Disconnect (G Dataflow)

Version:
    Last Modified: September 16, 2017

    Disconnects routes as defined by the disconnection specification.

    In the event of an error, the call to Disconnect continues to try to disconnect everything specified by the disconnection specification string but reports the error upon completion.

    Programming Patterns

    Disconnect does not wait for debounce. Call Wait for Debounce to wait for debounce.

    connector_pane_image
    datatype_icon

    session in

    Handle that identifies your Switch Executive virtual device session previously allocated by Open Session.

    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

    disconnection specification

    String defining the channel disconnections to be made.

    If a route specified does not exist, an error condition occurs.

    datatype_icon

    session out

    Reference to your virtual device session to wire to the next node.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Disconnect Behavior of Multiconnected Routes

    If any of the routes specified by the disconnection specification input were originally connected using Multiconnect Routes (1) for multiconnect mode, the call to Disconnect reduces the reference count on the route by one. If the reference count reaches zero, it is disconnected.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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