5.4.3 SINUMERIK Alarm object
5.4.3.1 Description
Every variable or object in the address space of an OPC UA Server is called a node. Every
node has a server unique node id, its symbolic name, addressing information inside the
address model and some other attributes.
Events are by themselves not visible as nodes in the address space. They can only be received
via objects. Not all objects can signal events. Whether an object can signal events is specified
at the object by the EventNotifier attribute. Only objects where this attribute has been set can
be specified in the Event Monitored Item and received in Clients Events.
The Server Object serves as root notifier, that is, its EventNotifier Attribute shall be set providing
Events. However Server object will not be allowed to subscribe for the Events. Only the
"Sinumerik" Object node is accessible and can subscribe to the events.
5.4.3.2 OPC UA event messages and alarms

are available below the ConditionType. The Application-specific event types such as
CncAlarmType can be derived. The CncAlarmType extends the DiscreteAlarmType.
