How to capture ethernet traffic / Modbus TCP

0

I installed WS on my computer. I want to see Modbus TCP traffic that is on the same network.

The Modbus TCP traffic is going from a Master PLC to other Slave PLCs, and does not communicate directly with the computer.

WS only seems to show traffic sourcing or sinking to itself (10.0.0.100).

I want to see the traffic between the PLCs (10.0.0.50 to 59).

How do I set this up?
