OPC Unified Architecture - Part 11: Historical Access

IEC 62541-11:2020 is available as IEC 62541-11:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62541-11:2020 is part of the OPC Unified Architecture standard series and defines the information model associated with Historical Access (HA). It particularly includes additional and complementary descriptions of the NodeClasses and Attributes needed for Historical Access, additional standard Properties, and other information and behaviour. The complete AddressSpace Model including all NodeClasses and Attributes is specified in IEC 62541-3. The predefined Information Model is defined in IEC 62541-5. The Services to detect and access historical data and events, and description of the ExtensibleParameter types are specified in IEC 62541-4. This document includes functionality to compute and return Aggregates like minimum, maximum, average etc. The Information Model and the concrete working of Aggregates are defined in IEC 62541-13. 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) a new method for determining the first historical point has been added; b) added clarifications on how to add, insert, modify, and delete annotations.

Architecture unifiée OPC - Partie 11: Accès à l'Historique

IEC 62541-11:2020 est disponible sous forme de IEC 62541-11:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62541-11:2020 fait partie d'une série de normes d'Architecture Unifiée OPC globale et définit le Modèle d'Information associé à l'Accès à l'Historique (HA). Elle inclut en particulier des descriptions supplémentaires et complémentaires des NodeClasses et des Attributs nécessaires pour l'Accès à l'Historique, des Propriétés normalisées supplémentaires et d'autres informations et comportements. Le Modèle complet de l'AddressSpace comprenant toutes les NodeClasses et tous les Attributs est présenté dans l'IEC 62541-3. Le Modèle d'Information prédéfini est présenté dans l'IEC 62541-5. Les Services permettant de détecter et d'accéder aux données et événements historiques, ainsi qu'une description des types ExtensibleParameter, sont spécifiés dans l'IEC 62541-4. Le présent document inclut une fonctionnalité permettant de calculer et de renvoyer des Agrégats (minimum, maximum, moyenne, etc.). Le Modèle d'information et la fonction concrète des Agrégats sont définis dans l'IEC 62541-13. Cette troisième édition annule et remplace la deuxième édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout d'une nouvelle procédure de détermination de la première référence historique; b) ajout d'explications complémentaires sur les procédures d'ajout, d'insertion, de modification et de suppression d'annotations.
