Hello. I'm using Teststand and have been got stuck on a problem now.
Whenever I communicate to a LabVIEW VI which is activated as a functional global, I purposely displayed the LabVIEW VI on front pannel to make sure the data communication.
However once I released the check mark 'Show VI front pannel when called' , the data transmission including receiving vanished. As a matter of fact, always the numeric data resturns ' 0 '.
So the data communication must be transacted with a shift resgister function at each step in Teststand, so it always provides a command to the functional global VI for an e-num item selector.
Therefore it looks the shift register function doesn't work at the point anymore in the functional global VI.
Otherwise as long as I suspend the VI as a display, checking on the box 'Show VI front pannel when called' , I exactly can make sure the data communication , receiving the command and returning the data.
Have you heard that kind of unusal problem before?
Do you think it happened due to data communication or just simply Teststand applicational error?
If it has some useful information, I try to fix them.
Thank you.
Noriyuki
