1. An industrial automation system, comprising:
- a plurality of historian components configured to archive data within an organization, the plurality of historian components distributed at multiple hierarchical levels of the organization;
a common data model representing the organization and distributed among system components residing on one or more levels of the organization to yield at least one distributed common data model, wherein at least one of the plurality of historian components is associated with a corresponding one of the at least one distributed common data model; and
a directory service configured to operate with the common organizational data model to enable automatic discovery and exposing of at least a first of the plurality of historian components to at least one of a second of the plurality of historian components or one or more of the system components,wherein one or more of the plurality of historian components are configured to operate on at least one of a controller, a module, a chassis, a client, a server, a sensor, or a factory component, and wherein instructions associated with one or more of the plurality of historian components are executed on a processor operatively coupled to memory.

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.

18. A distributed historian method, comprising:
-
employing a processor executing computer-executable instructions stored on a computer-readable storage medium to implement the following acts; defining a plurality of hierarchical organizational levels in a common data model representing an industrial automation enterprise; distributing a plurality of historian components among system components residing on at least two of the plurality of hierarchical organizational levels; distributing the common data model among the system components to yield one or more distributed common data models; associating at least one of the plurality of historian components with a corresponding at least one of the one or more distributed common data models; archiving data generated by the industrial automation enterprise using the plurality of historian components and the common data model; and employing a directory service in conjunction with the common data model to enable automatic discovery and exposing of at least a first of the plurality of historian components to at least one of a second of the plurality of historian components or one or more of the system components. - View Dependent Claims (22, 23)

19. A distributed historian system, comprising:
- means for distributing a hierarchical data model of a control system among a plurality of system components comprising the control system to yield at least one distributed data model;
means for defining data structures to be collected in the control system; means for collecting the data structures using a plurality of historian components distributed among the plurality of system components, at least one of the plurality of historian components associated with a corresponding one of the at least one distributed data model; and means for employing the hierarchical data model to enable automatic discovery and exposing of at least a first of the plurality of historian components to at least one of a second of the plurality of historian components or one or more of the plurality of system components. - View Dependent Claims (20, 21)
