EDIT: The CPU is a PLC5 5/60, we are programming with RsLogix5
Dear PLCTalkers,
I'm currently at a customer (for a different project but i like to help and learn) and they have a broken press. The problems occurred after a power outage.
They didn't know where the problem was and took out a Analog in card (1771IFE/C) and put it back in later, when they put the card back in the Run LED kept flashing (No configuration loaded), so i checked the program and the BTW is enabled but i don't receive the Error nor the Done bit.
Note: The problem was a broken component and they switched the fuse, AFTER they took out the analog card. So now the component is working but the analog card is giving issues.
So we took a spare card, still same problem. Took another spare card, still same problem :/
I guess we can rule out the card is the problem.
So i suspect the backplane is damaged/corroded and when they took out the card and put it back in they might have pushed some corrosion in the connectors and because of that the card has no proper connection?
I have read countless documentations but i can't find anything on what the problem might be if you don't receive a Done or a Error bit on a BTW/BTR.
Does someone have any pointers?
Thanks alot!

UPDATE:
They took out another Analog in card and after putting it back in, that card also starting flashing green (no configuration loaded). We now have the same communication issue.
