Abstract:
The subject invention facilitates alert notification in an industrial environment. The systems and methods enable subscribing devices, such as hosts, to receive events and/or alarms associated with industrial controllers. In addition, a subscribed component can unsubscribe, refresh notification related information, and/or acknowledge a notification. The foregoing can be achieved through a set of objects (e.g., notify objects) that implement a notification and dynamic subscription process. A host system can instantiate an associated notify object, subscribe to an event, and be notified about the event. The invention enables multiple hosts to subscribe to the same event, allows each host to select events of interest, and enables the events to be queued if the events occur faster than can be sent. In one aspect of the invention, the systems and methods can be utilized with an event and alarm infrastructure that is applicable on a Control and Information Protocol (CIP).
