Link indicator readings on a sub vi to a front panel on a main program in real time

[Josh.G]

Hello I am trying to link indicators on a sub vi to indicators on a main program in real time. The sub vi is set-up to perform data acquisition and I want to be able to show that data acquisition in real time on the main program front panel, how do I accomplish this?

Hi Josh.G,
you can use the references from your main vi. Create an array of these references and connect it to your subvi. There you can use a prperty node to write the new value. Another way is to use queues or notifier. Write the data into one of them and read it in your main vi, if you have time for it.
Hope it helps.Mike
