I am trying to connect an Allen Bradley PLC to a FANUC Robot that has the Ethernet/IP option available.

We are able to do ping.

The robot's IP is seen on RSLinx Classic, but whenever we try to register the generic module we receive the following error:

Invalid conection point.

The module settings we are using are in the attachments of this thread.

Robot version is 6.4
PLC is an 1756-L73
Controller is an RJ3iB

Does anyone have an idea on why we are not able to register the module?

Did you enable the ethernet ip connection in the robot? On the newer robots it is under the IO menu. Ping works even if the EIP connection is disabled.

Yes, we were following a guide to set this up. But we still don't manage to successfully register the module on RSLinx.

I will attach screen pictures from the TP, maybe we set up something wrong or we are missing something?

Your settings look correct. Here is a previous thread where someone had an AB plc connection issue, might be helpful. Another thing I have seen work sometimes is to delete and recreate the generic ethernet module in the PLC.

Check your RPI settings and eds file.

EDS file is not required for Generic Ethernet Module.
From the screenshots it looks like no connection.
Ensure the PLC program as shown is downloaded and running.
Use straight cables if connecting via switch and cross-cable for direct connection.
Use the Ethernet Port2 of the robot. Configure its IP address properly and it cannot be on the same subnet as the Port1.
The Router Address in the port configuration is Default Gateway.
Do not confuse the Port1(CD38A) and Port2(CD38B) with the CD38C port below on the controller.
Cycle the robot power after the Port or I/O or EtherNet/IP configuration changes.
