OPC UA for Woodworking Machines – Part 1: Vertical Interface
7.18 WwAlarmConditionType ObjectType Definition
The WwAlarmConditionType represents a stateful message event from a module and is formally defined in Table 41. It is used to classify conditions to recognize acknowledgeable and confirmable event messages with the extensions of the interface IWwEventMessageType. As an enhancement to the more general conditions, an alarm contains an additional 0:ActiveState variable, which can be used to map the active state of an event message. In combination with this, the 0:EnabledState is used to control the usability of the condition. The behavior corresponds to the description of the 0:AlarmConditionType defined in OPC UA Part 9.
