Hi, in gx developer, for up down counter, if sufficient number, pilot light goes on. How to turn off the light if the counter has decreased without push reset button?

Probably, do not use the output or done bit of the counter.  Rather do comparison on the accumulated value of the counter and the preset.

Yes, the output will turn off any time the D10 is less than D20 and turn on anytime D10 is greater than or equal to D20.
