How can I make a serial number verifcation vi for a 4 uut panel?

[jblpep]

I'm a newbie to Labview and need to make a scan out system for our uuts. I'm using labview 7.1 and teststand 3.1. Here's my scenerio.

When executing test uuts we display a panel for four uuts. Each uut is scanned in and tested individually. What I need to do is add a vi at the end of the test that prompts the user again to scan in the serial number for each slot. Then the script would compare that serial number to the one they originally scanned in for that slot. If they didn't match then the board would need to be retested.

My main question is how can I call the original serial number/slot #  variable in labview? Is this stored somewhere in teststand?. Any help is greatly appreciated.

I'm assuming you are using the parallel model. In that case, each serial numbr will be stored in RunState.Root.Parameters.TestSocket.UUT.SerialNumber.

I have the testand options set to "4" in the # of uuts so I assume this is the parallel model. Can I pull that variable into a vi?

Absolutely. You can pass it directly in through the VI's connector pane or pass the sequence context and use the TestStand - Get Property Value function.

I would suggest you study the shipping document called Using TestStand with LabVIEW. It's part of the TestStand Bookshelf on the help menu.
