OPC-40502 – OPC UA for Computerized Numerical Control (CNC) Systems - for CNC Systems: OPC UA Information Model

6.10.1 General

must be used for reporting alarms of the CNC system. CncAlarmType must derived from DiscreteAlarmType . The CncAlarmType extends the DiscreteAlarmType as followed: HelpSource : To provide additional information to the alarm ... information fragments provided by this parameter. As CncAlarmType is derived from the OPC UA DiscreteAlarmType , it shall be used in most parts as specified in OPC 10000-5 . However
