Abstract

The present invention provides techniques for automatically binding device parameters to an input and output interface. Doing so enables dynamic parameters to be available to the core firmware engine. More specifically, there is no input and output data in the configuration software domain required for mapping the parameters. Rather, the configuration software may directly access the device parameters during the logic execution. This is achieved in a library by representing the parameter repository and the EPATH pointing to each parameter from the configuration software domain.

Claims

1. A method for distributed control of a process, comprising:

accessing a function block configured to perform an arithmetic or logical operation on a parameter having a first parameter designation; and

configuring an automation control device that forms part of a machine or process control system, the automation control device storing the function block and executing the function block in operation in the machine or process control system, wherein configuring the automation control device comprises storing in the automation control device a conversion of the first parameter designation to a second parameter designation utilized for the same parameter in the machine or process control system.

2. The method of claim 1, wherein storing the conversion comprises storing in the automation control device a mapping of the first parameter designation with the second parameter designation.

3. The method of claim 1, comprising accessing a mapping of parameters utilized in a machine or process control system, and configuring the automation control device based upon the mapping.

4. The method of claim 3, wherein the mapping is accessed from an electronic data sheet file for the machine or process control system.

5. The method of claim 3, wherein the mapping is accessed from the automation control device.

6. The method of claim 1, wherein the function block is accessed from the automation control device.

7. The method of claim 1, wherein the function block is accessed from a library of function blocks available for use in the automation control device.

8. The method of claim 1, wherein the arithmetic or logical operation comprises reading the parameter from a memory circuit external to the automation control device.

9. The method of claim 1, wherein the arithmetic or logical operation comprises writing the parameter to a memory circuit external to the automation control device.

10. The method of claim 1, wherein the first and second parameter designations correspond to parameter names utilized by different industrial data communications protocols.

11. The method of claim 1, wherein the function block comprises non-transitory code configured in an object oriented programming language.

12. The method of claim 1, wherein the automation control device comprises an input/output terminal block.

13. The method of claim 1, wherein the automation control device comprises a push-button block.

14. The method of claim 1, wherein the automation control device comprises an overload relay.

15. The method of claim 1, wherein the automation control device comprises a motor drive or motor starter.

16. A distributed automation control device, comprising:

a memory circuit storing a function block configured to perform an arithmetic or logical operation on a parameter having a first parameter designation; and

a processor configured to execute the function block in operation in the machine or process control system;

wherein the memory circuit stores a conversion of the first parameter designation to a second parameter designation utilized for the same parameter in the machine or process control system.

17. The device of claim 16, wherein the memory circuit stores a mapping of the first parameter designation with the second parameter designation.

18. The device of claim 16, wherein the distributed automation control device comprises an input/output terminal block.

19. The device of claim 16, wherein the distributed automation control device comprises a push-button block.

20. The device of claim 16, wherein the distributed automation control device comprises an overload relay.

21. The device of claim 16, wherein the distributed automation control device comprises a motor drive or motor starter.

22. A distributed control system, comprising:

a distributed automation control device, comprising a memory circuit storing a function block configured to perform an arithmetic or logical operation on a parameter having a first parameter designation, and a processor configured to execute the function block in operation in the machine or process control system, wherein the memory circuit stores a conversion of the first parameter designation to a second parameter designation utilized for the same parameter in the machine or process control system; and

an automation controller coupled to the distributed automation control device via a network;

wherein the distributed automation control device is configured to communicate with the automation controller via the network, but executes the function block utilizing the second parameter designation without command from the automation controller.

23. The system of claim 22, wherein the distributed automation control device comprises an input/output terminal block.

24. The system of claim 22, wherein the distributed automation control device comprises a push-button block.

25. The system of claim 22, wherein the distributed automation control device comprises an overload relay.
