DAQmx Start Task (G Dataflow)

Version:
    Last Modified: February 6, 2017

    Transitions the task to the running state to begin the measurement or generation. Using this node is required for some applications and is optional for others.

    If you do not use this node, a measurement task starts automatically when DAQmx Read runs. The autostart input of DAQmx Write determines if a generation task starts automatically when DAQmx Write runs.

    If you do not use DAQmx Start Task and DAQmx Stop Task when you use DAQmx Read or DAQmx Write multiple times, such as in a loop, the task starts and stops repeatedly. Starting and stopping a task repeatedly reduces the performance of the application.

    error in

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

    task out

    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
