Configures the task to stop the acquisition when the device acquires all pretrigger samples, detects a rising or falling edge of a digital signal, and acquires all posttrigger samples.
task in is the name of the task that the operation applies.
source specifies the name of a terminal where there is a digital signal to use as the source of the trigger.
edge specifies on which edge of the digital signal the Reference Trigger occurs.
Trigger on a falling edge of the digital signal.
Trigger on a rising edge of the digital signal.
error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.
pretrigger samples per channel specifies the minimum number of samples to acquire per channel before recognizing the Reference Trigger. The number of post-trigger samples per channel is equal to number of samples per channel in the DAQmx Timing node minus pretrigger samples per channel.
task out is a reference to the task after this node runs.
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
