How to avoid default value of control

[ClaudioH]

I am running LV 6.1 and one of My sub-vis has strange behavior: The input cluster control returns to defualt value during execution. I am not able to keep it with another value.

LV want data to execute a sub-VI.

To satisfy this need, it will fill in the default value any time a control that is wired to the icon connect does not have anything wired to it.

You can over-ride the default by wiring to the connector where sub-VI is called.

There other variations on this theme, but this is the answer to your query as posted.

What controls are in your cluster?
If you have buttons, check the mechanical action: latch when pressed or latch when released will return to the default position after the control is read. Switch when released (or pressed) won't return to default. Right-click on the button control and select Mechanical action.
If you're using numerics, check the data range and the action if value is out of range: if your range is too small and the control is set to Coerce when out of range, you could see the default value instead of the value you entered. Right-click on the numeric control and select Data range.
If this doesn't help, post your vi.
