A main control circuit unit 20A and a monitoring control circuit unit 30A are connected in series; the main control circuit unit 20A and an external control apparatus 40 are connected in series. When the monitoring control circuit unit 30A generates concurrent question information, the main control circuit unit 20A generates main-machine answer information A1n, and the external control apparatus 40 generates supplementary-apparatus answer information. The main control circuit unit 20A combines these answer information items and transmits the combined answer information items to the monitoring control circuit unit 30A; the monitoring control circuit unit 30A compares the combined answer information items with synthesis correct-solution information items stored in a correct-solution information storage memory 35A so as to perform a total abnormality determination. The main control circuit unit 20A performs an abnormality determination on the external control apparatus 40, based on correct-solution information for the external control apparatus 40; the main control circuit unit 20A generates synthesis answer information by use of the correct-solution information. |
