[Aaron_W.]

Overview

This VI demonstrates how to programmatically determine if a sub-VI or VI is running on your computer.

Requirement

LabVIEW Full Development System 2012 or compatible

Steps to Implement or Execute Code

1. Enter the path of the VI to determine its status
2. Run the VI, The VI will return the following Execution States:
   Bad—VI has errors and cannot execute or VI is not currently running
   Idle—VI is not running, but is in memory.
   Run top level—VI is the top-level VI in an active hierarchy.
   Running—VI is reserved for execution by one or more active top-level VIs.
