Hi every, I have two PLCs both 1756-L55 processors, when I open each of their respective programs in RSLogix 5000, in one I can see the backplane, processor, etc, but the other one looks like this:
I want to be able to communicate between the two PLCs but I can't as either using messages or producing consuming bits instructions state you should have the other PLC added to the I/O configuration of the PLC it's talking to. I can't access the Ethernet part of the I/O configuration like I can in the example below so I can't add the other PLC.
I really can't see what's going on, I tried adding the processor which is in slot 0, but then I get a message saying this slot is already in use, at the moment both PLCs do operate but don't talk to each other
