Modicon PLC Stops Running

[Guest Mr. Burg]

Currently working with a Modicon Momentum PLC (M1 960-30) & ProWorx 32 software. PLC runs OK in every respect: code, online changes, saving, communication on TCP/IP to Lpt & PanelMate. Every now & then the controller will be stopped, when I haven't clicked stop controller before going offline & closing ProWorx 32. Why / what would stop the controller? I know when you cycle power the controller should boot up & begin running. I have already transfered the program to EEPROM, anyone know why the controller would stop on its own? Thanx in advance...

There should be a stop code stored in the PLC's memory that you could read in Proworx to determine the reason it's stopped. Look at the PLC diagnostics in Proworx.
