GE Historian Data Source
The GE Historian data source allows you to connect to Historian servers to read from and write to Historian data tags. You add Historian tags to Workflow and then use those tags as data sources throughout Workflow.
Historian server names and display names are distinct from each other. A GE Historian display name can contain spaces and/or other special characters. A server name is the address of the GE Historian server and must comply with a valid Windows®computer name; however, the underscore character is permitted.

Tag Information
The following table describes the areas that allow you to view information about the GE Historian tags found in Workflow:
Item | Description | |
---|---|---|
Start Synchronization | Click to browse the current tag status and event details available on the selected GE Historian server. This button can also be used to perform a manual resynchronization of all tags in GE Historian with the tags visible in Workflow; however, this operation is normally performed automatically by Workflow. | |
View Tags | Click to open the Historian Tags dialog box to view the existing tags on the selected GE Historian server. | |
Remove Orphan Tags | Click to open the Orphan Tags dialog box and remove existing tags from Workflow that are no longer being accessed. When a tag is deleted from the GE Historian server, it is not automatically removed from Workflow; it is marked as orphaned so that existing data links to that tag are not broken. |
