changed to IP address 192.168.25.20, which is the next downstream node.

3. Click the button for the IP address, enter the correct value, and click the “Apply” button.

Note that it takes about 20 seconds for the module to accept the change. The

module is then automatically restarted.


78


The procedure is now half-way through. Then instruct the downstream module to accept the load from the upstream module, as described in the following.



79

Configuring node 192.168.25.20

1. First enter the correct subnetwork into the “Network IP” fields in the main window, plus the correct node that you would like to connect. In this case, xxx.xxx.xxx.20 is node 1 for this special subnetwork.

2. Call up the Advanced Dialog and select the “Connections” tab.

Note that the relevant node is displayed in the middle and that this field is

deactivated. In addition, the designation “None” is displayed under “Upstream”.

Now instruct this node to accept loads from IP address 192.168.27.25, which is the next upstream node.

3. Click the button for the IP address, enter the correct value, and click the “Apply” button.

Note that it takes about 20 seconds for the module to accept the change. The

module is then automatically restarted.

The procedure is now complete, and loads can flow from node 192.168.27.25 to node 192.168.25.20.


80


8.5.4. Network Services

The Network Services window is used both for checking for reachable networks and also for setting the IP address of a selected module. For more information, refer to the "Use of the network help program" section.

8.5.5. Special Services

Each module operates a runtime meter for each motor roller that is connected to the module. The value of the runtime is displayed as the Operating Time in the main window. This window in the Advanced Dialog allows you to reset the runtime meter when a motor roller has to be replaced.

Another function in the Special Services window is a button for remedying a mo-tor roller short circuit. This particular fault cannot be remedied via the logic using a timeout time or similar restart. A motor roller short circuit requires the module to be switched off and on again or the “Reset” button to be pressed in this window. This function is provided in ECShell in order to make the procedure easier and prevent the module from having to be switched off and on again.

The final function in the Special Services window is “Touch and Go”. When this function is activated, the motor roller detects movements on the roller surface and transmits a wake-up signal in the relevant zone. If, for example, a box is placed in the zone and gently pushed in the flow direction, the zone wakes up automatical-ly. The function can be activated for both upstream and downstream zones using check boxes in each case.

8.5.6. Use of sensor connection Aux I/O Pin 2

The function of pin 2 of the M8 connector at each of the two sensor connections of a module is configurable. This pin can be used either as an input or an output. The factory default setting for pin 2 is “Not Used”. One of the following functions can be selected for each zone of the module via the “Pin 2 Usage” window from the Advanced Dialog:

None: Ignore every input signal at pin 2

Accumulate: Input for local zone accumulation command

Wake up: Input for local zone wake-up signal

Lane Full Interface: Input for “Lane full” interface signal

Module error output

“Product in Zone” output

Sensor error output

Depending on how the module is configured, you can select which of these func-tions should be present at which of the pin 2 signals of the two sensor connec-tions.



81

In this example, the left-hand pin 2 has been set as a “Wake up” input for the upstream zone of the module, and the right-hand pin 2 has been set as a “Lane Full” interface for the downstream zone.

Note that the green arrows specify the zone (UP or DOWN) that has been as-signed to the function of the left or right pin 2.

Also note: If “Lane Full Interface” has been activated at a pin 2, the “Block” and “Clear” timer selection is displayed. In the example, 3 seconds has been set for the “Block” time and 4 seconds for the “Clear” time.


82


In this example, the same functions have been retained for pin 2, but this time the arrow has been selected that points diagonally from right-hand pin 2 to the up-stream zone (UP). This leads to a situation whereby the setting for pin 2 (“Lane Full Interface”) is applied to the upstream zone rather than the downstream zone.



83

In this example, a typical zone “handshake” has been set for the upstream zone of the module. The left-hand pin 2 signal is the input that “wakes up” the zone and the right-hand pin 2 signal is an output that indicates that the upstream zone is occupied.


84


In this example, a typical zone “handshake” has been set for the downstream zone of the module. The right-hand pin-2 signal is the input that instructs the re-lease of the downstream zone, and the left-hand pin 2 signal is an output that indicates that the downstream zone is occupied.



85

In this dialog, you can also invert the meaning of the electrical signal by activating the “Invert” check box for one or both of the pins. Since the “Invert” check box is selected for both pin signals in the example that is shown, the respective func-tions are not activated until the signal has been electrically switched off.

Note that the invert function works in a similar way for the output signals. If the “Product on Zone” function has been selected, the electrical signal is switched off if the Invert check box is activated and the zone is occupied. The electrical signal is switched on if the check box is activated and the zone is free.


86


8.5.7. Flex Zone

ECC-DFC modules detect automatically if a box is longer than a zone length and automatically adapt the accumulation control so that the longer box occupies two logical zones. This prevents a collision between the following box and the longer box. “Flex Zone” mode operates in both “Singulation” mode and “Train Release” mode. This tab allows you to either activate or deactivate the function.

NOTICE!

Note that the “Flex Zone” function must be activated or deactivated for the entire subnetwork. It cannot be activated or deactivated for individual zones or zone groups in the same subnetwork.

8.5.8. Sensors

The sensor table shows how the sensor has been configured during the first auto configuration of the system. If, for example, all sensors in the system are stimu-lated by light and are “light energized normally open”, the sensor of the relevant zone will indicate “off blocked”. Use this tab to modify the default configuration of the sensors for each module and adapt it to the given circumstances.

