I have been trying to connect to a PLC from PS 10.1 via an OPC connection.
The laptop PS is installed on, is connected with ethernet cable to a switch, and the network adapter of the PLC is also connected to the switch.
The problem is that PS client can't see the OPC server.
I have tried to install the OPC server on another machine, and connect it to the switch but, the result is the same, PS can't see the OPC server.
How can this connection be made?
