1 Introduction

1.1 System configuration and purpose of the white paper The purpose of this document is to present an application example for commissioning and programming a SERVOLASER Xpert positioning sys-tem, hereinafter referred to as "Xpert". References are made to the corre-sponding installation and operation manual (MAN-1282 Rev 4-en-GB) [1].

The hardware of the test system for commissioning consists of the follow-ing:

• SERVOLASER Xpert SLX-S-M-2-1-2-L1-D4-1,7-IE-1-1 • IndraLogic XLC L45 model CML45s-XLC-13V12.0573.001 • HP PC with 8 GB RAM and Windows 7 Professional

The following programming software is used:

• IndraWorks ML* 13V12.0079.07 • BOOTP/DHCP Server 2.3

The components used and the system configuration are shown in Fig. 2-3.

IndraLogic XLC L45PC

Ethernet



The Xpert has its own controller with an Ethernet/IP port and two movable laser modules (Fig. 1-2). Two devices can be connected to form a system with up to four movable lasers.

An additional fixed laser, which is installed in the centre, is optional. This fixed laser is positioned above the linear rail. This enables the movable la-ser modules to use the entire travel range.

Three different laser colours are available, i.e. can be configured (red, green, blue). The laser colours can be combined in any way. Maximum visibility in different lighting conditions and on different projection surfaces can be ensured by the choice of laser colour.

The laser modules are available with different aperture angles. The stand-ard aperture angle is 90° for red and green lasers and 70° for blue lasers.

The different laser classes provide different levels of laser power. The maximum possible laser output power of the Xpert is 40 mW. Models with a maximum laser output power corresponding to the permitted limit are available for each laser class. The dimming function allows you to set each individual laser module separately to your optimum visibility.

This white paper is structured to follow the procedure during commission-ing. In principle, a different sequence of steps would be possible in some places, but a modified order of steps during Ethernet/IP configuration and the assignment of IP addresses has generally led to problems. Therefore, it is recommended that you adhere to the sequence of steps specified here.

First you must connect the Xpert directly to the programming PC. This step is necessary because when the Xpert is subsequently connected with the PLC, you will no longer be able to access the integrated web server. Then you assign an IP address for the programming PC and the Xpert as well as check the Ethernet/IP connection.

In the second step, download an electronic data sheet (EDS file) of the Xpert via the Xpert web server. The EDS file contains all communication parameters of the device as well as the available objects. The DeviceNet configuration tool imports the EDS files of the devices available in the net-work and uses them to calculate the configuration data which are subse-quently loaded onto the DeviceNet participants.

In the third step, connect the system cables as shown in Fig. 1-1. You then assign an IP address for the programmable logic controller. After that the IP address of the programming PC must be adapted to the IP address of the PLC.

In the fourth step, create a new IndraWorks project and add the hardware. Select the IndraLogic XLC L45 used here as the device type and define the IP address. Only the two real-time Ethernet interfaces X7E3/X7E4 are needed for the interfaces. Next to the port designation, select an Ether-net/IP scanner, which functions as a master here. Once you have com-pleted the configuration, you must set the Ethernet/IP scanner parameters and import the previously downloaded EDS file.

The last chapter of the white paper shows an application example for con-trolling the movements. It deals with the creation of a variable table for controlling the incoming data packets and for reading the outgoing data packets of the Xpert. It also describes the procedure for loading the project onto the programmable logic controller.

All steps from configuring the Ethernet/IP to creating the finished program are described in detail in the following chapters.



2 Configuring the Ethernet/IP connection

2.1 Assigning an IP address for the programming PC First you must connect the Xpert directly to the programming PC as shown in Fig. 2-1. This is the only way to access the integrated web server of the Xpert and download the EDS file.

Fig. 2-1: Connection between Xpert and programming PC

To assign IP addresses, in this case the IP address of the Xpert, you must first appropriately set the IP address of the programming PC. In this appli-cation example the IP address 192.168.200.20 was assigned to the pro-gramming PC. This is done as shown in Fig. 2-2:

Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings > Local Area Connection > Properties – Internet Protocol Version 4 (TCP/IPv4) > Properties > Use the following IP address: 192.168.200.20 > OK

2.2 Assigning an IP address to the Xpert using BOOTP/DHCP Server Next, assign an IP address to the Xpert via the BOOTP/DHCP Server software. When the BOOTP/DHCP Server 2.3 software is started, it scans the MAC addresses of all connected devices (Fig. 2-3). The identified par-ticipants and their MAC addresses are displayed in the Request History window. Select the Xpert MAC address and click Add to Relation List to confirm.

