Another tosser with zero credibility. On the basis of this reported instance completely lacking useful details about the actual cause of the power outages, the actual sequence of events or information about a whole host of factors that may have caused these issues, you leap to a totally unsupported generalised conclusion about AB PLC's. And despite it being such a patently daft thing to say, you didn't have the self-restraint to think about how ill-informed it was going to make you look before posting it.
Or are you telling us that there has NEVER been an instance of any Seimens PLC hardware EVER failing for any reason whatsoever...anywhere in the world, anytime over the last 30 years? Are you telling us that Seimens PLCs are SO reliable that they NEVER fail?
Now just to satisfy my curiosity I have just gone off to one of my CLX systems ( a reasonably large one) that happens to be offline at the moment and I've flicked the power to it on and off about a 40 times in ten minutes, some of them of them as quickly as possible. Not the slightest hint of problems. You've got me worried...according to your comments I should be looking at a smouldering wreckage of crispy AB PLC drooping off the back of my cabinets.
