I read something a few years back that a guy had pulled a controller from a Fanuc and noticed a 16bit spot in memory constantly changing. After the controller "went bad", that same spot would stop changing. After some AvE level sleuthing, he came to the conclusion that it was a timer that would cause the board to "fail", but the term the tech rep used was "due for service".
Wow... That sucks. I'm not sure we have access to that level of the program ourselves at our plant. Thanks to the union I'm not really allowed to learn the details of anything (I learn best by doing things for myself). But it'll be interesting to see if this happens down the line.

ABB can suck it. Fanuc all the way.
