NI 9263 remains at constant voltage after Labview exits

[mdalton]

Hi all,

I have a problem that when I write a waveform to my NI 9236 on a cDAQ 9174 it remains at a constant voltage after the Labview program finishes until I unplog the USB cable.  I would like it to go back to zero, so that I can leave it running by itself and not worry about burning the resistor for hours after the program finishes.  I tried putting a DAQmx Clear Task at the end of the program, but that doesn't seem to help.  Any ideas?

Thanks,

Matt

reset the device after clearing the task

This is a basic question that has been asked and answered numerous times. If you want the device to output a certain value, you need to program it to output that certain value. Add a DAQ Assistant or a simple DAQmx Write as the last thing your program does.
