Abstract
A diagnostic and service logic program for a programmable logic controller (PLC) is provided in parallel with the main machine logic program. The diagnostic and service logic program has the same functionality as the main machine logic program, but can be modified and operated independently of the main machine logic program for testing and debugging a faulty main machine logic program. The PLC can be switched between programs for testing and debugging.
