2.1.16 EventNotifier

EventNotifier special Attribute of a Node that signifies that a Client may subscribe to that particular Node to receive Notifications of Event occurrences
OPC-10000-3 – OPC Unified Architecture - Part 3: Address Space Model

4.7.1 General

AddressSpace . Objects and Views can be used to subscribe to Events . The EventNotifier Attribute of those Nodes identifies if the Node allows subscribing to Events . Clients subscribe to such Nodes ... Server that supports eventing shall expose at least one Node as EventNotifier . The Server Object defined in OPC 10000-5 is used for this purpose. Events generated by the Server
