At the periodic interval, the CPU sends diagnosis data to the Port Microprocessor (PM) on LC/TRK cards in order to monitor the PM. If the CPU cannot receive the return data within a predetermined period of time, the system displays this data. When the failure is detected more than 15 times per hour, the failure is judged as permanent.
