Create and configure a tag to track the most recent value of a piece of scalar data.
Use tags when you need to see a single data point changing in real time.
In LabVIEW, you can create and configure a tag programmatically with the Tags API in the Skyline folder on the Data Communication palette. In NI SystemLink Web Application, you can create and configure a tag in Tag Viewer. This procedure describes how to create and configure a tag in NI SystemLink Web Application.
After you have created and configured a tag, use the Tags API in LabVIEW to write values to tags, read tags, query tags, and perform other operations.
