DAQmx Timing (Implicit) (G Dataflow)

Version:
    Last Modified: February 6, 2017

    Sets only the number of samples to acquire or generate without specifying timing.

    Typically, you should use this instance when the task does not require sample timing, such as tasks that use counters for buffered frequency measurement, buffered period measurement, or pulse train generation. For finite counter output tasks, samples per channel is the number of pulses to generate.

    task in

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

    datatype_icon

    error in

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

    datatype_icon

    sample mode

    sample mode specifies if the task acquires, or generates samples continuously, or if it acquires or generates a finite number of samples.

    Name Description
    Continuous Samples

    Acquire or generate samples until DAQmx Stop Task runs.

    Finite Samples

    Acquire or generate a finite number of samples.

    Hardware Timed Single Point

    Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types.

    datatype_icon

    samples per channel

    samples per channel specifies the number of samples to acquire, or generate for each channel in the task, if sample mode is Finite Samples. If sample mode is Continuous Samples, NI-DAQmx uses this value to determine the buffer size. This node returns an error if the specified value is negative.

    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.

    Desktop OS: Windows
