Starting the example program

The application examples have been tested with a test configuration and are described accordingly.
Certain deviations when setting up actual applications are possible.

The following hardware and software were used for the test configuration:

• TwinCAT master PC with Windows XP Professional SP 3, TwinCAT version 2.10 (Build 1335) and INTEL PRO/100 VE Ethernet adapter
• Beckhoff EK1100 EtherCAT coupler, EL9190, EL2212 and EL9010 terminals.
• Feed 24 - 72 V DC into the EL9190

Procedure for starting the program

• After clicking the Download button, save the zip file locally on your hard disk, and unzip the *.TSM (configuration) and the *.PRO (PLC program) files into a temporary working folder
• Run the *.TSM file and the *.PRO file; the TwinCAT System Manager and TwinCAT PLC will open
• Connect the hardware in accordance with fig. 1 and connect the Ethernet adapter of your PC to the EtherCAT coupler (further information on this can be found in the corresponding coupler manuals)
• Select the local Ethernet adapter (with real-time driver, if one) under System configuration, I/O configuration, I/O devices, device (EtherCAT); then on the "Adapter" tab, "Search..." box, select the appropriate adapter and confirm (see corresponding illustrations)
