PURPOSE:To aim at simplifying the entire structure of an integrated wiring system by changing control table address data during monitoring of a main station in order to carry out multiple data transmission among lamps, switches and the like, so as to make it possible to set the cycle period and cycle number of the monitoring. CONSTITUTION:A microcomputer 180 in a central control device are commonly connected with signal transmissions LSI (CIM) of terminal processing units disposed in equipments such as switches, meters, lamps or the like by use of an optical fiber cables. In accordance with input data obtained by monitoring of CIMs in substations, the microcomputer 180 in the main station carries out computation and delivers control instructions to the substations. In this phase, address data of a reference control table (SCNTBL) is changed so as to make it possible to independently set the cycle period and cycle number of monitoring for every substation. By this simple arrangement, it is possible to preponderantly monitor real time controlling substations such as that for controlling the ignition of an engine.
