DAQmx Read (Single Sample) (G Dataflow)

Version:
    Last Modified: February 6, 2017

    Reads a 32-bit unsigned integer sample from a counter task. Use an instance that reads 32-bit unsigned integers when NI-DAQmx returns counter samples unscaled, such as for event counting.

    error in

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

    timeout

    timeout specifies the amount of time in seconds to wait for samples to become available. If the time elapses, the node returns an error and any samples read before the timeout elapsed. The default timeout is 10 seconds. If you set timeout to -1, the node waits indefinitely.

    If you set timeout to 0, the node tries once to read the requested samples and returns an error if it is unable to.

    task out

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

    error out

    error out contains error information. This output provides standard error out functionality.
