Determine tag usage

The InTouch HMI maintains a use count for all tags defined in the local Tagname Dictionary. The tag count does not include internal system tags.

Remote tags are not defined in the Tagname Dictionary. InTouch increments the tag count for each reference within an application to a remote tag. For more information about how InTouch counts a remote tag reference, see Determine maximum number of remote tags based on licensing.

Before you delete unused tags, make sure that you complete the following tasks:

• Close WindowViewer.

• Update local tag counts and references to remote tags.

• Produce a Cross Reference tag report.

• Locate tag usage within an application with the Cross Reference Utility.

• Save your application in WindowMaker.
