Complete the following steps to determine the current instance of a subVI.
- Suspend execution of the subVI.
- Select the Call list pull-down menu that appears on the toolbar. The menu lists the chain of callers from the top-level VI down to the subVI. This is not the same list you see when you select View»Browse Relationships»This VI's Callers, which lists all calling VIs regardless of whether they are currently running.
- Select a VI from the Call list menu to display its block diagram and highlight the current instance of the subVI.
You also can use the Call Chain function to list the chain of callers programmatically.
