Use the '''Notifier Operations''' functions to suspend the execution of a block diagram until you receive data from another section of the block diagram or from another VI running in the same application instance.

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[[Functions Palette/Programming/Synchronization/Queue Operations|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.

When using a Notifier Operation function in a [[Functions Palette/Programming/Structures/While Loop|While Loop]], the stop condition should be connected to the execution of the function.
