In this example program an EP3356 is addressed by a PLC program (for TwinCAT 2). The Zip-file (download) contains the PLC*.pro and the System Manager*.tsm. The box can be operated via simple visualization; the function InputFreeze is programmed out by way of example.

Example program 2: — Use of the example program

The EP3356 EtherCAT Box is to be connected as shown below:

Example program 3: — EP3356: Connection of the load sensor/full bridge

The sensor power supply of 10 V is produced in EP3356.

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 Manger and TwinCAT PLC will open
Connect the hardware in accordance with one of the two previous figures and connect the Ethernet adapter of your PC to the EtherCAT coupler / EtherCAT box (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); on the "Adapter" tab choose "Search...", select the appropriate adapter and confirm (see the following two figures)

Example program 4: — Searching the Ethernet adapter

Example program 5: — Selection and confirmation of the Ethernet adapter

Activation of the configuration and confirmation (see the following two figures)

Example program 6: — Activation of the configuration

Example program 7: — Confirming the activation of the configuration

Confirming new variable mapping, restart in Run Mode (see the following two figures)

Example program 8: — Generating variable mapping

Example program 9: — Restarting TwinCAT in Run Mode

In TwinCAT PLC, under the "Project" menu, select "Rebuild all" to compile the project (see following figure)

In TwinCAT PLC: log in with the "F11" button, confirm loading the program (see following figure), run the program with the "F5" button
