    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.

    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

    high time

    high time is the amount of time the pulse is high.

    datatype_icon

    low time

    low time is the amount of time the pulse is low.

    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.
