ない。As described above, according to the present embodiment, the load status notification communication device 9 having the ON / OFF status detection means 13 of the connected load 16 is provided with the address setting means 11 for the own station address and the storage means 12 for the address. When a change in address setting is recognized, the value stored in the storage unit 12 is set as the own station address, and the own station address is set as the address setting unit 1.
It is possible to match the current load state with the display unit 14 of the display communication device 10 by transmitting the fact that the value has been changed to 1 and the current state notification. Although the load status notification communication device 9 reports the status when the load status changes in the embodiment, the status notification may be performed at all times. It goes without saying that a communication system based on polling may be used.
