Abstract
A time division multiplex remote control system controls data transmission between a central controller and a plurality of addressable remote terminals coupled to the central controller through a signal line. The central controller transmits to each of terminals a transmission signal comprising address data addressing a terminal, control data, a reply signal standing-by period defining signal for defining a period for receiving a reply signal from the corresponding terminal, an interruption request signal standing-by period defining signal for defining a period for receiving an interruption request signal from the terminal. Each terminal receives the transmission signal and, when the received address data coincides with an address of the terminal, accepts the control data and sends a reply signal during a reply signal standing-by period. Each terminal further detects a change of a supervisory input which the terminal supervises and sends an interruption request signal at the timing of the interruption request signal standing-by period of the transmission signal.
