DAQmx Create Timing Source (Control Loop From Task) (G Dataflow)

    Last Modified: February 6, 2017

    Creates a timing source that uses a combination of the sample clock and the specified sleep time to determine when to send ticks to a Timed Loop.

    You must create an analog input task that uses sample clock timing and wire that task to the task/channels in input of this node. Do not use the DAQmx Start Task node to start the task. The Timed Loop starts the task automatically. National Instruments recommends that you use this instance instead of the Signal From Task instance for best performance with Timed Loops.


    task in

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


    sleep time

    sleep time specifies in microseconds the amount of time the Timed Loop sleeps after each sample clock pulse. The default sleep time is 0. This input is ignored on all OSes other than Pharlap.


    error in

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


    timing source name

    timing source name is the name to assign to the timing source this node creates.


    task out

    task out is a reference to the task after this node or function completes execution.


    timing source out

    timing source out is the name of the timing source this node creates. Wire this output to the source input of the Input Node of a Timed Loop.

    If you specified a name for the timing source in the timing source name input, this output contains the same name. If you did not specify a name for the timing source, NI-DAQmx creates a name and sets this output to that name.


    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
