DAQmx Trigger (Start » Analog Window) (G Dataflow)

Configures the task to start acquiring or generating samples when an analog signal enters or leaves a range you specify.

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

source

source is the name of a virtual channel or terminal where there is an analog signal to use as the source of the trigger.

For E Series devices, if you use a channel name, the channel must be the first channel in the task. The only terminal you can use for E Series devices is PFI0.

window top

window top is the upper limit of the window. Specify this value in the units of the measurement or generation.

window bottom

window bottom is the lower limit of the window. Specify this value in the units of the measurement or generation.

error in

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

when

when specifies whether the task starts measuring or generating samples, when the signal enters the window or when it leaves the window. Use window bottom and window top to specify the limits of the window.

Name Description
Entering Window

Start acquiring or generating samples when the signal enters the window.

Leaving Window

Start acquiring or generating samples when the signal leaves the window.

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
