how can i use control reference to pass integer to a sub VI?

In your subVI (Sous3.vi), create a Numeric control on the front panel. Right-click on the numeric and choose "Representation >> I32." Ctrl-drag this numeric onto both the "Number In Refnum" and "Number Out Refnum." This will change them to integer control references.

Note that you should change your top-level VI (Principal.vi) to pass only integer control refnums to Sous3.vi.
