OPC Unified Architecture -- Part 5: Information Model (IEC 62541-5:2015)

This part of IEC 62541 defines the Information Model of the OPC Unified Architecture. The
Information Model describes standardised Nodes of a Server’s AddressSpace. These Nodes
are standardised types as well as standardised 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.

OPC unified architecture - Part 5: Information Model (IEC 62541-5:2015)

Architecture unifiée OPC - Partie 5: Modèle d'informations (IEC 62541-5:2015)

L'IEC 62541-5:2015 définit le Modèle d'informations de l'Architecture unifiée OPC. Le Modèle d'informations décrit des Noeuds (Nodes) normalisés d'un Espace d'Adresses (AddressSpace) d'un Serveur (Server). Ces Noeuds sont des types normalisés ainsi que des instances normalisées utilisés pour le diagnostic ou comme des points d'entrée à des Noeuds spécifiques au serveur. Cette deuxième édition annule et remplace la première édition parue en 2011. Elle constitue une révision technique. Cette édition inclut les modifications suivantes:
- ProgressEventType identifiant l'avancement d'une opération telle que l'appel d'un service;
- DataType appelé BitFieldMaskDataType;
- Propriété SamplingRateCount supprimée dans le ServerDiagnosticSummaryDataType;
- Ajout de la propriété "EffectiveTransitionTime" au TransitionVariableType;
- Introduction du VariableType OptionSetType;
- Ajout d'un nouveau EventType appelé SystemStatusChangeEventType;
- Ajout de propriétés à ServerCapabilitiesType, de même qu'ajout d'un objet pour les limites de fonctionnement. Ajout du type OperationLimitsType;
- Ajout de SecureChannelId à AuditActivateSession-EventType;
- Ajout d'une Annexe C normative définissant le FileType et les Méthodes utilisés pour le transfert de fichiers;
- Ajout d'une Méthode GetMonitoredItems à ServerType;
- Suppression du concept de ModelParent;
- Ajout de métadonnées pour les espaces de noms dans ServerType. Ajout des représentations pour les ModellingRules OptionalPlaceholder et MandatoryPlaceholder;
- Ajout des nouveaux types NonTransparentNetworkRedundancyType, NetworkGroupDataType et EndpointUrlListDataType afin de gérer la redondance HotAndMiorrored. Ajout d'une description supplémentaire de la redondance et mise à jour de l'énumération RedundancySupport en 12.5.

Enotna arhitektura OPC - 5. del: Informacijski model (IEC 62541-5:2015)

Ta del standarda IEC 62541 določa informacijski model enotne arhitekture OPC. Informacijski model opisuje standardizirana vozlišča strežnikovega naslovnega prostora. Ta vozlišča so standardizirane vrste in primerki, ki se uporabljajo za diagnostiko ali kot vstopne točke v strežniška vozlišča. Informacijski model tako določi naslovni prostor praznega strežnika enotne arhitekture OPC. Vendar se ne pričakuje, da bodo vsi strežniki zagotovili vsa vozlišča.
