The Get Tag Information function returns the tag data type stored in Variant. This VI returns an error if Variant does not contain a tag.

A tag is a data type for system resources and is similar to a refnum. A tag is allocated in a static manner when a VI begins execution, while a refnum is dynamically allocated. One example of a tag is a DAQmx Device Name.

Note: The tag data type is installed with some add-ons, such as NI-DAQmx.
