  • igenclassrntag.png Handshake Out —

    Handshake Out returns Handshake In if Handshake In is wired. Otherwise, Handshake Out returns the handshake item that you specify in the Handshake Method Node.

    • If you use a VI-defined handshake item in a reentrant FPGA VI, LabVIEW creates a separate copy of the handshake item for each instance of the VI to avoid resource conflicts.

    You can create a VI-defined handshake item with the same name as a target-scoped handshake item. You also can create VI-defined handshake items with the same name in different VIs. However, you cannot create multiple VI-defined handshake items with the same name in the same VI.
