Hello i am Danny.
Just start with labview basics, but i can use some help.
I have a (pressure) signal from a QuantumX MX840B. The signal is from a pressure vessel and i want te count how often the barrel is at 8 bar.
This is working but it counts continulously. so i need a kind of stop or reset.
thanks

You acquired data once and Just Increment in a loop, Even the Acquisition should be inside loop and Incremet the counter only when it is above 8.
use Shift registers to hold the previous count.

I just use Shift registers and put a slide i it. so it easy to test.
The pressure signal is sometimes hours above 8 (bar) and the counter should only add 1 at a time.

Even your Acquisition logic should be inside the loop.
Its Simple add/Increment whenever Pressure signal (in bar) is above 8, else hold with the old value using shift register.

the is no PtByPt BooleanCrossing in my labview.
is there another solution?
i try to update

Hi Daan,
are you really using such a tiny font size on your computer???

Thanks Palanivel
Unfortunately this is not the solution, the counter must stop at 1 now he count continues.
when the pressure vessel is empty it will pumped fully with air. when it is at 8bar a 2 must be made of the 1
i am updating labview!

I found a solution, maybe a bit cumbersome but it works for me.
thanks for help.
