I inherited a setup that has some OPC configured by a user that is no longer with the university. I'm trying to figure out how it was set up as we have now moved the server to a new subnet and things stopped working. I can't even tell for sure what software he was using as he had some Honeywell and some Rockwell pieces installed on the server. Any idea how I can determine what was being used and what I need to reconfigure for the new subnet? Any clues, hints, etc. would be greatly appreciated.