Fig. 2-3: Search for the Xpert MAC address using BOOTP/DCHP Server 2.3

Then BOOTP/DHCP prompts you to enter the IP address (Fig. 2-4), which must be in the same subnet as the programming PC. In our application example IP address 192.168.200.21 was assigned to the Xpert. If the en-try has been confirmed, the MAC address and IP address are displayed in the Relation List window. If everything was successful, the [Enable DHCP] Command successful message is displayed in the Status window at the bottom left of the screen (Fig. 2-5).

Following this message, a ping can be sent from the DOS window to the Xpert to check accessibility (Fig. 2-6).

2.3 Downloading the Xpert EDS file In order to include the Xpert EDS file in the IndraWorks project later, you must first download it from the integrated Xpert web server. To do so, open a web browser and enter the IP address of the Xpert (see chapter 2.2) as the web address.

Right-click the file and select Save target as to download the EDS file (Fig. 2-7 and Fig. 2-8).

Fig. 2-8: Downloading the Xpert EDS file



2.4 Cabling and configuration of the overall system After you have successfully downloaded the EDS file from the integrated web server, connect the cables of the overall system as shown in Fig. 1-1. Then set the Ethernet X7E5 programming interface to which the pro-gramming PC is connected to the programmable logic controller using the arrow buttons (Fig. 2-9) [2,3]. In our application example IP address 192.168.1.32 is assigned to the programming interface. It is important that this IP address be located in a different subnet to the IP address of the Xpert, since otherwise IP communication conflicts could occur.

Fig. 2-9: Configuration of the Ethernet X7E5 programming interface

Then you must reassign the IP address of the programming PC in the subnet of the programmable logic controller. The procedure for assigning a new IP address to the programming PC is described in chapter 2.1. In our application example the new IP address 192.168.1.10 is assigned to the programming PC. Tab. 2-1 shows all assigned IP addresses and the corresponding systems.

Tab. 2-1: All assigned IP addresses



3 Creating an IndraWorks project If the cables of the overall system have been connected and an IP ad-dress has been assigned to each system, you can then open the In-draWorks software and create a new project [4,5]. In the Project Ex-plorer in the left column, right-click the project name and select Add > IndraLogic XLC L45 (Fig. 3-1).

Fig. 3-1: Creating a new project in IndraWorks



This automatically opens a window for configuring IndraLogic XLC L45 (Fig. 3-2).

In the Step 2: Configuration window, specify the firmware version as well as the IP address and type of the device. The IP address was already as-signed in chapter 2.4 and must only be copied to the software. In our ap-plication example IP address 192.168.1.33 is entered. You can then exe-cute a connection test in this window.

Fig. 3-2: Configuring IndraLogic XLC L45

When you have copied the settings and successfully executed the connec-tion test, you configure the ports in the next window, Step 3: Interfaces (Fig. 3-3). In our application example only the two Realtime Ethernet interfaces X7E3/X7E4 are needed. In the selection list next to the port designation, select an Ethernet/IP Scanner, which functions as a master here. Then click Finish to complete the configuration.



Fig. 3-3: Configuring the interfaces

You have successfully created the project and now you can open it in the Project Explorer. The Ethernet/IP scanner was also created (Fig. 3-4). You need only to set its parameters.

Fig. 3-4: Ethernet/IP Scanner has been created successfully

Double-click the Ethernet/IP scanner to open the Scanner settings tab (Fig. 3-5). Select the Used fixed IP-Address: option. The IP address must be in the same subnet as the IP address of the Xpert. In our applica-tion example the address 192.168.200.100 is selected, since the address 192.168.200.21 was assigned to the Xpert in chapter 2.2.



Fig. 3-5: Configuring the Ethernet/IP scanner

After a new IndraWorks project has been created and the Ethernet/IP scanner has been configured, you can now import the Xpert EDS file. To do so, from the main menu select Tools and then the Device Data-base tab (Fig. 3-6).

Fig. 3-6: Opening the device database

You can install and uninstall device description files in the device data-base. The devices which are currently installed are listed in the Available devices section. To add a new device, click Add Devices (Fig. 3-7).



