Overview

This example shows a way to do DAQ task called by TestStand in a new thread.


Description
This sequence calls a VI that performs Analog Output (a Sine Wave) while the sequence continues then sends a UIMessage to the VI when it is time to stop.

The VI can be modified to perform any sort of Data Acquisition. This would be useful in an application when you must output a sine wave, pulse train, or any other signal which runs continuously while other tests are performed. You could also input signals to analyze later while continuing a sequence.

 


Requirements

  • LabVIEW 2012 (or compatible)
  • NI-DAQmx 12.0 (or compatible)
  • TestStand 2012 (or compatible)


Steps to Implement or Execute Code

  • Open the sequence file in the folder.
  • Run the sequence.
