Thanks for your answer! I thought of using the shift registers in combination with a while loop. But I could not get this to help me realising a SubVI with a back-loop.
The thing is, that I want to realise a function with a back-loop within a subVI while the back-loop is positioned outside of the subVI. This is to e.g. read a bundled output of the subVI in the mainVI, unbundel it it in the mainVI, choose one of the list-items in the mainVI, give this as back-loop input to the subVI. I could not realize this by using a while loop with sift registers. Thanks for any further help! Andreas Hegenbart
