But how? Can i put two conters work in parallel accioned by the same trigger signal.

Hi,

Can you be more specific.
What do you want to do?
What software do you use? What version?

I speak french, so if you prefer you can explain me what you want to do in French.

I'm not sure about what you mean by "two conters work in parallel accioned by the same trigger signal" if you are using DAQmx (I don't know anything about DAQtrad ...) it is of course possible to have 2 counters working at the same time.

Please discribe more accuratly what you need and also you can check DAQmx example VIs Help >> Find examples... >> Hardware Input and Output >> DAQmx 😉

Could you post your code please ?

i would like make the output off one counter (counter0)be the gate off another counter (counter1) but for this i need start the two counters simultaneously and then the labview give me the error 50103

There is a simple example two counters one counter is a clock for another one.

This example dont work i don´t know why.

I have had 8 counters running in parallel using a 6602 , essentially you use buffered counting on each channel with a shared trigger/gate and each uses their own source.  The gate signal can be external or intrinsically generated from the card.  Be aware that if you make a pulse train from the board you end up using up one of the counters and then can not have two channels anymore.  Post some more details on the counter/timer message board.
