I have a system that uses remote IO with redundant L72 processors communicating with a fiber loop. My question is if i loose power to the processors on return of power will the logic remain in the same state as when it lost power. I know the ECM stores the data of the program but not sure if it saves the states of tags/bits. "for example a tag that is latched will it remain latched when power is returned." I do not have an on power up program or an on fault program so from what i can tell when power returns to the processor the program will be in a fault mode and i will have to manually clear the faults but after that will all the bits be latched that were latched when the processor failed/faulted/lost power or should i make a first scan/power up logic that will latch all that need to be latched. I should probably make the first scan/ power logic anyway but as of right now i don't have one.
I appreciate it.
Thank You
