Hi Kizkas,

 

I don't see anything in your task that would be forcing that value to 0 every time. Are you sure that your task is being triggered to start? Do you have the right trigger source selected? Are you sure that the signal you are reading has proper logic levels so that the counter can register those as high or low? These are some things to check. It doesn't really look like you are doing anything wrong in the DAQmx task.
