VI fetches always same data from digitizer

Why would you need a reference and why would you need to pass it into a FOR loop???

 you typically want to put references in shift registers across FOR loops.

Those are your words

I was talking about the IO tasks here, i.e. the following tunnels should be shift registers.

I was using the term "references" generically: references (VI, control, etc.), DAQMx tasks, refnums for file IO, etc. etc.

(Anything that should retain the input value unchanged if the loop iterates zero times. A plain tunnel would output the default datatype in that case).

Ah Ok, thanks for that.
