IEC 62769-5:2021

Field Device Integration (FDI) - Part 5: Information Model

IEC 62769-5:2021 defines the FDI Information Model. One of the main tasks of the Information Model is to reflect the topology of the automation system. Therefore, it represents the devices of the automation system as well as the connecting communication networks including their properties, relationships, and the operations that can be performed on them. The types in the AddressSpace of the FDI Server constitute a catalogue, which is built from FDI Packages. The fundamental types for the FDI Information Model are well defined in OPC UA for Devices (IEC 62541-100). The FDI Information Model specifies extensions for a few special cases and otherwise explains how these types are used and how the contents are built from elements of DevicePackages. The overall FDI architecture is illustrated in Figure 1. The architectural components that are within the scope of this document have been highlighted in this illustration.

Intégration des appareils de terrain (FDI) - Partie 5: Modèle d'Information

L’IEC 62769-5:2021 définit le Modèle d'Information FDI. L'un des principaux objectifs du Modèle d'Information est de refléter la topologie du système d'automatisation. Par conséquent, il représente les appareils du système d'automatisation ainsi que les réseaux de communication connectés, y compris leurs propriétés, leurs relations et les opérations dont ils peuvent faire l'objet. Les types présents dans l'AddressSpace (Espace d'adressage) du Serveur FDI constituent un catalogue, construit à partir des FDI Packages (Paquetages FDI). Les types fondamentaux pour le Modèle d'Information FDI sont définis dans l'OPC UA pour les Appareils (IEC 62541-100). Le Modèle d'Information FDI spécifie des extensions pour quelques cas spéciaux et explique la façon dont ces types sont utilisés et dont les contenus sont construits à partir des éléments de DevicePackages. L'architecture FDI complète est représentée à la Figure 1. Les composants architecturaux qui relèvent du domaine d'application du présent document ont été mis en évidence dans cette représentation.
