Issue Details

How do I set a default sequence file to load in the operator interface using LabVIEW? I would like a specific sequence file to always load once the operator interface opens.


  1. You may find the LabVIEW source code for the operator interface at C:\Users\Public\Documents\National Instruments\TestStand 20xx (32-bit)\UserInterfaces\Simple\LabVIEW\Source Code.
  2. Open the Top-Level VI from the LabVIEW project (TestExec.llb)
  1. Navigate to "Start Application" from the case structure.
  2. Insert an invoke node as shown in the red square. Click on Method to expand the list of options available and select OpenSequenceFile option.
  3. Create a string constant to input the sequence file path.
