テム。The main operation panel and multiple terminal devices are connected to each other via a pair of signal lines, and the main operation panel waits for an address signal consisting of multiple bits and a control data signal consisting of multiple bits to be returned to each terminal device. A signal in which long pulse signals are arranged in series is cyclically transmitted for each address. The control output means that generates a control output according to the control data signal and the signal line are short-circuited through an appropriate impedance during the period of the long pulse signal for waiting for the return, so that the monitoring signal consisting of a plurality of bits can be output as a return current. In a remote monitoring and control system that is equipped with a monitoring signal return means that sends back a monitoring signal to the main operation panel side, a group of input switches for connecting a sub-operation panel containing a number of terminal devices each having a different address to the signal line and inputting address signals and control data signals of arbitrary terminal devices into the sub-operation panel; A means for distributing and inputting the data inputted by the input switch group to each monitoring signal return means of a plurality of terminal devices in the sub-operation panel is provided, and address signals and control signals returned from the sub-operation panel to the main operation panel are provided. A remote monitoring control system that transmits data signals from the main operation panel to each terminal.
