Calls the VI to which a strictly typed VI reference refers. Like most diagram objects, Call by Reference executes synchronously, preventing data flow from continuing along its output wires until the referenced VI finishes executing. To run the referenced VI asynchronously while the diagram beyond the VI call continues executing, use Start Asynchronous Call instead.
The reference associated with a VI that is already open. The reference must be a strictly typed VI reference.
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 associated with the strictly typed VI reference.
Error information.
The node produces this output according to standard error behavior.

When you wire a strictly typed VI reference to the reference in input of Call by Reference, the node automatically displays the input and output parameters of the referenced VI. Wire data to the input terminals of Call by Reference to pass the data to the referenced VI. Use the output terminals of Call by Reference to access the data that the referenced VI returns.
