The WSAlarmType provides two variables to inform about the current alarm and is formally defined in Table 17.
The WSAlarmCode can be used to pass an integer to the client and map it to a language-specific message. WSAlarmMessage contains the message as localizedText.
For the future it is planned to use OPC UA functionalities like Alarms and Conditions for this data point. As soon as this is available in the Weihenstephan Standards, this object definition will be obsolete.
