DAQmx Timing (Use Waveform) (G Dataflow)

Last Modified: July 19, 2019

Uses the dt component of the waveform input to determine the Sample Clock rate.

dt is the time in seconds between samples. If sample mode is Finite Samples, NI-DAQmx generates the number of samples in the waveform. This node does not actually generate any samples. You must wire the same waveform to the DAQmx Write node to generate the samples.


task in

task in is the name of the task that the operation applies.



waveform is the waveform to use for timing.


error in

error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.


sample mode

sample mode specifies if the task acquires, or generates samples continuously, or if it acquires or generates a finite number of samples.

Name Description
Continuous Samples

Acquire or generate samples until DAQmx Stop Task runs.

Finite Samples

Acquire or generate a finite number of samples.

Hardware Timed Single Point

Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types.


task out

task out is a reference to the task after this node runs.


error out

error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.

Where This Node Can Run:

Desktop OS: Windows

FPGA: LabVIEW NXG does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
