DAQmx Create Timing Source (Signal From Task) (G Dataflow)

Last Modified: September 18, 2017

Creates a timing source that uses the signal you specify to determine when to send ticks to a Timed Loop.

You must create a task that can generate the signal and wire that task to the task/channels in input of this node. Do not use the DAQmx Start Task node to start the task. The Timed Loop starts the task automatically.

task in

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

datatype_icon

signal

signal is the signal to use for the timing source.

Name Description
Change Detection Event

Send a tick to the Timed Loop each time the Change Detection Event occurs.

Counter Output Event

Send a tick to the Timed Loop each time the Counter Output Event occurs.

Sample Clock

Send a tick to the Timed Loop on each active edge of the Sample Clock.

Sample Complete Event

Send a tick to the Timed Loop each time the Sample Complete Event occurs.

error in

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

datatype_icon

timing source name

timing source name is the name to assign to the timing source this node creates.

datatype_icon

task out

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

datatype_icon

timing source out

timing source out is the name of the timing source this node creates. Wire this output to the source input of the Input Node of a Timed Loop.

If you specified a name for the timing source in the timing source name input, this output contains the same name. If you did not specify a name for the timing source, NI-DAQmx creates a name and sets this output to that name.

datatype_icon

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
