System controller for controlling a control network having an open communication protocol via proprietary communication
First Claim
1. A control network comprising a system controller and a plurality of device controllers that communicate through the network via a network specific communication protocol for controlling a plurality of network devices, said system control network comprising:
- an application controller, provided in said system controller, connected to the network for selectively converting a plurality of system points corresponding to a plurality of system variables relating to the network into said corresponding system variables, and said corresponding system variables into said system points; and
,at least one client connected to the network and in communication with said application controller, said client selectively sending a command and requesting a report relating to a select system point;
wherein said application controller sends a command relating to a system variable corresponding to said select system point to the network responsive to said command from said client, and receives a report relating to said system variable corresponding to said select system point from the network, converts said received report to said report relating to said select system point and sends said converted report to said client responsive to said report request from said client;
said communication between said at least one client and said application controller is via a system variable proprietary protocol of said system controller embedded in the communication protocol of the network, and wherein one or more of said device controllers have a server incorporated therein, said server from said one or more device controllers communicates with said application controller using a system point proprietary protocol also embedded in the communication protocol of the network.

Abstract
A system controller is adapted to be integrated into a control network including a plurality of device controllers that communicate through the network via a network specific communication protocol for controlling a plurality of network devices. The system controller includes an application controller which is adapted to be connected to the network and stores a plurality of system points corresponding to a plurality of system variables relating to the network devices. The application controller is adapted to convert the system points into the corresponding system variables, and the corresponding system variables into the system points. At least one client is connected to the network and in communication with the application controller. The client is adapted to send a command and request a report relating to a select system point to and from the application controller. In operation, the application controller sends a command relating to a system variable corresponding to the select system point to the network responsive to the command from the client. The application controller also receives a report relating to the system variable corresponding to the select system point from the network, converts the received report to the report relating to the select system point and sends the converted report to the client responsive to the report request from the client.

19. A method of isolating control applications of a system controller integrated with a network employing a network specific communication protocol for communicating between a plurality of device controllers for controlling a plurality of network devices in a system, said method comprising the steps of:
-
establishing communication between at least one client for performing the control applications and an application controller, provided in said system controller, via a system variable proprietary protocol said first proprietary protocol embedded in the network specific communication protocol, operatively establishing a connection between said application controller and the network; storing a plurality of system points which correspond to a plurality of system variables relating to the network devices in a memory operatively connected to said application controller; obtaining data relating to a system variable on the network corresponding to a select system point requested by said at least one client, and converting said data relating to said select system variable to data relating to said select system point responsive to said request from said client; and
, providing said client access to said converted data;incorporating a server in one or more of said device controllers and using a system point proprietary protocol embedded in the network specific communication protocol to communicate between said application controller and said server in said one or more said device controllers. - View Dependent Claims (20, 21)
