Pass Text from VI to main VI in real time

[lmontoya]

I have a big application with many sub-VI's, every sub-vi is a complex VI where, I'm reading, saving and changing values to an external microprocessor. normally every sub-vi take 1, 2, 3, or more minutes to compleate but the operator can see just the main VI. how can I display in the main VI, the text generated in any Sub-VI in real time? because the operator need to see the status of the test in real time and not to wait until the sub-vi finish to see the result.

Thank you

You can use functional globals, queues, notifiers to transfer data between VIs. Try to look up info on each one of them and if you have any questions, please post back.

You can also pass a reference of the indicator to the subVI and it can write to it directly. Examples ship with LabVIEW to show you how to use references, as well as the other options mentioned in the previous reply.
