Disconnect (G Dataflow)

Last Modified: September 26, 2018

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
