Call Chain

Call Chain

Returns an array of every VI that calls this node, from the current VI to the top-level VI.

The first element of the output array is the VI that calls this node. Subsequent elements in the output array are VIs that call the VI in the previous element. The last element of the output array is the name of the top-level VI.

If the current VI is a subVI, use this node to identify all the VIs that call the subVI.

Inputs/Outputs

call chain

The chain of calling VIs from the current VI to the top-level VI.

An Alternative Tool for Identifying Call Chains

You can also view the chain of callers from a subVI up to the top-level VI in the Call Stack section of the Debugging tab. The Call Stack list populates when you pause a VI that is called in other VIs.

Call Chain Behavior for a VI that Is Part of a Component

If a VI in the call chain belongs to a component, this node returns the qualified name of the VI, which includes the component namespace.
