Hi, im having an issue with programming on a 1756-L72 ControlLogix 5570 where every time I update a tag value it will save for that day, then the next day when I come in the tag value has gone back to its previous state. I am backing up the program in Asset Centre and the archived version matches the changes I make but the PLC is losing the changes daily. We have been using this system for our 2d label scanners for years and this issue started happening just a few months ago. Anyone have any experience with a similar issue?
