Edit extended properties for a discrete tag

Extended properties can be used to add application-specific metadata to tags. When you search for tags in AVEVA Historian Client Web or AVEVA Insight, you can locate tags based on these property values. Likewise, with SQL queries you can select tags based on these property values without needing to know the tag name.

The following extended properties are predefined by the system, and can be added to any discrete tags:

• Alias - Used as the tag's preferred label in charts.

• Location - Places the tag within the asset model of AVEVA Insight.

You can define your own custom extended properties by using the database import/export feature. See Add new tag extended property values for more information.
