    Access I/O on Moeller PS4 using OPC.

    Hello, guys! I want to access I/O from my Moeller PS4-341 to display data in a supervisory using OPC. I'm able to read/write marker variables on PLC, but I don't understand how I can access the I/O. Is there a way to do this by mapping I/O on markers or something like that? Thanks in advance :)
