Initializing VI Elements to Default Values

[diarmaede]

Hi All,

I know how to set values as default on the front panel.  However, when I run a VI multiple times without closing it, I need to re-initialize certain front panel values from their value at the end of the last run to the default values used in the next run.  Generally speaking, I do this using an "Init" state in a state machine or a first frame of a stacked sequence.  In either case, I just create a bunch of local variables and set the values to zero, or whatever other initial value they need.

When I was recently in Core 1 and Core 2 training, the teacher showed us a way to reset all these values without using local variables as described above.  But, for the life of me, I cannot remember what he said to do.

Any help jogging my rapidly-aging memory would be much appreciated.

Thanks!

Invoke Node on the VI to Reinit values to default.

Just to highlight a point. The node RavensFan presented resets ALL controls and indicators to their default values.

Thank you, gentlemen!

Additional info: if you want to reinitialize only specific controls/indicator, then you can create the corresponding invoke node for that control/indicator (right-click on control/indicator and select Create -> Invoke Node -> Reinitialize to Default).
