Communication network system
First Claim
1. A communication network system in which a communication network of a system, including a system controller and a plurality of first controlled devices, and a different communication network of a master system, including a master controller and a plurality of second controlled devices, are unified to form a unified communication network,wherein each of the plurality of first controlled devices is configured to transmit status information of the first controlled device to the master controller, and receive control information of the first controlled device from the master controller, so that the first controlled device is operated based on the received control information,wherein the master controller comprises a control unit which is configured to receive status information of the plurality of first controlled devices and transmit control information to the plurality of first controlled devices, the control unit being configured to transmit the status information of the plurality of first controlled devices to the system controller and receive the control information of the plurality of first controlled devices from the system controller, and the control unit being configured to transmit control information of the system controller to the system controller and receive system status information of the system controller from the system controller,wherein the system controller comprises a second control unit which is configured to receive the status information of the plurality of first controlled devices from the master controller, perform a processing operation based on the received status information, and transmit a result of the processing operation to the master controller as the control information of the plurality of first controlled devices, the second control unit being configured to transmit the system status information of the system controller to the master controller, and receive the control information of the system controller from the master controller, so that the system controller is operated based on the received control information.

Abstract
In a communication network system which unifies a system communication network and a master system communication network, each of a plurality of controlled devices is configured to transmit status data to a master controller and receive control data from the master controller so that the controlled device is operated based on the control data. The master controller comprises a control unit configured to receive status data of the controlled devices and transmit control data to the controlled devices, the control unit being configured to transmit the status data to a system controller and receive the control data from the system controller. The system controller comprises a second control unit configured to receive the status data of the controlled devices from the master controller, perform a processing operation based on the status data, and transmit a result of the processing operation to the master controller as the control data.
