Count number of iterations of a sub-VI to output accordingly

Hi all,


For the last few hours I have been trying to figure this out, but haven't managed, so I ask for your help please. I have a sub-VI that needs to output the next element of an array every time is gets called from the parent VI. If I there was a way to know the number of iterations of the sub-VI, then I could use this as a parameter to determine which element of the output array to return.


Thank you very much in advance for your help.

You will need an uninitialized shift register to keep track of the index (or count number) in the SubVI.

Have a look at the Action Engine thread.

That or a feedback node. Put down an increment function and wire the input to the output and one should magically appear.
