PURPOSE:To shorten control time and to eliminate the limit of the number of subordinate equipments, by allowing the subordinate equipments to perform load control immediately by a signal from a control part, and also to transmit load states. CONSTITUTION:A master equipment B sends a transmitted signal containing a load control signal to a signal line A. A subordinate equipment C receives the transmitted signal from the master equipment B to control a load D by a load control signal which corresponds to its own address. For the subordinate equipment C, a different address is set and a necessary number of addresses are provided to the signal line A. A control part E supplies a signal for controlling the load D to the subordinate equipment C. Then, the equipment C controls the load D by the signal from the control part E without the intervention of the master equipment B, and transmits the control state of the load D to the master equipment B through the signal line A. |
