PURPOSE: To conduct the simplification of processing and the reduction of processing time by limiting control information to be generated only to one kind of control code when plural device groups to be controlled are controlled by one controller.
CONSTITUTION: The controller (a) inputs a control origin signal from a control origin signal input part 6, and generates the control information at a control information generating part C based on the control origin signal. At this time, the controller (a) generates only one kind of control code, and attaches the addresses of the devices h 1-hn to be controlled at an address attaching part (e), and transmits them to the device group (g) to be controlled as the control information. The devices h 1-hn to be controlled judge the feasibility of the control information to be received from the controller (a) by an address detecting part 1, and receive the information by a control information receiving part (j) when it is feasible, and a control information analysis part (m) analyzes a control content expected by the controller (a) from the control code in received control information, and a control execution part K executes the control of the devices h 1-hn to be controlled.
