Configure and Create Tag (G Dataflow)
Creates a tag endpoint based on the input data type and tag-specific configuration settings.
Use this node when you want to create multiple tags in loops.
initial value
The first value you pass to the tag, which is read from the tag immediately after it is created, and before any write operations are performed.
This input adapts to any supported tag data type, which determines the data type of the tag. Subsequent values you write to the tag overwrite this value.
Default: 0
timestamps?
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
tag ref
A reference to the tag endpoint that this node creates.
error out
Error information.
The node produces this output according to standard error behavior.

What Is a Tag?
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.
What Is a Tag Proxy?
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.
