Running a shown Labview VI alongside Teststand

[MechUnit]

Hello Community,

Using Teststand 2014 32bit & Labview 2015 32bit.

I am trying to run a VI along side Teststand that I can update throughout the test procedure.

For example, I have a VI with a single 2D image control and a string indicator. The string indicator is for a barcode. The 2D image determines Pass or Fail. I have a sequence file that will call this VI in a new thread to be shown throughout the test procedure. When the user runs the sequence file, the person will be prompted with a popup to enter a barcode. Once the barcode is entered, I want my 2D image to appear on the VI signifying that a DUT is present. After the sequence test completes, I want to change the 2D image to green (pass) or red (fail).

I have a Main Labview GUI that calls my Teststand sequence files. Now I want to add this new VI thread called from that sequence file and receive updates? I am using UIMessages to update the Main Labview GUI, but what can I use to update the new VI being called in the sequence? I am trying this out as a simple example test, but it will later be used for a batch sequence to test 10 DUTs. Is this possible or should I merge this new VI thread into my Main Labview GUI?

Sorry if this all sounds confusing. Please let me know if you have any questions.

I am trying the Get/Set Properties, but they do not seem to be working.

I want the VI indicator in the new thread that is running along side Teststand to update once a barcode is scanned.

Then at the end of the sequence, change the boolean to True to end the GUI.

Any help will be greatly appreciated.

This sounds like it could be a good use case for Synchronization Objects. I'm attaching a basic example that uses a notifier to do something similar to what you've described. I wouldn't recommend handling serial numbers like this, but it gets the point across. You can also find a better example on notifiers here.

Hope this helps!
