Two second devices, first and second bus control means for enabling control by each control bus, and command system conversion means for mutually converting commands according to the command system of each control bus A target command expansion means for receiving a status change notification indicating a status change of the first device or a final purpose command representing a final purpose of control started by using the status change as an activation factor and expanding the final command into a target command representing the purpose of control.
Centralized device storage means for storing the second device which is the destination of the target command and centrally manages the system configuration information on the control bus is provided, and the target command indicating the purpose of control is transmitted to the second device. It consists of a gateway device.

[0028]

According to the present invention, with the above-described structure, when a state change occurs in a device connected to one control bus, the state change notification transmitted by the state change transmission means of this device or the final purpose command transmission means. The gateway device receives, by the first bus control means, the final purpose command indicating the final purpose of control that starts with the state change transmitted by the first bus control means.

The target command expansion means of the gateway device expands the received status change notification or final purpose command into a target command representing a more detailed control purpose, and the command system conversion means expands the expanded target command of the other control bus. After converting into a command system, the second bus control means transmits the above-mentioned target command to a device that centrally manages the system configuration information stored in the centralized management device storage means.

The device which receives the above-mentioned target command concretely executes the target command by the target command executing means according to the system configuration information held by the system configuration information holding means for centrally managing the system configuration information.
