Or Screenshots of the PGPC Settings you have set? In the PGPC Seetings you can do a diagnose of the Connection and you can read out the devices on the bus. Try it and give us feedback what the result is. Wiring is also a topic. Bye Murof

Is the Interface of your PLC set to Profibus with the same Speed? (be careful in some S7300 you can select between MPI and DP on the Interface.) Bye Murof
