Configure extended tag properties

Extended tag properties let you add descriptive metadata to Historian tags. You use these properties to store information such as aliases, locations, or custom attributes that help you organize tags and make them easier to find in Historian clients and queries. Extended tag properties do not affect data collection or storage; they provide additional context for how tags are used and interpreted in your system.

You configure extended tag properties for individual tags by using the Configuration Editor in the Historian Server.

Configure extended properties for a tag

1. Open the Operations Control Management Console (OCMC) and expand the server group that contains the Historian Server.

2. Select Configuration Editor > System Configuration > Tag Configuration.

3. Select the appropriate tag type, such as Analog Tags, Discrete Tags, or String Tags.

4. In the details pane, double-click the tag you want to configure. The Properties dialog box opens.

5. Select the Extended Properties tab.

6. To edit an existing extended property:

   1. Select the property

   2. Select Edit Extended Property

   3. Enter the new value and select OK.

7. To add a new extended property:

   6. Enter a value, and click OK.
