I have a micrologix 1200 in one of my machines, it's about 2 years old now, recently one of the outputs shows voltage (+24vdc) at all times, even when the output is not true.
I can cycle the run button on and off, and see the output light go on and off, but when I measure voltage at that output terminal, there is +24 there at all times, it does not switch off.
I am suspecting the PLC has internal short or something of that nature, and have ordered a new one.
Any thoughts?
