Information about Events (Notification) is not mapped to additional EventTypes, but the IOLinkIODDDeviceEventType is used.

When an IO-Link Device sends a Notification, and the server manages the IODD for the IO-Link Device, an Event of the IOLinkIODDDeviceEventType is generated according to the EventType definition.

Information about Alarms (Warning and Error) is not mapped to additional EventTypes, but the IOLinkIODDDeviceAlarmType is used. If the OPC UA server supports Alarm Objects represented in the AddressSpace, the server may provide the Alarms Object on the ObjectType and provide all possible Alarms as Objects based on the IODD.

When an IO-Link Device sends a Warning or Error, and the server manages the IODD for the IO-Link Device, an Event of the IOLinkIODDDeviceAlarmType is generated according to the EventType definition.
