DESCRIPTION

BS EN IEC 62541-9:2020


This standard BS EN IEC 62541-9:2020 OPC Unified Architecture is classified in these ICS categories:
  • 35.100.05 Multilayer applications
  • 25.040.40 Industrial process measurement and control
  • 35.100 Open systems interconnection (OSI)
IEC 62541-9:2020 is available as IEC 62541-9:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62541-9:2020 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. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added optional engineering units to the definition of RateOfChange alarms; b) to fulfill the IEC 62682 model, the following elements have been added: - AlarmConditionType States: Suppression, Silence, OutOfService, Latched; - AlarmConditionType Properties: OnDelay, OffDelay, FirstInGroup, ReAlarmTime; - New alarm types: DiscrepencyAlarm, DeviationAlarm, InstrumentDiagnosticAlarm, SystemDiagnosticAlarm. c) added Annex that specifies how the concepts of this OPC UA part maps to IEC 62682 and ISA 18.2; d) added new ConditionClasses: Safety, HighlyManaged, Statistical, Testing, Training; e) added CertificateExpiration AlarmType; f) added Alarm Metrics model.
