(Main)Field device integration (FDI®) - Part 8: EDD to OPC-UA Mapping
Field device integration (FDI®) - Part 8: EDD to OPC-UA Mapping
IEC 62769-8:2023 specifies how the internal view of a device model represented by the EDD can be transferred into an external view as an OPC-UA information model by mapping EDD constructs to OPC-UA objects.
Feldgeräteintegration (FDI®) - Teil 8: EDD zu OPC-UA Mapping
Intégration des appareils de terrain (FDI®) - Partie 8: Mapping de l'EDD avec l'OPC-UA
L'IEC 62769-8:2023 spécifie comment la vue interne d'un modèle d'appareil représentée par l'EDD peut être transférée dans une vue externe sous forme de modèle d'information OPC-UA en mappant les constructions EDD avec des objets OPC-UA.
Integracija procesne naprave (FDI®) - 8. del: Preslikava EDD v OPC-UA (IEC 62769-8:2023)
Standard IEC 62769-8:2023 določa, kako je mogoče notranji pogled modela naprave, ki ga predstavlja EDD, prenesti v zunanji pogled kot informacijski model OPC-UA s preslikavo konstruktov EDD v objekte OPC-UA.
