Devices and integration in enterprise systems - Function blocks (FB) for process control and electronic device description language (EDDL) - Part 4: EDD interpretation (IEC 61804-4:2020)

This part of IEC 61804 specifies EDD interpretation for EDD applications and EDDs to support
EDD interoperability. This document is intended to ensure that field device developers use the
EDDL constructs consistently and that the EDD applications have the same interpretations of
the EDD. It supplements the EDDL specification to promote EDDL application interoperability
and improve EDD portability between EDDL applications.

Blocs fonctionnels (FB) pour les procédés industriels et le langage de description électronique de produit (EDDL) - Partie 4: Interprétation EDD (IEC 61804-4:2020)

IEC 61804-4:2020 définit l'interprétation EDD pour les applications EDD et les EDD afin d'assurer l'interopérabilité EDD. Le présent document est destiné à garantir que les développeurs d'appareils de terrain utilisent systématiquement les constructions EDDL et que les applications EDD aient la même interprétation des EDD. Il complète la spécification EDDL pour promouvoir l'interopérabilité de l'application EDDL et améliorer la portabilité EDD entre les applications EDDL. Cette deuxième édition annule et remplace la première édition parue en 2015. Cette édition constitue une révision technique. Cette édition a été élaborée en fusionnant le contenu de plusieurs variantes des spécifications de l'EDDL existantes, y compris celles du FieldComm Group (Foundation™ Fieldbus , HART® ), du PROFIBUS™ Nutzerorganisation e.V. (PNO), et de l'ISA100_Wireless™ Compliance Institute (ISA100 WCI). Lorsqu'une déviation de profil existe, cela est désormais indiqué dans le contexte où la déviation en question a été identifiée. Par conséquent, le formatage et la numérotation de la présente édition peuvent différer des spécifications individuelles desquelles elle est issue. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: • ajout des profils de communication ISA100 et GPE; • ajout de la description des règles pour la disposition de largeur optimale des colonnes; • ajout de la description de la concaténation des libellés et des aides; • ajout de bandes de couleurs sur les diagrammes de type instrument de mesure.
