This OPC UA ObjectType may be used for reporting simple information messages that do not represent an alarm. For instance some CNC systems offer the possibility to trigger messages out of the CNC part program for the purpose of tracking. This would be an example for using the CncMessageType.
As CncMessageType is derived from the OPC UA BaseEventType, it shall be used in most parts as specified in OPC 10000-5.
