Define reusable tag structures

A Supertag is a template for a set of related tags. The tags that belong to a Supertag template are associated with the common properties of a component in a manufacturing process.

The Supertags save development time. Instead of creating a set of tags for every component in the manufacturing process, you can replicate a single Supertag template and create individual instances for all process components that have the same properties.

Supertag Templates

The figure below shows a single Supertag template consisting of a set of related tags associated with pump data. The template can be replicated to create instances of the Supertag of the identical pumps in the process.

All tags that belong to an instance of a Supertag behave exactly like normal tags. The member tags can be assigned as InTouch discrete, integer, real, and message data types. The tags support trending, alarming, and all tag dotfields.

A Supertag template can organize its member tags in two nesting levels. A Supertag template can contain up to 64 embedded child tags. Each child tag can contain up to 64 sub-member tags. This gives you a total of 4095 tags in a Supertag template.

The following figure shows how tags are organized within a Supertag template.

When one Supertag template parent is embedded into another Supertag template, the embedded tag becomes a child member.

After you create a Supertag parent template, the Tagname Dictionary lists it as a tag type in the Tag Types dialog box. The template can be selected immediately as a tag type when you create a new tag. You do not need to restart WindowMaker to define tags that use a newly created Supertag type.

Saving Supertag Templates

By default, all Supertag templates are saved in the Supertag.dat file in the C:\ProgramData\Wonderware\InTouch folder. You can choose to save the Supertag templates at a different location.

Specify the location to save the Supertag templates

1. Open WindowMaker

2. On the File menu, select Configure, and then select WindowMaker.

   The WindowMaker configuration screen appears.

3. In the Supertag path text box, specify the location to save the Supertag templates.

4. Select the Store Supertags data in application directory check box to store the Supertags data in the application directory. This will override the path specified in the Supertag template path field.

   Note: If you want to export supertag templates, then you can select this check box and export respective InTouch application. For more information refer to Export InTouch applications to use as a template.

Import Supertags

To import the Supertags during the InTouch Application migration, see Import Assets during InTouch Application Migration.
