An apparatus for setting an ID number in a station of a communication system in which a multiplexed signal including a preliminary signal and a control information signal comprising the ID number is interchanged between the adjacent stations of stations connected in series, and the stations are respectively responsive to the control information signal having the same ID number as that set in the station, for controlling the station. The apparatus provides a centralized supervisor and in the station, an ID setting circuit and a switching circuit. The centralized supervisor sends to one of the stations, a control information signal including the ID number and an ID set command. The ID setting circuit sets the ID number by storing the ID number included in the received control information signal in a memory device. The switching circuit transfers the received control information signal to the succeeding first station by switching on a path along which the control information signal is carried after the ID number has been set.
