This standard Object Node is the browse entry point for EventType Nodes. Figure 7 illustrates the structure beneath this Node showing some of the standard EventTypes defined in Clause 6. Only Organizes References are used to relate Objects and ObjectTypes to the “EventTypes” standard Object. The “EventTypes” Object shall not reference any other NodeClasses.

Figure 7 – EventTypes Organization

The intention of the “EventTypes” Object is that all EventTypes of the Server are either directly or indirectly accessible browsing HierarchicalReferences starting from this Node. It is required that the Server expose all its EventTypes, so a client can usefully subscribe to Events.

The “EventTypes” Object is formally defined in Table 87.
