Launch Nested Actor (G Dataflow)

Version:
    Last Modified: April 27, 2020

    Launches an asynchronously running VI that performs tasks and handles Messages for the nested Actor. Use this VI to launch Actors that are dependent on one or more calling Actors. You must wire the caller Actor to the caller actor in input to call the nested Actor. This VI returns an error if the caller Actor is not launched already. Use the Launch Root Actor VI for launching an Actor without a caller.

    caller actor in

    The Actor that calls the nested Actor. caller actor in must already be launched before calling the nested Actor, or else this VI will return an error.

    datatype_icon

    nested actor

    Initial state of the Actor you want to launch.

    datatype_icon

    auto-stop

    Value that indicates whether the nested Actor stops when the calling Actor stops. The default value is True. If you set the value of this input to False, you must manually override the Stop Core VI on the caller Actor to specify stop behavior for the nested Actor.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    caller actor out

    Modified caller Actor. The caller Actor has a record of the nested Actor. The caller Actor uses the record of the nested Actor to automatically stop the nested Actor if auto-stop is set to True.

    datatype_icon

    nested actor's enqueuer

    Reference to the enqueuer. Use this reference to send Messages to the nested Actor.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
