DAQmx Export Signal (Most Signals) (G Dataflow)

Last Modified: January 11, 2018

Routes a control signal to the terminal you specify. The output terminal can reside on the device that generates the control signal or on a different device. You can use this node to share clocks and triggers among multiple tasks and devices. The routes this node creates are task-based routes.


task in

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



signal is the name of the trigger, clock, or event to export.

Name Description
10 MHz Reference Clock

Output of an oscillator that you can use to synchronize multiple devices.

20Mhz Timebase Clock

Output of an oscillator that is the onboard source of the Master Timebase. Other timebases are derived from this clock.

Advance Complete Event

Signal a switch product generates after it both executes the command(s) in a scan list entry and waits for the settling time to elapse.

Advance Trigger

Trigger that moves a switch to the next entry in a scan list.

AI Convert Clock

Clock that causes an analog-to-digital conversion on a multiplexed device. One conversion corresponds to a single sample from one channel.

AI Hold Complete Event

Signal a multiplexed device generates when the device latches analog input data (the ADC enters "hold" mode), and it is safe for any external switching hardware to remove the signal, and replace it with the next signal. This event does not indicate the completion of the actual analog-to-digital conversion.

Change Detection Event

Signal a static DIO device generates when the device detects a rising or falling edge on any of the lines or ports you selected when you configured change detection timing.

Counter Output Event

Signal a counter generates. Each time the counter reaches terminal count, this signal toggles or pulses. This also applies to counter output tasks.

Reference Trigger

Trigger that establishes the reference point between pretrigger and posttrigger samples.

Sample Clock

Clock the device uses to time each sample.

Start Trigger

Trigger that begins a measurement or generation.

Watchdog Timer Expired Event

Signal a static DIO device generates when the watchdog timer expires.


output terminal

output terminal is the destination of the exported signal. A DAQmx terminal constant lists all terminals on installed devices. You can also specify a string containing a comma-delimited list of terminal names.


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 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
