Error 1

[jereger]

Hello,

I'm trying to build a producer/consumer loop to process Boolean data from a single digital line, but I keep receiving an error. I have attached a image of the error box and my vi below. I have done my best to trouble shoot it with no success. Can anyone see the cause of this error?

Case structure in lower consumer loop.  You made the mistake of having your tunnels set to "Use Default if Unwired".  As a result, you didn't get an error when you failed to wire through the file reference in the false case.  So you lose file reference when the false case executes thus getting error 1 when you do want to use the file reference.

FIX:

1.  Right click on tunnels and uncheck "Use Default if Unwired".

2.  Fix the VI that will now be broken by wiring through the reference wire in the false case.
