Abstract

An industrial automation device comprises a data storage component that retains at least a portion of a schema, the schema facilitates usage of a hierarchically structured data model by the industrial automation device. A processor is communicatively coupled to the data storage component and facilitates at least one of receipt, execution, and creation of an object that conforms to the hierarchically structured data model. In another example, the industrial automation device can be employed to execute a workflow.

Claims

1. An industrial automation device, comprising:

a data storage component that retains at least a portion of a schema, the schema facilitates usage of a hierarchically structured data model by the industrial automation device; and

a processor that facilitates at least one of receipt, execution, and creation of an object that conforms to the hierarchically structured data model.

2. The industrial automation device of claim 1, the hierarchically structured data model is representative of a hierarchical organization of a factory.

3. The industrial automation device of claim 1, the hierarchically structured data model is based at least in part upon one or more if ISA S95, ISA S88, and OMAC.

4. The industrial automation device of claim 1, the schema facilitates instantiation of control modules within the industrial automation device.

5. The industrial automation device of claim 1, the schema facilitates instantiation of equipment modules within the industrial automation device.

6. The industrial automation device of claim 1, the schema facilitates instantiation of a unit procedure component within the industrial automation device.

7. The industrial automation device of claim 1, further comprising a proxy component that facilitates communications between the industrial automation device and a legacy automation device.

8. The industrial automation device of claim 7, the proxy component comprises a mapping component that maps data from a flat data structure to data that conforms to the hierarchically structured data model.

9. The system of claim 8, the proxy component comprises a bridging component that converts data that conforms to a first network protocol to data that conforms to a second network protocol.

10. The system of claim 9, the second network protocol is CIP.

11. The industrial automation device of claim 1, further comprising a security component that ensures that an operator is authorized to review requested data within the industrial automation device prior to providing the operator with the requested data.

12. The industrial automation device of claim 11, the security component administers security to a plurality of industrial automation devices.

13. The industrial automation device of claim 1, further comprising a filtering component that filters data within the industrial automation device based at least in part upon user identity.

14. The industrial automation device of claim 1, further comprising an interface component that facilitates provision of data within the industrial automation device to a remote entity.

15. The industrial automation device of claim 1 being one of a programmable logic controller, a numerical controller, a robotic controller, a smart device, a switch, a network, and a router.

16. The industrial automation device of claim 1, further comprising an aggregation component that aggregates data from a plurality of industrial devices and makes such data available to higher-level systems.

17. The industrial automation device of claim 1, further comprising a workflow engine that facilitates execution of a workflow.

18. The industrial automation device of claim 17, the workflow engine executes Business Process Execution Language.

19. A methodology for enabling utilization of structured data within an industrial automation device, comprising:

21. The methodology of claim 19, further comprising ensuring that an entity requesting access to the industrial automation device is authorized to access such device.

22. The methodology of claim 19, the hierarchically structured data model is based at least in part upon one or more of ISA S95, ISA S88, and OMAC.

23. The methodology of claim 19, the industrial automation device is one of a numeric controller, a robotic controller, a programmable logic controller, a smart device, a switch, a router, a proxy, and a gateway.

24. The methodology of claim 19, further comprising:

receiving data that is structured in a flat manner; and

utilizing templates to convert the data so that it conforms to the hierarchically structured data model.

25. The methodology of claim 19, further comprising:

receiving data that is formatted in accordance with a first industrial protocol; and

re-packaging the data so that it can be transmitted by way of a second industrial protocol.

26. The methodology of claim 25, the second industrial protocol is CIP.
