We had a CP1E go bad (power issue). Installed spare and could not get it to communicate to our motion drive via add on RS485 card. Tried everything I could with no luck. We pulled the exact same model PLC from an idle machine and installed it, worked like a charm.
Figured our spare PLC was bad, bought a new one. New one is having the exact same communication issue as our spare on the idle machine that was working fine before we borrowed the PLC. I have tried clearing PLC memory, uploaded programs from working machines, etc, no luck.
Any ideas? To me, it seems we are not initializing something correctly when installing a brand new PLC.
