I have a 1769 Compactlogix here with 2 analog cards in it. My problem is when there is a power loss or cycle of power the system starts fine but the processor does not communicate with the cards. The values are stuck in last state. In order to get the cards talking again I have to inhibit the cards or switch the processor from Run to program and back to run, then everything is fine again. Is this a firmware problem? i am running version 15 and everything is in one chassis. Any help would be appreciated.
