During the very first start-up of the interface, the AF element hierarchy is created. Here is an example of the PI AF elements that are created when an interface is configured to communicate with a PIWebAPI endpoint.
Note: CONNECT data services does not currently support static structure. The two streams that are created by setting an CONNECT data services endpoint communicate dynamic data.
Examples
This is what the PI AF structure would look like for a host called SRVTEST and an interface service called PI_UFL2. It is one of three instances of installed PI Interfaces.

The static attributes of the aforementioned elements are shown in this table and the screenshot that follows:

Note: In the example image above, three additional fields _id, _indexPropertyIndexer, and _namePropertyIndexer can be seen. These attributes are used for internal purposes only and can safely be ignored. Additionally, these attributes are created as hidden attributes by default, and viewing of them can be disabled if so desired. Refer to the PI System Explorer User Guide for further instruction, specifically the section on how to disable the viewing of hidden attributes.
