Abstract

An industrial data indexing system facilitates discovery and indexing of plant-wide data residing on multiple different data platforms. The indexing system automatically inventories industrial devices and other data sources located throughout a plant, and identifies available data items on each data source. The indexing system indexes the discovered data items in a federated data model that can subsequently be searched to locate data items or tags of interest. The federated data model records references to data items found on different types of data sources, including but not limited to industrial controller programs, human-machine interface applications, data historians, device documentation stores, inventory tracking systems, and other such data sources. The indexing system also discovers and records interdependencies between data items, which can be used to improve relevancy of search results returned to the user.

Claims

1. A system for indexing industrial data, comprising:

a memory that stores computer-executable components;

a processor, operatively coupled to the memory, that executes the computer-executable components, the computer-executable components comprising;

a discovery component configured to discover available data items distributed across multiple data sources of an industrial environment, wherein the multiple data sources comprise at least a first data source corresponding to a first data platform and a second data source corresponding to a second data platform; and

an indexing component configured to generate a searchable federated data model that records respective locations of the data items based on information about the available data items generated by the discovery component.

2. The system of claim 1, wherein the discovery component is configured to deploy a discovery agent on a plant network and to receive information regarding the available data items from the discovery agent.

3. The system of claim 2, wherein the discovery agent is configured to identify a data source, of the multiple data sources, on the plant network and to identify one or more data items available on the data source.

4. The system of claim 3, wherein the data source comprises an industrial device and the discovery agent is configured to identify the one or more data items based on an analysis of at least one of a control program executing on the industrial device, a configuration file on the industrial device, or a tag list defined on the industrial device.

5. The system of claim 1, wherein at least one of the first data source or the second data source comprises at least one of an industrial device, a knowledgebase storage device, a device documentation storage device, a work schedule storage device, a maintenance record data storage device, or an electronic communication log storage device.

6. The system of claim 1, wherein at least one of the first data source or the second data source comprises an industrial controller, and the discovery component is configured to discover, as one of the available data items, a reference to a data tag in a control program executing on the industrial controller.

7. The system of claim 6, wherein the discovery component is further configured to identify one or more related data items having a functional relationship with the data tag in the control program based on analysis of the control program, and the indexing component is configured to record the functional relationship in the federated data model.

8. The system of claim 1, wherein at least one of the first data source or the second data source comprises a human-machine interface application, and the discovery component is configured to discover, as one of the available data items, a reference to a data tag on a display screen of the human-machine interface application.

9. The system of claim 1, further comprising a transform component configured to normalize the information about the available data items according to a common namespace format.

10. The system of claim 9, wherein the transform component is further configured to tag one of the available data items with contextual information, wherein the contextual information comprises at least one of a plant identifier, a production area identifier, a machine identifier, a product identifier, an employee identifier, a product identifier, an alarm condition, or an actionable data flag.

11. The system of claim 1, wherein the discovery component is further configured to identify at least one interdependency between two or more of the available data items.

12. They system of claim 1, wherein

the discovery component is further configured to receive a sub-model from another system for indexing industrial data, wherein the sub-model represents an industrial system within the industrial environment;

and

the indexing component is further configured to integrate the sub-model with the federated data model.

13. A method for discovering an indexing multi-platform industrial data, comprising:

deploying, by a system comprising a processor, a discovery agent on a plant network of an industrial environment;

receiving, by the system, information from the discovery agent about available data items located on multiple data sources of the industrial environment, wherein the multiple data sources comprise at least a first data source corresponding to a first data platform and a second data source corresponding to a second data platform; and

generating, by the system, a federated data model that indexes respective locations of the data items.

14. The method of claim 13, wherein the deploying comprises configuring the discovery agent to identify at least a subset of the available data items residing on an industrial device based on an analysis of at least one of a control program executing on an industrial device, a configuration file on the industrial device, or a tag list defined on the industrial device.

15. The method of claim 13, wherein the deploying comprises configuring the discovery agent to identify at least a subset of the available data items residing on an industrial controller based on discovered references to one or more data tags in a control program executing on the industrial controller.

16. The method of claim 13, wherein the deploying comprises configuring the discovery agent to identify at least a subset of the available data items residing on a human-machine interface application based on discovered references to one or more data tags on a display screen of the human-machine interface application.

17. The method of claim 13, further comprising transforming the information to conform to a common namespace compatible with the federated data model.

18. The method of claim 13, further comprising tagging at least one of the available data items with contextual data, wherein the contextual data comprises at least one of a plant identifier, a production area identifier, a machine identifier, a product identifier, an employee identifier, a product identifier, an alarm condition, or an actionable data flag.

19. A non-transitory computer-readable medium having stored thereon instructions that, in response to execution, cause a system comprising a processor to perform operations, the operations comprising:

deploying a discovery agent on a plant network of an industrial environment;

receiving information from the discovery agent about available data items located on multiple data sources of the industrial environment, wherein the multiple data sources comprise at least a first data source corresponding to a first data platform and a second data source corresponding to a second data platform; and

generating, a federated data model that indexes respective locations of the data items.

20. The non-transitory computer-readable medium of claim 19, wherein the operations further comprise transforming the information to conform to a common namespace compatible with the federated data model.