Fig. 3-7: Device database

First select the EDS and DCF files search option. Then select the Xpert EDS file and click Open to add it (Fig. 3-8).

Fig. 3-8: Opening the Xpert EDS file

The Xpert has now been automatically added to the list of available devic-es.



Fig. 3-9: Updated device database

To add the Xpert to the project, right-click the Ethernet/IP scanner in the Project Explorer and select the following path (Fig. 3-10):

Add > Add device > Generic Device > ServoXpert Ether-Net/IP

Fig. 3-10: Adding the Xpert to the project

The device has now been added. Double-click the ServoX-pert_Ethernet/IP in the Project Explorer to set the Xpert param-eters. The IP address here must match the configured address of the Xpert (Fig. 3-11). In our example, the IP address is 192.168.200.21.



Fig. 3-11: Configuring the Xpert

Then select the Connections tab and click Add Connection (Fig. 3-12).

Fig. 3-12: Add Connection

Here you must click the Exclusive Owner row. In the New connection window, make the following settings as shown in Fig. 3-13:

• Due to the program cycle time, set RPI to 20ms • Set the Target to Scanner text box to 256 bytes

Leave the default values for the remaining setting options.



Fig. 3-13: Connection settings

When you create a new connection with the settings shown, the input and output words on the EthernetIP I/O Mapping tab are also automati-cally created. The Always update variables option must always be ticked (Fig. 3-14). The definition and structure of the input and output data words for controlling and monitoring the Xpert are described in the rele-vant installation and operation manual (MAN-1282 Rev 4-en-GB). This ends the hardware configuration. The last chapter of the white paper shows an application example for controlling the Xpert.

4 Application example

4.1 Creating the variable table The Xpert can be controlled only byte by byte via the EthernetIP I/O Mapping of the Ethernet/IP scanner. For this reason a variable table is created in this step. With this table you can more easily and more conven-iently control and read the individual variables of the incoming and out-going data packets.

To create the table, in the Project Explorer double-click the PlcProg (PRG) module (Fig. 4-1).

Fig. 4-1: Creating the variable table in the PlcProg module

You declare the input and output variables in this module. The variables are described in the relevant installation and operation manual (MAN-1282 Rev 4-en-GB). Fig. 4-2 and Fig. 4-3 show the declared input and output variables.

Fig. 4-2: Declared output variables



Fig. 4-3: Declared input variables

4.2 Uploading the program to the PLC To upload the program to the PLC, you must first compile the program, transfer it and then click the Start button to launch it (Fig. 4-4).

Fig. 4-4: Uploading the program

Click the Build button to compile the project. Then click the Login but-ton to transfer the project to the programmable logic controller.

After that you can click the Start button to launch the program. You can now write the input variables of the Xpert online and copy them to the PLC by pressing the Ctrl + F7 key combination (Fig. 4-5).

Various parameters can be read via the Xpert output variables.

5 Summary This white paper presents an application example for commissioning and programming a SERVOLASER Xpert positioning system in connection with a Bosch Rexroth IndraLogic XLC L45 control system.

The first chapter describes the hardware and software used as well as the purpose of the white paper. It also provides general information about the Xpert.

The second chapter describes the settings of the Ethernet/IP connection on the programming PC as well as the assignment of IP addresses using the BOOTP/DHCP Server software. It then describes the downloading of the Xpert EDS file from the integrated web server to the programming PC. The last part of the second chapter describes the cabling and configura-tion of the overall Ethernet/IP network.

The third chapter describes the creation of a new IndraWorks project, which contains the configuration of the programmable logic controller, the configuration of the Ethernet/IP scanner which functions as the master, as well as incorporation of the downloaded EDS file in the IndraWorks pro-ject. In addition it describes the settings and adding of a new connection with the Xpert.

The last chapter describes an application example for controlling the Xpert. It deals with the creation of a variable table for controlling the in-coming data packets and for reading the outgoing data packets of the Xpert. In addition it describes the procedure for uploading data to the pro-grammable logic controller. In principle the Xpert and the Bosch Rexroth IndraLogic XLC L45 software have always worked together without prob-lems or errors when the Ethernet/IP protocol is used and when the rele-vant installation and operation manual (MAN-1282 Rev 4-en-GB) and the points described in this white paper are adhered to.
