Now, I need to know how to see that addresses with some OPC? I do not know of any OPC setup that reads the Symbolic addresses of the s7-1200 PLC. I have always had to use absolute addressing in the 1200's to get it working. Is this the Siemens OPC product? If so, try out the Support Requestin case I am wrong since it would be a much better solution to use symbolic.
