Use indirect tags with local tags

Indirect tags are typically used with tags defined in a local Tagname Dictionary. An indirect local tag enables you to create visual objects that show multiple attributes of a local tag. For example, you can create a faceplate within an application window. The faceplate contains selectable items with links to an indirect local tag assigned to different dotfields. In the following example, operators modify dotfield alarm limits linked to a local indirect PumpRPM tag.

The following figure shows a faceplate with animation links to pump RPM alarm limits. An indirect tag assigns the attributes of different local tags to the alarm limit faceplate.

To redirect the faceplate to the appropriate tag, include a statement within a QuickScript.

Indirect_tag_name.Name = "tag_name";

In this script example, tag_name is the name of an actual tag defined in the local Tagname Dictionary. When the script runs, all dotfield values associated with this local tag become accessible to the application object through the indirect tag.
