Read Micro800 MAC address in program?

4 posts in this topic

Is the MAC address accessible in the program? Or any other unique identifier, e.g. serial number?

Do you want to check if the program has been loaded into a different PLC? It's easier to help you if you declare what you want to do in the end.

That's a potential application for another day.

Right now I'm looking to be able to uniquely identify which backup/settings came from which unit, as there are multiple units running the same program, but with parameters particular to that instance.

Have not seen if there is a hardware identifier available at program level, but maybe you can use the IP adress as one? Just guessing you have a static IP on each PLC, so that would give you way to differentiate them.
