Abstract

A uniform resource locator (URL) is embedded in computerized or digital documentation for a physical and/or a software process control element existing within a process control environment to thereby provide an automatic link to documentation or other applications that exist in other processing or data environments, such as in a word processing environment or in a data manipulation environment. The URL may include a generalized field having a descriptor that identifies a property of the process control element and that operates so that, when the URL is selected, the generalized field is replaced with the property identified by the descriptor.

Claims

1. A computer readable memory storing a process control application for implementation and use in a control programming environment associated with a process control system having a multiplicity of process control elements therein, the process control application when executed by a controller provides the following:

a display having a plurality of display fields for one of the multiplicity of process control elements, each of said display fields including information displayed to a user and adapted to be stored in a memory within the process control system; and

a context sensitive uniform resource locator disposed in one of the display fields of the display screen to point to an address of an external entity, the address to which the context sensitive uniform resource locator points dynamically changing in response to changes to an attribute value of the one of the multiplicity of process control elements.

2. The computer readable memory of claim 1, wherein the uniform resource locator includes a distinctive characteristic that distinguishes the uniform resource locator as a uniform resource locator when displayed.

3. The computer readable memory of claim 2, wherein the distinctive characteristic is underlining.

4. The computer readable memory of claim 2, wherein the distinctive characteristic is a particular color.

5. The computer readable memory of claim 1, wherein the uniform resource locator identifies an entity in a second programming environment that is a different programming environment than the control programming environment.

6. The computer readable memory of claim 5, wherein the second programming environment is a word processing environment.

7. The computer readable memory of claim 5, wherein the second programming environment is a World Wide Web environment.

8. The computer readable memory of claim 5, wherein the second programming environment is a local area network environment coupled to the process control system.

9. The computer readable memory of claim 1, wherein the one of the multiplicity of process control elements is a software element capable of being implemented on a processor within the process control system.

10. The computer readable memory of claim 9, wherein the one of the multiplicity of process control elements includes a function block.

11. The computer readable memory of claim 1, wherein the one of the multiplicity of process control elements is a physical device capable of being used within the process control system.

12. The computer readable memory of claim 1, wherein the uniform resource locator includes a generalized field that has a descriptor identifying a property of the one of the multiplicity of process control elements, and further including a routine that replaces the generalized field with the identified property of the one of the multiplicity of the process control elements to create a new uniform resource locator when the uniform resource locator is selected by a user.

13. The computer readable memory of claim 12, wherein the property of the one of the multiplicity of process control elements is the name of the one of the multiplicity of process control elements.

14. The computer readable memory of claim 12, wherein the property of the one of the multiplicity of process control elements is a location indication associated with a manner in which the one of the multiplicity of process control elements is located within the process control system.

15. The computer readable memory of claim 1, further including a browser that uses the uniform resource locator to locate and launch an entity in a second programming environment that is a different programming environment than the control programming environment.

16. The computer readable memory of claim 1, wherein the external entity is a text file.

17. The computer readable memory of claim 1, wherein the external entity is a program adapted to be executed on a processor.

18. The computer readable memory of claim 17, wherein the process control application is located in a first computer and the external entity is located in a second computer different than the first computer.

19. A computer readable memory storing a process control element adapted for implementation and use in a control programming environment associated with a process control system, the process control element when executed by a controller providing:

a process function operator;

a display having a plurality of display fields for the process function operator, each of said display fields including information displayed to a user and adapted to be stored in a memory within the process control system; and

a context sensitive uniform resource locator disposed in one of the display fields of the display screen to point to an address of an external entity, the address to which the context sensitive uniform resource locator points dynamically changing in response to changes to an attribute value of the process function operator.

20. The computer readable memory of claim 19, wherein the uniform resource locator includes a plurality of distinctive characteristics which distinguish the uniform resource locator as a uniform resource locator.

21. The computer readable memory of claim 19, wherein the uniform resource locator identifies an entity in a second programming environment that is a different programming environment than the control programming environment.

22. The computer readable memory of claim 19, wherein the process function operator is a process control device.

23. The computer readable memory of claim 19, wherein the process function operator is a software element capable of being implemented on a processor within the process control system.

24. The computer readable memory of claim 19, wherein the uniform resource locator includes a generalized field that has descriptor identifying a property of the process function operator, which property of the process function operator replaces the generalized field of the uniform resource locator when the uniform resource locator is used.

25. The computer readable memory of claim 19, wherein the external entity is a text file.

26. The computer readable memory of claim 19, wherein the external entity is a program adapted to be executed on a processor.

27. The computer readable memory of claim 26, wherein the process control element is located in a first computer and the external entity is located in a second computer different than the first computer.
