DAQmx Control Task (G Dataflow)

Version:
    Last Modified: February 6, 2017

    Alters the state of a task according to the action you specify.

    If error in indicates that an error occurred previously, this node executes normally if action is unreserve or abort.

    task in

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

    datatype_icon

    action

    action specifies how to alter the task state.

    Name Description
    verify

    Verifies that all task parameters are valid for the hardware.

    reserve

    Reserves the hardware resources needed for the task. No other tasks can reserve these same resources.

    commit

    Programs the hardware as much as possible according to the task configuration.

    unreserve

    Releases all previously reserved resources.

    abort

    Aborts execution of the task. Aborting a task immediately terminates the currently active operation, such as a read or a write. Aborting a task puts the task into an unstable but recoverable state. To recover the task, use DAQmx Start to restart the task or use DAQmx Stop to reset the task without starting it.

    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
