I would like to make a small discussion about ways of reading out serial number of PLC Rack in RSLogix.
I know only about one way of doing it. There is message instruction with BackplaneRead option where you can get several information out of backplane. What concerns me now is I have like 50 PLCs running in production and want to get this information without influencing code itself and create MSG instruction.
Does anyone know what are other possibilities ?
I will really appreciate every other solution.
Cheers!
