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

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

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.

slope specifies on which slope of the signal to start acquiring or generating samples when the signal crosses level.

level specifies at what threshold to start acquiring or generating samples. Specify this value in the units of the measurement or generation. Use slope to specify on which slope to trigger at this threshold.

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

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.
