As shown in the eighth factor, the central ♂II control device 1, the monitoring terminal device 2 that monitors the operation inputs from the operation switches sw, , sw2, etc., and the load, L2...
A control terminal device 3 that controls ti is connected to a pair of signal lines t, and each monitoring terminal device 2 is accessed from the central control device 1 to send back monitoring data, and data is formed based on the monitoring data. The control data for controlling the load, L2, . FIG. 9 shows an example of the transmission signal V9 transmitted from the central control device 1. The transmission signal Vs transmitted as a bipolar signal includes a start signal ST indicating the start of signal transmission and a transmission signal V9 transmitted from each terminal device 2. .3, a control data signal CD that transmits control data to the control terminal 3, and a return waiting period signal WT. Each data is a pulse. It is transmitted using width modulation. In addition, a return signal VB for returning monitoring data or a control confirmation signal from each monitoring terminal device 2 or control terminal device 3 to the central control device 1 is used as a current mode signal (as appropriate between the signals AaA and signal obtained by connecting a low resistance). Further, each terminal device 2, 3 rectifies and smoothes the transmission signal Vs to obtain circuit power.
