How can I get to VI's that are executed before the main sequence

[kennethone]

Good afternoon,

I have been tasked with an existing TestStand project and I have little experience in this software.

I have a seqeunce that begins execution by asking for a serial number entry. I need to modify this sequence step. I don't need t modify the VI itself, which is pretty easy to find, but I need to modify the conditions of the step.

However, when I place a breakpoint in the Main Sequence on the very first step (first step in the Setup sectio, I also place a breakpoint in the first step of the Main section) , TestStand asks for a Barcode entry before the breakpoint is reached. Therefore I cannot find the entry point for this seqeunce and the location in the sequence where the bar code scan takes place. I need to find it because I need to change the output and some parameters of that step.

I need to know why this occurs and how I can each the pre-execution steps. 

Unfortunately  I cannot show or share this sequence, so I am relying on community knowledge on this issue. This is NI Teststand 4.2.

Thank you very much,

Look at the callbacks that are in the sequence. Do you see a pre-uut one?

Try setting a breakpoint in the PreUUT sequence of your process model or the PreUUT sequence in your client sequence file if there is one (that also might be where the code you are looking for is located - that's usually where code like this lives.).

Hope this helps,
