Annotation of standard text IEC 62541-5-ed.3.0 :
IEC 62541-5:2020 is available as IEC 62541-5:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62541-5:2020 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardized Nodes of a Server’s AddressSpace. These Nodes are standardized types as well as standardized instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not expected that all Servers will provide all of these Nodes. 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 Annex F on User Authentication. Describes the Role Information Model that also allows configuration of Roles. b) Added new data types: "Union", "Decimal", "OptionSet", "DateString", "TimeString", "DurationString", NormalizedString", "DecimalString", and "AudioDataType". c) Added Method to request a state change in a Server. d) Added Method to set Subscription to persistent mode. e) Added Method to request resending of data from a Subscription. f) Added concept allowing to temporarily create a file to write to or read from a server in C.4. g) Added new Variable type to support Selection Lists. h) Added optional properties to FiniteStateMachineType to expose currently available states and transitions. i) Added UrisVersion Property to ServerType. This version information can be used for session-less service invocation. IEC 62541-5:2020 est disponible sous forme de IEC 62541-5:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente. IEC 62541-5:2020 definit le Modele dinformation de lArchitecture unifiee OPC. Le Modele dinformation decrit des Nouds normalises de lAddressSpace dun Serveur. Ces Nouds sont des types normalises ainsi que des instances normalisees utilises pour le diagnostic ou comme des points dentree a des Nouds specifiques au serveur. Ainsi, le Modele dinformation definit lAddressSpace dun Serveur OPC UA vide. Cependant, tous les Serveurs ne sont pas supposes fournir la totalite de ces Nouds. 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) ajout de lAnnexe F concernant lAuthentification des utilisateurs; description du Modele dinformation de role qui autorise egalement la configuration des Roles; b) ajout de nouveaux types de donnees: "Union", "Decimal", "OptionSet", "DateString", "TimeString", "DurationString", "NormalizedString", "DecimalString" et "AudioDataType"; c) ajout dune methode afin de demander un changement detat dans un Serveur; d) ajout dune methode afin de definir un Abonnement en mode persistant; e) ajout dune methode afin de demander le renvoi de donnees a partir dun Abonnement; f) ajout en C.4 dun concept permettant la creation temporaire dun fichier pour lecriture ou la lecture sur un serveur; g) ajout dun nouveau type de Variable afin de prendre en charge les Listes de selection; h) ajout de proprietes facultatives au FiniteStateMachineType afin de presenter les etats et transitions actuellement disponibles; i) ajout dune propriete UrisVersion au ServerType. Ces informations de version peuvent etre utilisees pour linvocation de services sans session.
