USB-6351 Analog IN / Digital OUT simultaneously

[spongysponge]

Hello everyone,

i am using LabVIEW 2018 and a USB-6351 device to controle a stepper motor with a step/direction interface and to read an analog input. Right now i move the motor, then take a measurement, move the motor again, take another measurement etc.

This works but the start/stop of the motor adds some unwanted vibration to my system.

Is there a way to do both things (digitsl waveform for the motor, read analog input) simultaneously? If so, how do i do that?

Thanks in advance!

Create your two DAQmx task (DO, AI) and run them in parallel…

(You might look into syncing them, as explained in the example VIs found in the example finder.)

Thank you GerdW,

much easier than i thought. I tried to press it in to one task, which is obviously not how it works. Your solution works like a charm, looking into the syncing next.
