Hi everyone, first time posting here.
I have a problem with 1747-SDN devicenet scanner, connected to 3 Numatics G2-2 valve modules. We had a fault where node 1 would turn on all solenoids when the output power was applied, so we tried swapping a few parts around to see if we could pin down the fault. No success so we put everything back and ordered a new comms module for node 1. We had an original .dnt file and EDS file for the network so we downloaded that again and now we have error 77 on nodes 1 and 2. The comms modules for these nodes have newer firmware than original (looks like node 2 has been replaced some time in the past), could it be that I need a newer EDS file for the newer comms modules as the I/O's shouldn't have changed?
