Annotation of standard text IEC 62541-6-ed.3.0 :

IEC 62541-6:2020 is available as IEC 62541-6:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62541-6:2020 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC TR 62541-2, the abstract service definitions specified in IEC 62541-4, the data structures defined in IEC 62541-5 and the physical network protocols that can be used to implement the OPC UA specification. 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) Encodings: • added JSON encoding for PubSub (non-reversible); • added JSON encoding for Client/Server (reversible); • added support for optional fields in structures; • added support for Unions. b) Transport mappings: • added WebSocket secure connection – WSS; • added support for reverse connectivity; • added support for session-less service invocation in HTTPS. c) Deprecated Transport (missing support on most platforms): • SOAP/HTTP with WS-SecureConversation (all encodings). d) Added mapping for JSON Web Token. e) Added support for Unions to NodeSet Schema. f) Added batch operations to add/delete nodes to/from NodeSet Schema. g) Added support for multi-dimensional arrays outside of Variants. h) Added binary representation for Decimal data types. i) Added mapping for an OAuth2 Authorization Framework.
IEC 62541-6:2020 est disponible sous forme de IEC 62541-6:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente.
LIEC 62541-6:2020 specifie les mappings de lArchitecture unifiee OPC (OPC UA) entre le modele de securite decrit dans lIEC TR 62541 2, les definitions de services abstraits specifiees dans lIEC 62541 4, les structures de donnees definies dans lIEC 62541 5 et les protocoles de reseaux physiques qui peuvent etre utilises pour mettre en ouvre la specification OPC UA. Cette troisieme edition annule et remplace la deuxieme edition parue en 2015. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) codages: • ajout du codage JSON pour PubSub (irreversible); • ajout du codage JSON pour le Client/Serveur (reversible); • ajout de la prise en charge des champs facultatifs dans les structures; • ajout de la prise en charge des Unions; b) mappings de transport: • ajout de la connexion securisee WebSocket (WSS); • ajout de la prise en charge de la connectivite inversee; • ajout de la prise en charge de linvocation de service sans session dans HTTPS; c) transport deconseille (absence de prise en charge sur la plupart des plateformes): • SOAP/HTTP avec WS-SecureConversation (tous les codages); d) ajout du mapping pour JSON Web Token; e) ajout de la prise en charge des Unions pour le Schema de NodeSet; f) ajout doperations par lots permettant dajouter/de supprimer des nouds au niveau du Schema de NodeSet; g) ajout de la prise en charge des matrices multidimensionnelles a lexterieur des Variantes; h) ajout dune representation binaire pour les types de donnees Decimaux; i) ajout du mapping pour le Cadre dautorisation OAuth2.
