Counts too slow on powerful DAQ - Read from one digital channel.

[08anja]

Hi, 

Im blinking an LED's and counts how many times it goes high/low (true/false). The LED is connected to my digital channel P0.7 on my DAQ 6351. I configured  some of the examples from LabVIEW Help, but my problem is, when I count, it only counts around 120 and it is supposed to count 150 times in 10 seconds.

What is it in my systems that I can't count the last 30 times? Is it my DAQ.mx Read or something else? 
It's pretty important for mu further system, that it counts correct.

The true/false case at the buttom is just what is inside my first true-case. 

Thanks in advance!

That board has a counter, so just use it and make your life easier.

And beside using hardware features as already suggested: learn to use shift registers!
