Hello Guys,
Question: what are common fault checks and timeouts that you program into your machinery for different components? Does anyone have a list or something they might be willing to share, for components such as pneumatic cylinders not extending/retracting in a certain amount of time, motor contactors not switching, circuit breakers tripping, etc? I was told that it is the PLC programmer's job to consider all of the possible fault scenarios, and a former coworker told me he once programmed a part of an assembly line with over 1800 faults, as somewhat of a newbie I'm wondering if there are standard faults for component/sensor combinations that are very routine. I can't imagine myself sitting there and coming up 1800 possible faults. Any answers would be appreciated.
Thanks!
