Integrate a SIG200 Ethernet/IP into a Beckhoff PLC

We connected a SIG200 with Ethernet/IP to a Beckhoff PLC with the help of a EL6652 terminal which enables communication from EtherCAT to Ethernet/IP.

The following points are important to take into consideration while integrating the device:

Step 1: The EL6652 terminal from Beckhoff can not send configuration data to any of the EIP devices connected to it. Only process data from slaves connected to the network can be read/written.

Step 2: The SIG200, configuration must be previously done via SOPA ET or SOPAS Air (WebServer), an IP Address must be assigned within the network of the EL6652. The EL6652 will NOT assign an IP address on the SIG200.

Step 3: All ports of the SIG200 must be configured to have Fieldbus as their port owner.

Step 4: Go to Twincat and import the EDS file to the project via right click on the EIP scanner

Step 5: Add the imported EDS file to the project and give it a name.

Step 6: Assign the IP address to the SIG200 which you gave via SOPAS

Step 7: Add IO Connection “Input Only”, click yes to create variables and confirm the following configuration:

Step 8: After doing this, assign the IP address to the EL6652.

Step 9: Afterwards, go to your PLC task and define the following variable

Step 10: Now build the project and link the variable to the EL6652 state variable:

Step 11: Now transfer your configuration and set the PLC in Run mode. When the configuration has been transferred, the process data should be seen on the IOL Inputs X variables. In my test scenario I am using a WTT12 with 4 bytes of process data:
