You cannot use notifiers to communicate with VIs on other computers. For example, you cannot use notifiers to communicate across a network or the VI Server.

Unlike the Queue Operations functions, the Notifier Operations functions do not buffer sent messages. If no nodes are waiting on a message when it is sent, the data is lost if another message is sent. Notifiers behave like single-element, bounded, lossy queues.

Refer to the examples\general\notifier.llb for examples of using the Notifier Operations functions.
