OPC Unified Architecture - Part 9: Alarms and conditions (IEC 62541-9:2020)
This part of IEC 62541 specifies the representation of Alarms and Conditions in the OPC
Unified Architecture. Included is the Information Model representation of Alarms and
Conditions in the OPC UA address space. Other aspects of alarm systems such as alarm
philosophy, life cycle, alarm response times, alarm types and many other details are captured
in documents such as IEC 62682 and ISA 18.2. The Alarms and Conditions Information Model
in this specification is designed in accordance with IEC 62682 and ISA 18.2.

IEC 62541-9:2020 est disponible sous forme de IEC 62541-9:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
a) des unités techniques facultatives ont été ajoutées à la définition des alarmes RateOfChange;
b) afin de respecter le modèle IEC 62682, les éléments suivants ont été ajoutés:
- états d'AlarmConditionType: Suppression, Silence, OutOfService, Latched;
- Propriétés d'AlarmConditionType: OnDelay, OffDelay, FirstInGroup, ReAlarmTime;
- nouveaux types d'alarmes: DiscrepencyAlarm, DeviationAlarm, InstrumentDiagnosticAlarm, SystemDiagnosticAlarm;
c) ajout d'une annexe qui spécifie la manière dont les concepts de cette partie d'OPC UA assurent la correspondance avec l'IEC 62682 et l'ISA 18.2;
d) nouvelles ConditionClasses ajoutées: Safety, HighlyManaged, Statistical, Testing, Training;
e) ajout de l'AlarmType CertificateExpiration;
f) ajout d'un modèle de Mesures d'Alarme.
