DAQmx Wait for Valid Timestamp (G Dataflow)

Last Modified: May 7, 2018

Wait until the specified timestamp has a value.

Use this node to ensure the timestamp has a valid value to prevent an error when querying a timestamp value.


task in

task in specifies the task to which to add the virtual channels this node creates. If you do not specify a task, NI-DAQmx creates a task for you, and adds the virtual channels this node creates to that task.



timestamp specifies the timestamp type to wait on.

Name Description
Start Trigger

Reference Trigger

Arm Start Trigger

First Sample

First Sample Timestamp.


timeout (sec)

timeout (sec) specifies the maximum amount of time in seconds to wait for a valid timestamp. This node returns an error if the time elapses. The default is 10. If you set timeout (sec) to -1, the node waits indefinitely.

If you set timeout (sec) to 0, the node checks once and returns an error if the measurement or generation is not done.


error in

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


task out

task out is a reference to the task after this node or function completes execution.


timestamp value

timestamp valueindicates the value of the timestamp.


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
