Allen Bradley 5000 different versions of software

[pierceluke]

I use Allen Bradley 5000 PLCs, I have 5 of them communicating with each other. Three of them run on version 17.01.00, one on version 19.01.00, and one on version 20.03.00. I am having problems with motors energizing directly after power failure even when they weren't on before the power failed. I am wondering if these different versions of software could have something to do with the abnormal occurrences happening.

I appreciate the help!

Not likely (never seen a report about it) but examining the logic that turns them on may be of value to better answer your questions.
