Giving the error message the benefit of the doubt for the moment, are you sure the DAQ device you are using supports this event? Not all do.

What device(s) do you have?

hello

The device im using is USB-6341 multifunction DAQ, i dont know exactly how to use DAQ events, so if you have an example i'll appreciate it

thanks!

Well its fairly straight forward that a digital in line will never accumulate a terminal count A Counter Output Event is only available for counter input tasks.

The DAQmx help file lists the events and a discription of what they do.  You are probably looking for a change detection event.

In fact, im looking for a change detection
