Modifying LabView program in http://www.ni.com/example/31410/en/

I'm trying to modify the LED lighting vi (at the link below) to make it turn of the LED after a specified time, like 50s, instead of having to click on the boolean switch on the front panel to turn off the LED. Does anyone have a simple solution?

Look into the "elapsed time" express VI.

Thanks BALUG for the response. The Elapsed Time Express VI appears to be available only as an added functionality on certain NI devices. My device is NI-USB-2002.

Elapsed Time Express VI is a function that is within LabVIEW.  All versions.  It has nothing to do with devices.

And what is USB-2002?  I can't find any record of NI having made one with that number.

[SimJock]

That was a typo. I meant NI-USB-6002. I also didn't have any success with NI-USB-6008.

Thanks. I looked again and found the express vi under Execution Control.
