reset counter

[wa5ycg]

I can not find a way to reset an M-series counter back to zero when using it as a simple event counter using LabVIEW and NI-DAQmx.  I am using a PXI-6229 and LabVIEW 8.5.1.  Can anyone suggest a way?

Here is an example if stop/restart the task is an acceptable solution.

Software solution :

Write the current value of the counter to a shift register of the while loop and then substract it from the new values.

this might work ...

use DAQmx configure channel property node

Counter Input

    Count Edges

           Initial Count

set Initial Count to 0

not sure if you can do this while the task is running, you might need to stop the task / reset the count / restart task

Unfortunately this property is not allowed while the task is running.

Reset is superfluous if stop/restart because the counter will anyway restart at the initial count.
