The EventType inherits the Properties of the BaseEventType.
- The mandatory Property EventId is a vendor-specific unique identification of the Event.
- The mandatory Property EventType reflects the type of Event, so either the NodeId of the IOLinkEventType or a subtype.
- The content of the Properties SourceNode, SourceName, Time, ReceiveTime, and Message is defined by its subtypes.
- The optional Property LocalTime shall not be provided.
- The Property Severity reflects the mode of IO-Link events. The IOLinkEventType or subtypes shall only be used for “Notification” and the severity shall be “200”. The Property IOLinkEventCode is defined by the subtypes of the EventType.
