Pass serial number to TestStand from operator interface to trigger test

[avater]

In TestStand,we know(sequential model) PreUUT dialog is the start of the test.However,I have a operator interface in labview that I want to scan serial number on the OI and OI will pass the serial number to TestStand and then trigger the test.Of course,PreUUT will be rewrite to disable the dialog in the sequence file.

I have a idea that in PreUUT I have a step in looping quering a variable which will be set by Labview.But you know,before a teststand sequence run,I don't have the handle of SequenceContext from which I can set TestStand variable.

Any suggestions?Thanks.

You need to use a UI message.  It is the proper way to accomplish this.  You are on to something by doing it in the PreUUT.  Pass the sequence context to the UI through a UI Message and then in the event callback you can set a variable (Parameters.UUT.SerialNumber) to the value in the LV FP control.  Here are some documents-

Look at the example- Sending Data from the TestStand User Interface to an Executing Sequence (LabVIEW)

Hope this helps,
