    task in

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

    datatype_icon

    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.

    datatype_icon

    slope

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

    Name Description
    Falling

    Start acquiring or generating samples when the signal crosses level on a falling slope.

    Rising

    Start acquiring or generating samples when the signal crosses level on a rising slope.

    datatype_icon

    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.

    datatype_icon

    error in

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

    datatype_icon

    task out

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

    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
