A tag is single-point, latest value data that you can access from multiple documents within a project. A tag can store a single value of any data type that represents the state of a process. Tags are similar to global variables in text-based programming languages.
You can create a tag either dynamically, using the Configure and Create Tag node on the diagram, or statically, in the shared resource collection file.
You can create a tag to access the same data from multiple VIs within a project.
A tag proxy is a reference that is local to part of the application that mirrors the value of the actual tag to which it is linked in another location in the application. You use a tag proxy to access data that is in another location in the application. You can read from and optionally write to a tag proxy only after the tag proxy links to a tag.
Complete the following steps to statically create and configure a tag.
Where This Node Can Run:
Desktop OS: Windows
FPGA: All devices
Web Server: Not supported in VIs that run in a web application
