Overload groups determine how a node should automatically behave based on how you
connect different data types to it in your diagram.
In an open project, select File»Preferences and click Preview features.
Check the Enable Multi-Mode Elements and overload groups
and click OK.
Click Yes to restart LabVIEW NXG.
When LabVIEW NXG launches, open your project.
Select a node you want to add to the overload group.
In the Document tab, expand
Behavior and enter a name for the overload
Overload groups work best when the individual nodes included have all but
one parameter in common. If the node parameter configurations are
significantly different, the algorithm which evaluates the overload group
may not behave the way you expect.
Repeat this for all nodes you want to add to the overload group.
Connect a wire to a node on your diagram that belongs to an overload group,
LabVIEW NXG evaluates whether the node on the diagram is the best match for the
If LabVIEW determines that
another node in the overload group is a better match, it will automatically
switch the node in the diagram to that node.
