Issue Details

I have steps in my TestStand sequence file that call LabVIEW VIs. I want to update or refresh my VIs and their prototypes all at once.


  1. In the TestStand Sequence Editor, navigate to Tools >> Update VI/LV NXG VI Calls.
  1. Select the desired Files to Update and Type of Calls to Update options. You can choose to update only the open sequence, all the sequences in a directory, or specific sequence files. For more information on the options, refer to TestStand Help: Update VI/LV NXG VI Calls Dialog Box.
  1. Click on Update Calls.
Note: The Update VI Calls option is not available in TestStand 4.0.1f1 or earlier. Instead, you can use the TestStand API to programmatically reload module prototypes on all steps within a given sequence file. Refer to Reloading Module Prototypes For All Steps In a TestStand Sequence File for an example.
