OPC unified architecture - Part 5: Information model (IEC 62541-5:2011)

This part of IEC 62541 defines the Information Model of the OPC Unified Architecture (OPC
UA). 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 - Teil 5: Informationsmodell (IEC 62541-5:2011)

Architecture unifiée OPC - Partie 5: Modèle d'information (CEI 62541-5:2011)

La CEI 62541-5:2011 définit le modèle d'information d'OPC Unified Architecture (OPC UA). Le Modèle d'information décrit des Nodes (c'est-à-dire des noeuds) normalisés d'un AddressSpace (c'est-à-dire espace d'adresse) d'un serveur. Ces Noeuds sont des types normalisés ainsi que des instances normalisées pour le diagnostic ou comme des points d'entrée à des Nodes spécifiques de serveur. Ainsi, le Modèle d'information définit l'Espace d'adresse d'un serveur OPC UA vide. Il n'est cependant pas demandé que tous les serveurs fournissent la totalité des Nodes.

Poenotena arhitektura OPC - 5. del: Informacijski model (IEC 62541-5:2011)

Ta del standarda IEC 62541 določa informacijski model poenotene arhitekture OPC (OPC
UA). 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 poenotene arhitekture OPC. Vendar se ne pričakuje, da bodo vsi strežniki zagotovili vsa vozlišča.
