C-script based counter(or relay ) works at wrong frequency

1

I am utilizing C-Script to realize a counter, I set the frequency at 10kHz, however,my result shows that my counter works at a double speed.

And my code is as follows:

static int count2=0;

if (IsMajorStep)

{

if(InputSignal(0, 0) >0.6&&InputSignal(0, 0)<=0.9)

{

count2++;

}

if(count2>=600){

OutputSignal(0, 0) =1;

}

else{

OutputSignal(0, 0) =0;

}

}

I reckon that the counter will reaches the peak value every 0.6 seconds ,but in fact,the conter reaches the peak value every 0.3 seconds, so what’s wrong?

I reckon that maybe it’s just a problem of Rising edge and falling edge of the c-script?Maybe a signal has been counted for twice?
