PROBLEM TO BE SOLVED: To provide an equipment duplicating system which simplifies a control unit and a wire communication circuit while holding equipment duplication, and can ensure matching property of terminals on the side of equipment to be controlled which are generated by simplification. SOLUTION: Transmission switches 21-1 to 21-n are installed between wire communication circuits 40-1 to 40-n and communication functions 22-1A to 22-nA, 22-1B to 22-nB in equipments to be controlled 20-1 to 20-n. By switching the transmission switches 21-1 to 21-n with control functions 23-1 to 23-n, communication functions 12-1 to 12-n on a control equipment 10 side and the wire communication circuits 40-1 to 40-n are simplified.
