Abstract

A distributed historian framework is provided where historical data is collected in accordance with an organizational model of a hierarchical system that is distributed across various elements of an enterprise. A directory service operates with the organizational model to enable configuration of historian components within the organization and to enable data to be located within the organization. In one aspect, an industrial automation system is provided. The system includes at least one historian component to archive data within an organization. A common data model then exposes functionality and data of the organization to the historian component.

Claims

1. A computer-implemented method, comprising:

distributing a common data structure that models an industrial organization across at least two system devices residing, respectively, on a first tier of the industrial organization and a second tier of the industrial organization, wherein the common data structure models the industrial organization in terms of hierarchical organizational tiers, including the first tier and the second tier, and respective nodes representing the at least two system devices; and

sharing data collection and storage functionality between an embedded historian component residing on an industrial device of the first tier of the industrial organization and a middle tier historian component residing on a device of the second tier of the industrial organization using the common data structure, wherein the sharing comprises exchanging a network message between the industrial device and the device of the second tier that initiates at least one of collection and storage of first data from the first tier of the industrial organization by the middle tier historian component or collection and storage of second data from the second tier of the industrial organization by the embedded historian component.

2. The method of claim 1, further comprising sharing data collection and storage functionality of an enterprise historian component with at least one of the middle tier historian component or the embedded historian component using the common data structure, wherein the enterprise historian component resides on a device of the third tier of the industrial organization that is higher than the first tier and the second tier.

3. The method of claim 1, further comprising generating a historian interface, by a web server component, that interfaces to at least one of the middle tier historian component or the embedded historian component.

4. The method of claim 3, further comprising displaying, on the historian interface, time series data and event data.

5. The method of claim 1, further comprising exposing a functionality of at least one of the embedded historian component or the middle tier historian component using the common data structure.

6. The method of claim 1, further comprising configuring the middle tier historian to aggregate data collected by a plurality of embedded historian components including the embedded historian component.

7. The method of claim 1, further comprising locating data within the industrial organization using a directory service in conjunction with the common data structure.

8. The method of claim 7, further comprising distributing security services to the embedded historian component and the middle tier historian component using the common data structure and the directory service.

9. The method of claim 1, further comprising executing the embedded historian component on at least one of a controller, a controller module, a client, a server, a sensor, or a factory component.

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

configuring an organizational data model that models an industrial organization as a set of hierarchical organizational levels and a plurality of nodes representing at least two system devices, wherein the organizational data model is distributed among the at least two system devices residing on at least two levels of the industrial organization defined by the organizational data model; and

marking a data structure generated a first level of the at least two levels for historical collection by a first historian component residing on a first device, of the at least two system devices, located on the first level;

wherein the marking facilitates collecting and storing of the data structure by the first historian component, and

wherein the organizational data model facilitates exchange of messaging between the first device and a second device, of the at least two system devices, located on a second level of the at least two levels, the messaging transferring responsibility for the collecting and storing of the data structure to a second historian component residing on the second device.

11. The computer-readable medium of claim 10, wherein the marking comprises associating the data structure with metadata indicating a function of the data structure.

12. The computer-readable medium of claim 10, wherein the configuring the organizational data model comprises configuring the organizational data model to include, as the set of hierarchical organizational levels, at least one of an enterprise level, a site level, an area level, a line level, or a workcell level.

13. The computer-readable medium of claim 10, wherein the operations further comprise configuring a directory service that interacts with the organizational data model to facilitate discovery of data collected by the at least one of the first historian component or the second historian component.

14. The computer-readable medium of claim 10, wherein the operations further comprise configuring a third historian component to aggregate data collected by at least one of the first historian component or the second historian component, and wherein the third historian component resides on a third level of the at least two levels.

15. The computer-readable medium of claim 10, wherein the operations further comprise:

exchanging the messaging in response to determining that a data collection resource of the first historian component has become insufficient for collection of the data structure.

16. The computer-readable medium of claim 10, wherein the operations further comprise propagating a security service to at least one of the first historian component or the second historian component using the organizational data model.

17. A distributed historian communications method, comprising:

defining a common data structure representing an organization in terms of multiple hierarchical tiers and respective nodes representing system devices of the organization; and

distributing the common data structure among at least two of the system devices residing on at least two tiers of the multiple hierarchical tiers, wherein the at least two of the system components host respective data historian components;

wherein the common data structure facilitates;

collecting and storing, by a first data historian component executing on a first device of the system devices residing on a first tier of the at least two tiers, first data generated at the first tier,

collecting and storing, by a second data historian component executing on a second device of the system devices residing on a second tier of the at least two tiers, second data generated at the second tier, and

exchanging of a network message between the first device and the second device, wherein the network message initiates at least one of collection and storage of the first data by the second data historian component or collection and storage of the second data by the first data historian component.

18. The method of claim 17, further comprising propagating, via the common data structure, a security framework to the first data historian component and the second data historian component.

19. The method of claim 18, further comprising employing a directory service in conjunction with the common data structure to propagate the security framework to the first data historian component and the second data historian component.

20. The method of claim 17, further comprising exposing functionality of the first data historian component to the second device using the common data structure.
