PROBLEM TO BE SOLVED: To facilitate specifying an irregularity occurrence portion in a monitoring control system.SOLUTION: A monitoring control system comprises: a CPU 1 that is connected to a radio receiver; a driver 2 that controls a plurality of site devices on the basis of a control signal to be transmitted from the CPU; a relay unit 3 that delivers data to be transmitted from the driver to a plurality of relay devices with the data distributed to the plurality of relay devices; an IO 5 that has a self-diagnostic program including a plurality of processes; and a radio transmitter 82 that is connected to the IO. The IO is configured to: when the self-diagnostic program is started up and one process is ended, check out whether the process is normally implemented; when irregularity is found out in the process, light on an LED; when the process is normally implemented, transit to next process; and transmit a check-out result to the radio transmitter. When receiving the check-out result from the radio transmitter, the radio receiver is configured to transfer the received check-out result to the CPU.SELECTED DRAWING: Figure 1 |
