The ScaleEventType and the ScaleAlarmType both contain the NotificationId to identify the event or alarm. Annex C contains all events and alarms defined in this specification. If possible, scales must use these events/alarms. The NotificationId contains the properties EnumValue and ValueAsText (inherit from the MultiStateValueDiscreteType) which contain the value and a short 0:String of the available NotificationIds. This can be a subset of all NotificationIds descripted in Annex C. Additional NotificationIds can be defined in a vendor-specific way. The value of the EnumValue for vendor-specific NotificationIds must be greater than 5000. Each vendor can use an additional ID (vendor-specific NotificationId) to transmit the vendor-specific ID.

The ScaleEventType is a subtype of the BaseEventType, which it extends with some Properties. It should be used for all Events that are relevant to the weighing technology.

AuxParameters is an additional text of the event. In the text it is used for the placeholders in the message to the alarm.

HelpSource is a source for additional help information.

NotificationCategory provides the category of the notification. It is used to distinguish if the message is representing an internal event, an information, a dialogue message, an error, a warning, a state or an acknowledgement. Annex C contains all NotificationCategory defined in this specification.

NotificationId provides a unique identifier for the event. Annex C contains all IDs defined in this specification.

VendorNotificationId is a unique vendor-specific identifier for the event.

The ScaleAlarmType is a subtype of the AcknowledgeableConditionType and extends it with some Properties. It should be used for all alarms relevant for the weighing technology.

It is used to distinguish if the message is representing an internal event, an information, a dialogue message, an error, a warning, a state or an acknowledgement. Annex D contains all options for NotificationCategory defined in this specification.

NotificationId provides a unique identifier for the alarm. Annex D contains all IDs defined in this specification.

VendorNotificationId is a unique vendor-specific identifier for the event.
