Abstract

A control system that integrates an native control system and a non-native control system is disclosed. Data is exchanged between the two systems via a gateway interface device. Control interface objects are run on the gateway interface device to provide the exchange of data. The control interface agent configuration is based on the control connections of a native device and a non-native device.

Claims

1. A computer that is interconnected with a native control system and a non-native control system that are connected to control a process, wherein said native control system comprises a control processor interconnected with at least one native device via a native bus and wherein said non-native control system comprises first and second non-native devices connected to a non-native bus, said computer comprising:

a configuration program that provides configuration data to said control processor to configure said control processor with a control program that when run controls and monitors said process using said at least one native device and said first and second non-native devices and responds to a signal from said first non-native device to cause said second non-native device to perform an action for control of said process and that configures a control interface agent with control data flow connections of said control processor and said first and second non-native devices for control of said process, wherein said configuration program transfers said control interface agent to a gateway interface device that is connected to said non-native bus of said non-native control system and to said control processor of said native control system via a network, wherein said control processor when running said control program controls the operation of said first and second non-native devices in the control of said process via the control data flow connections of said control interface agent, wherein said control interface agent is further configured to translate a status expressed in a native language to a non-native language and vice versa, and wherein said status is provided by one of said first and second non-native devices.

2. The computer of claim 1, wherein at least one of said first and second non-native devices has more intelligence than said native device.

3. The computer of claim 1, wherein said control interface agent is one of the group consisting of:

input agent and output agent.

4. The computer of claim 1, wherein one of said control data flow connections is to said native device.

5. A method for controlling a process with a control system that comprises a computer that is interconnected with a native control system and a non-native control system that are connected to control a process, wherein said native control system comprises a control processor interconnected with a least one native device via a native bus and wherein said non-native control system comprises first and second non-native devices connected to a non-native bus, comprising:

providing said computer with a configuration program that configures said control processor with a control program that when run controls and monitors said process using said at least one native device and said first and second non-native devices and responds to a signal from said first non-native device to cause said second non-native device to perform an action for control of said process;

providing a control interface agent with control data flow connections between said control processor via a network and said first and second non-native devices via said non-native bus for control of said process; and

controlling said process with said control processor running said control program to control the operation of said first and second non-native devices via the control data low connections of said control interface agent, wherein said control interface agent is provided in a gateway interface device that interconnected with said control processor of said native control system and said non-native bus of said non-native control system, wherein said control interface agent is further configured to translate a status expressed in a native language to a non-native language and vice versa, and wherein said status is provided by one of said first non-native device, second non-native device and said process controller.

6. The method of claim 5, wherein another control interface agent is transferred in said gateway interface device to provide an additional connectivity between said control processor and said second non-native device.

7. The method of claim 6, wherein said first non-native device and said second non-native device are a sensor and an actuator, respectively.

8. The method of claim 6, wherein said control interface agent is further configured to translate a first status expressed in a non-native language into a native language, wherein said other control interface agent is further configured to translate a second status expressed in a native language into a non-native language, and wherein said first and second non-native devices provide said first and second status, respectively.

9. The method of claim 5, wherein at least one of said first and second non-native devices has more intelligence than said native device.

10. The method of claim 5, wherein said control processor processes data provided by said first non-native device and provides output control data to said second non-native device.
