Browse the model hierarchy in a Historian client

You can browse the ArchestrA model view hierarchy in any AVEVA Historian client that incorporates the Public Groups folder in the navigation tree, such as the Historian Trend client.

It is recommended that you not modify the model view hierarchy replication either directly from the database or by using an application such as the Historian Trend client.

To browse the model hierarchy

1. Start a client, such as the Historian Trend client.

2. Connect to the Historian.

3. In the navigation tree, expand Public Groups.

4. Expand the group that reflects the name of the Galaxy you want to browse.

   

5. Navigate through the ArchestrA model view hierarchy and select a group representing an object with historized attributes.

6. Select attributes for which you want to view history data in the client.

For example, when you select a group in the Trend Tag Picker, the Tags pane shows a list of all the Historian tagnames representing the historized attributes of the selected group (object).

If only the objects at the bottom of the model view hierarchy are deployed, the names for the objects higher in the hierarchy are not available to clients. To enable replication of the hierarchy in other applications, ArchestrA generates generic names for the undeployed objects. Client applications display these generic names instead of the actual names that appear in the IDE.
