This OPC UA ObjectType represents a CNC Interface. CncInterfaceType is the entry point to the CNC data interface. It is mainly used for structuring the interface. But additionally this ObjectType holds Properties characterizing this interface (Version, VendorName etc.), as well as References to the specified EventTypes. There are two different types of events generated by an instance of CncInterfaceType: events of type CncMessageType and of type CncAlarmType.
Events of type CncAlarmType are used to provide CNC error messages.
Events of type CncMessageType are used to provide messages that are not an alarm but a non-critical information, e.g. a user created message out of the CNC part program.
CncInterfaceType is formally defined in Table 7.
