Retrieves the value of a named control or indicator as variant data.
Use Variant to Data to convert the data to another data type.
A reference to a VI.
Use Open VI Reference or Static VI Reference to obtain a valid reference for this input.
Label for the control or indicator whose value you want.
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
Unchanged reference to the same VI.
Value of the control or indicator.
Error information.
The node produces this output according to standard error behavior.

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.
For optimization purposes, the application does not store data values of controls and indicators for any VI until you display the panel or call this node with a reference to the VI.
The first time you use this node to retrieve data from a referenced VI without first opening the panel, this node returns the default values of the control or indicator rather than the actual values. Thereafter, it returns the actual value.
