Nec Magnus Communications Ltd. and NEC Corp | Date: 2011-08-04

A controlled apparatus periodically transmits state information indicating the state of the apparatus, and when the state has been changed, transmits state information indicating the state after the change. Upon receiving state information from the controlled apparatus, a control apparatus, when not requesting a change of state in the controlled apparatus, returns the state information to the controlled apparatus, and when requesting a change of the state in the controlled apparatus, changes state parameters in the state information that correspond to the state to be changed to required values and transmits the state information after the change to the controlled apparatus as a control command. The controlled apparatus, upon receiving the control command from the control apparatus, changes to a state in accordance with the state parameters that follow the change and transmits the state information indicating the state after the change to the control apparatus.

A center device performing power feed control generates a control signal for controlling supply and suspension of power to a main load of a remote terminal and transmits the control signal by superimposing the control signal on the power to be supplied to the remote terminal. The remote terminal includes a power-receiving side unit, a switch that connects the power-receiving side unit with the main load when the switch is on and disconnects the power-receiving side unit from the main load when the switch is off, and a control signal receiver that receives the control signal superimposed on the power transmitted from the center device to turns the switch on or off in accordance with the control signal received at the control signal receiver.