INFORMATION

More information about changing the sensor status or a sensor error status after auto configuration can be found in the self-help dialog window of the ECShell engineering software.



87

8.5.9. Extensions

The “Extensions” tab allows you to extend individual zones or multiple zones into a “Master” zone or subordinate them to such a zone. To do this, go to the up-stream or downstream node of the module that you would like to extend and se-lect “This module (current node) is an extension of the downstream or upstream module (node up to which you would like to extend the current node)”.

Additional information can be found in the ECShell engineering software.

10. Appendix B – Configuring the PC for Ethernet subnetworks

10.1. IP addresses and subnetworks

In order to connect to a network and/or use and control a conveyor system with several subnetworks, a certain amount of knowledge about Ethernet IP address-es is required. This section gives you some background information and provides a brief instruction concerning the configuration of your PC so that you are able to gain maximum benefit from the ECC-DFC fieldbus controller and the ECShell engineering software.

The IP address of the PC is used by an Ethernet network to identify the PC in the network. An IP address consists of 4 numbers or octets. Each number can con-sist of a value from 0 to 255. The format of an IP address is:

AAA.BBB.CCC.DDD

Whereby AAA, BBB, CCC, and DDD can theoretically be a value between 0 and 255. Each PC in a network has a unique IP address. The AAA value identifies the class of the network and is especially relevant for IT experts and other parties such as Internet providers etc. For the purpose described here, a class C network is used that has a value of 192 for AAA. 168 is the BBB value. The two octets 192.168 for AAA.BBB are the most commonly used ones for user-configurable networks. The values AAA.BBB.CCC identify the subnetwork to which the PC is connected.

Think of the subnetwork as a group of PCs or modules that can all communicate directly with each other. If, for example, the subnetwork IP address (AAA.BBB.CCC) of a PC is 192.168.0, every other PC or every other device on the network whose subnetwork is also 192.168.0 can communicate with the oth-ers. In this case, our network can consist of 256 devices, since the DDD octet must be within the range of 0 to 255, and each complete IP address may only occur once. Each other PC or module in our network whose subnetwork is not 192.168.0 cannot communicate with the others.

In order to put the PC in a position to communicate with more than 256 possible addresses in the network, the IP address configuration of the PC uses another 4-octet value that is known as the subnet mask. This value allows the PC to recog-nize other subnetworks in the same network.

The following figure shows some typical values for subnet masks and the result-ing number of subnetworks that can be addressed:



91

Figure 41 Available subnetworks for each typical subnet mask value

As you can see, it is possible to configure the PC using simple subnet mask val-ue manipulation so that it recognizes several networks.

10.2. Configuration example

The IP address of the PC is used by the Ethernet network to identify the PC in a network. In the majority of office networks, the IP address is automatically as-signed by the office network; in smaller networks (such as home networks), the IP address is issued by a router. In some cases, your IT department assigns a fixed IP address to your PC or laptop.

In this example, communication is to take place with up to 4 separate subnet-works. With a correctly configured PC, you can use the ECShell engineering software to examine and modify the parameters for all modules in all 4 networks.

The following figure shows how the IP address settings of the PC should be con-figured:

Figure 42 Example of IP address configuration


92


INFORMATION

The structure of the ECC-DFC IP addresses is designed such that the final octet (DDD) of all modules is greater than or equal to 20 and less than or equal to 240. This means that 36 valid addresses (256 - 220 = 36) are left free in the same subnetwork for other devices such as PCs and PLC controllers. In our example the final octet of the PC's IP address has been set to 10. This could also be any other value from 0 to 19 or 241 to 255. Network conventions stipulate that the values 0 and 1 of the final octet (DDD) of a subnetwork are normally reserved for the standard gateway, often the address of an Ethernet router.

Also note that in our example, all possible subnetworks for the subnet mask that is shown (255.255.252.0) are used. From figure 44 above, every value for X in the diagram would have to be able to be selected that is listed above the value 252. In this case, simply more subnetworks would have been available for ad-dressing.

10.2.1. Changing the IP address of the PC

To change the IP address of the PC, click Start – Control panel – Network Connec-tions – Local Area Network. The “Local Area Connection Status” window is then displayed. Click Properties in this win-dow.

The “Local Area Connection Properties” window is displayed. Scroll down in the selection window and click once to select Internet Protocol (TCP/IP). Click the Properties button.



93

When you click Properties, the “Internet Protocol (TCP/IP) Properties” window appears. In this example it has been as-sumed that an IP address has been as-signed to your PC by your office network. This is also indicated by the fact that the text fields in this window have been deac-tivated. Select "Use the Following IP ad-dress” and the text fields are activated again so that entries can be made.

In this example, the value of the IP ad-dress, the subnet mask, and the standard gateway must be entered. Click OK so that the settings are made. Note that a value has been entered in the default gateway field. This is only necessary if your network has a specific router. In the majority of cases, this value is the same subnetwork as the IP address field, and its final octet (DDD) is normally 0 or 1.

INFORMATION

Contact your IT department if you are uncertain with regard to modifying the IP address of the PC.

If you enter values for the IP address, subnet mask, and standard gateway for the PC under point (5), be sure to note the previous values before clicking the button under point (6). As soon as you click “Use the following IP address” under point (6) these values are lost!

If you have completed the communication with the network(s) and have to reset the PC to the previous network settings, simply use the same procedure and enter the noted-down values again.
