MonitoredItem service set

Collaboration diagram for MonitoredItem service set:

Detailed Description

Subscribe to data and events.

Note the difference between Subscriptions and MonitoredItems. Subscriptions are used to report back notifications. Monitored items are used to generate notifications. Every monitored item is attached to exactly one subscription. And a subscription can contain many monitored items.

Monitored items can also be registered locally (server-side). Notifications are then forwarded to a user-defined callback instead of a remote client.
