    • 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).
    • 本发明在工业环境中促进警报通知。 系统和方法使诸如主机之类的订阅设备能够接收与工业控制器相关联的事件和/或警报。 此外,订阅的组件可以取消订阅,刷新通知相关信息和/或确认通知。 可以通过实现通知和动态订阅过程的一组对象(例如,通知对象)来实现上述内容。 主机系统可以实例化关联的通知对象,订阅事件,并通知事件。 本发明使得多个主机能够订阅相同的事件,允许每个主机选择感兴趣的事件,并且如果事件发生得比可发送的更快,则允许事件排队。 在本发明的一个方面,系统和方法可以与适用于控制和信息协议(CIP)的事件和报警基础设施一起使用。
