<p>PROBLEM TO BE SOLVED: To surely prevent the generation of the inspection omission of the normal operation of a load by the operation of a switch connected to a multiplex communication system. SOLUTION: While control data is being transmitted and received, via a multiple bus line L, by communication means 11B between a plurality of units 1 to 7 in which switches 13 and loads 14 operated according to the operation of the switches are connected, at least one out of outputs of signals to the loads 14 corresponding to inputs of signals from the switches 13 is controlled by control means 11A. At this time, a storage means 11bA is installed at the unit 1, and control data which is transmitted and received between the respective units 1 to 7 is constituted so as to be stored in the storage means 11bA by a control data collection means 11C. The switches 13 which have been operated in an inspection are deduced from the storage content of the storafe means 11bA, the unoperated switches 13 out of the switches 13 to be operated for the operation of the loads 14 as objects to be inspected or the uninspected loads 14 corresponding to the switches are deduced.</p> |
