Abstract

A control studio object system is disclosed which allows a process control environment to be easily and quickly configured or modified. The control studio object system includes a stencil portion having stencil items conforming to algorithms and a diagram portion to which the stencil items may be copied via a drag and drop operation. Because the stencil items are objects which contain all of the information required by a diagram portion to create an object that contains all of the information necessary to program the process control environment, the completed diagram portion reflects the actual configuration of the process control environment. Additionally, providing the stencil items as objects allows the diagrammed environment to be installed directly to nodes without requiring the diagram to be compiled or rewritten in a language conforming to the node.

Claims

1. A method for configuring a process control environment, the process control environment including a computer system having a processor coupled to a display device, the method comprising:

presenting, on the display device, a stencil view including a stencil object, the stencil object representing a process control module;

presenting, on the display device, a diagram view, the diagram view representing the process control environment configuration;

dragging the stencil object from the stencil view to the diagram view;

dropping the stencil object on the diagram view in a position indicative of a location of the process control module in the process control environment; and

configuring the process control environment in accordance with the diagram view.

2. The method of claim 1 wherein the step of dragging the stencil object from the stencil view to the diagram view includes the step of actuating the stencil object.

3. The method of claim 2 wherein the step of actuating the stencil object includes:

presenting a cursor on the display device, the position of the cursor being controlled by a user interface device coupled to the computer system,

moving the cursor to a position over the stencil object.

4. The method of claim 3 wherein the step of dragging the stencil object from the stencil view to the diagram view further includes the step of:

moving the cursor from the stencil view to the position on the diagram view indicative of a location of the process control module in the process control environment.

5. The method of claim 1 wherein the steps are implemented using an object oriented framework.

6. The method of claim 5 wherein the object oriented framework includes classes;

and

the classes are derived from and included with a set of commercially available foundation classes.

7. A system for configuring a process control environment comprising:

a computer system having a processor coupled to a display device;

means for presenting a stencil view, the stencil view including a stencil object representing a process control module;

means for presenting a diagram view on the display device, the diagram view representing a process control environment configuration;

a user interface, operatively coupled to the display device, for controlling the dragging of the stencil object from the stencil view to the diagram view and for controlling the dropping of the stencil object on the diagram view in a position indicative of a location of the process control module in the process control environment.

8. The system of claim 7 further comprising:

means for presenting a cursor on the display device, movement of the cursor being controlled by the user interface, the user interface allowing a user to control the cursor to select the stencil object in the stencil view and to drag the stencil object from the stencil view to a position in the diagram view indicative of a location of the process control module in the process control environment.

9. The system of claim 8 wherein the means for presenting a cursor is implemented using an object oriented framework.

10. The system of claim 8 wherein the means for presenting a cursor is implemented using an object oriented framework.

11. The system of claim 7 wherein the user interface device is a mouse.

12. The system of claim 7 wherein the means for presenting a diagram view is implemented using an object oriented framework.

13. The system of claim 12 wherein the object oriented framework includes classes;

and

the means for presenting a diagram view includes classes derived from and included with a set of commercially available foundation classes.

14. The system of claim 7 wherein the means for presenting a stencil view is implemented using an object oriented framework.

15. The system of claim 10 wherein the object oriented framework includes classes;

and

the means for presenting a cursor includes classes derived from and included with a set of commercially available foundation classes.

16. The system of claim 14 wherein the object oriented framework includes classes;

and

the means for presenting a stencil view includes classes derived from and included with a set of commercially available foundation classes.

18. The system of claim 16 further comprising:

means for presenting a cursor on the display device, movement of the cursor being controlled by the user interface, the user interface allowing a user to control the cursor to select a stencil object in the stencil view and to drag the stencil object from the stencil view to a position in the diagram view indicative of a location of the process control module in the process control environment.

19. The system of claim 18 wherein the object oriented framework includes classes;

and

the means for presenting a cursor includes classes derived from and included with a set of commercially available foundation classes.

20. The system of claim 18 wherein the means for presenting a diagram view is implemented using an object oriented framework.

21. The system of claim 20 wherein the object oriented framework includes classes;

and

the means for presenting a diagram view includes classes derived from and included with a set of commercially available foundation classes.

22. The system of claim 18 wherein the means for presenting a stencil view is implemented using an object oriented framework.

23. The system of claim 22 wherein the object oriented framework includes classes;

and

the means for presenting a stencil view includes classes derived from and included with a set of commercially available foundation classes.

17. A system for generating new a process control environment comprising:

a computer system having a processor coupled to a display device;

means for presenting a stencil view, the stencil view including a plurality of stencil object representing respective process control modules;

means for presenting a diagram view on the display device, the diagram view representing a process control environment configuration when the process control environment is generated;

a user interface, operatively coupled to the display device, for controlling the dragging of one or more of the plurality of stencil objects from the stencil view to the diagram view and for controlling the dropping of the stencil objects on the diagram view in positions indicative of a location of the respective process control module in the process control environment; and

means for interconnecting the dropped stencil objects to provide the new process control environment.
