How to get sensor/variable data while controlling via PLC?

I would like to connect SIMATIC S7-1200 to UR3e. As a person who never used PLC before, I am still learning it, hence I have a question.

I need to record all network traffic between PLC and UR3e. I am thinking duplicating the traffic via network switch. What is the correct way of doing this?

I am not sure why you would want to do this but one tool that might be useful is WireShark.

The first method I would recommend (in general) for communicating to the robot would be ProfiNet, if using a Siemens PLC.

Update: The communication will be done over OPC-UA.

I guess I will go with these two: &
