I had bought a used PLC before but I had to return it. Once in a while its run mode shut off momentarily. I had the PLC on my desk. (No I/Os wired) At one point I saw that happening. No issue with the power supplying the PLC. If I was running a machine with it, it would have taken a while before I realized that was going on.
Now I am again buying a used PLC, Micrologix1000 1761-L32AWA. I am going to download a program (No I/Os wired) and then leave it in the run mode for several days.
Is there a way to write a program so I know if it loses the Run Mode? Of course, assuming no issue with the power supplying the PLC.
