In the program, high-level instructions, which execute in every
scan and at the leading edge of the trigger, are programmed to
be triggered by one contact. Correct the program so that the
high-level instructions executed in every scan and only at the
leading edge are triggered separately.

power supply is cut off, or when the unit is set to the RUN mode again after the status has been
