Abstract

A networked control system includes graphical representations of actual devices coupled to a network. The graphical representations include symbols that provide an actual picture of the devices and means for displaying values and status of the devices. A controller uses a system database to create an application database that is used for controlling and monitoring the devices. The system database includes templates for the physical devices with a control structure that has prelinked parameters that relate to the representation. A graphic editor allows a user to create the database from templates in the system database. Data and other device parameters are automatically linked to a device symbol when creating the graphical representations. A process controller couples the devices to the network and provides the data and status of the networked device to the system database.

Claims

1. A control structure comprising a controller, a plurality of physical devices coupled to the controller, wherein the controller is adapted to control and monitor the physical devices, and a user interface coupled to the controller for displaying representations of status conditions of the physical device, the control structure comprising:

a system database adapted to include the representations of the physical device;

means for creating the system database within the user interface;

means for representing each of said plurality of physical devices within the control structure for use within the user interface, the representing means adapted to be accessible from the system database, the system database having groupings of the representing means that are grouped according the location of the physical device which the representing means represents, the groupings being arranged in a distributed database configuration for real-time use; and

means for viewing and controlling said representing means of each of said plurality of physical devices from said user interface.

2. The user interface claimed in claim 1 wherein the representing means comprises points, pointgroups, graphical symbols, and logical parameters.

3. A monitoring and control system comprising:

A. a system network;

B. a memory accessible from said system network;

C. at least one process control unit for coupling a network of single and multiple parameter devices to said system network, said process control unit for generating values and status for each of said devices;

D. a system data base stored in said memory, said data base including graphical symbols for said networked devices; and

E. at least one controller coupled to said system network, said controller including a memory for storing an application database and a processor for using said system data base to create graphical representations of each of said networked devices in said application data base, and for monitoring and controlling said networked devices in response to said graphical representation, said graphical representations including values and status of said networked devices.

4. The monitoring and control system of claim 3 wherein said system data base further includes points and pointgroups adaptable to represent said values and status of said networked devices, said points including a point name to represent said single parameter devices and said pointgroups having a pointgroup name to represent multiple parameter devices.

5. The monitoring and control system of claim 4 wherein each of said pointgroups includes a point for each physical parameter of said multiple parameter device.

6. The monitoring and control system of claim 5 wherein said graphic symbols for said networked devices include a symbol name and logical parameters for representing status of said devices, and wherein said graphical representations include said points and symbols to represent each of said single parameter devices and said pointgroups and symbols to represent multiple parameter devices.

7. The monitoring and control system of claim 6 wherein said points representing said physical parameters of said multiparameter devices are automatically linked to said logical parameters of said symbols when a pointgroup name is linked to a symbol name when creating said application data base.

8. The monitoring and control system of claim 7 wherein said system database includes templates for said points and pointgroups, said templates including default values for said points, and wherein said controller further includes a graphic editor for creating said graphical representations for networked devices controlled and monitored by said controller from said templates, said graphical representations stored in graphical display files in said application database for use by said processor for controlling and monitoring said networked devices.

9. The monitoring and control system of claim 8 wherein said controller further includes a graphic viewer for viewing said graphical representations of said networked devices controlled and monitored by said controller, said graphic viewer including means for selecting a graphical representation of a networked device from said graphic display file, means for viewing values and status of said networked device, and means for updating said graphical representation in said graphic display file with real time values and status of said networked device generated by said process control unit.

10. A system for controlling and monitoring physical devices coupled to a network comprising:

A. a memory accessible from said network;

B. a plurality of process control units, each of said plurality of process control units for coupling a separate network of physical devices to said network, said process control unit for generating values and status for each of said networked physical devices;

C. a system data base stored in said memory, said data base including graphical symbols of said physical devices;

D. at least one controller coupled to said system network, said controller including a processor for using said system data base to create an application data base including graphical representations for each of said networked devices, said graphical representations including said graphical symbol and points for use in displaying said values and status of said networked physical devices, said controller for monitoring and controlling said networked devices in response to said graphical representations; and

E. a graphic editor included in said controller for creating said graphical representations for said networked devices controlled and monitored by said controller, said graphical representations stored in graphical display files in said application database for use by said processor for controlling and monitoring said networked devices.

11. The monitoring and control system of claim 10 wherein said system data base further includes points and pointgroups adaptable to represent said values and status of said networked physical devices, said points including a point name to represent single parameter devices and said pointgroups having a pointgroup name to represent multiple parameter devices.

12. The monitoring and control system of claim 11 wherein each of said pointgroups includes a point for each physical parameter of said multiple parameter device.

13. The monitoring and control system of claim 12 wherein said graphic symbols for said networked physical devices include a symbol name and logical parameters for representing status of said devices, and wherein said graphical representations include said points and symbols to represent said single parameter devices and said pointgroups and symbols to represent multiple parameter devices.

14. The monitoring and control system of claim 13 wherein said points representing said physical parameters of said multiparameter devices are automatically linked to said logical parameters of said symbols when a pointgroup name is linked to a symbol name.

15. The monitoring and control system of claim 14 wherein said system database includes templates for said points and pointgroups, said templates including default values for said points, and wherein said graphic editor creates said graphical representations for networked physical devices controlled and monitored by said controller from said templates.

16. The monitoring and control system of claim 15 wherein said controller further includes a graphic viewer for viewing said graphical representations of said networked physical devices controlled and monitored by said controller, said graphic viewer including means for selecting a graphical representation of a networked device from said graphic display file, means for viewing values and status of said networked device, and means for updating said graphical representation in said graphic display file with real time values and status of said networked device generated by said process control unit.
