Creating Control Reference SubVIs from Property Nodes
Complete the following steps to create a subVI that includes a control reference directly from a Property Node.
Right-click the front panel object or its block diagram terminal for which you want a control reference subVI and select Create»Property Node from the shortcut menu to create a Property Node implicitly linked to the object.
Use the Positioning tool to select the new Property Node and select Edit»Create SubVI. LabVIEW automatically creates a control reference to the control on the block diagram of the main VI, creates a subVI that contains a control refnum wired to a Property Node, and wires the control reference on the main VI to the control refnum input terminal of the new subVI.
Note Select several Property Nodes at once to create a subVI with multiple control refnums and Property Nodes.
Double-click the subVI to open it. Modify the Property Node and other elements of the subVI as you do in any other VI.
