IEC 61804-4-ed.2.0

IEC 61804-4:2020 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.

This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition was developed by merging material from multiple variants of existing EDDL specifications including those from FieldComm Group (Foundation™ Fieldbus , HART® ), PROFIBUS™ Nutzerorganisation e.V. (PNO), and ISA100_Wireless™ Compliance Institute (ISA100 WCI). When a profile deviation exists, it is now indicated in the context where the related deviation is found. As a result, the formatting and numbering of this edition may be different from any of the individual specifications from which this edition was derived. This edition includes the following significant technical changes with respect to the previous edition: • communication profiles ISA100 and GPE were added; • description of rules for optimized-column-width layout have been added; • description of the concatenation of labels and help was added; • color banding for meter type charts was added.

IEC 61804-4:2020 definit linterpretation EDD pour les applications EDD et les EDD afin dassurer linteroperabilite EDD. Le present document est destine a garantir que les developpeurs dappareils de terrain utilisent systematiquement les constructions EDDL et que les applications EDD aient la meme interpretation des EDD. Il complete la specification EDDL pour promouvoir linteroperabilite de lapplication EDDL et ameliorer la portabilite EDD entre les applications EDDL.

Cette deuxieme edition annule et remplace la premiere edition parue en 2015. Cette edition constitue une revision technique. Cette edition a ete elaboree en fusionnant le contenu de plusieurs variantes des specifications de lEDDL existantes, y compris celles du FieldComm Group (Foundation™ Fieldbus , HART® ), du PROFIBUS™ Nutzerorganisation e.V. (PNO), et de lISA100_Wireless™ Compliance Institute (ISA100 WCI). Lorsquune deviation de profil existe, cela est desormais indique dans le contexte ou la deviation en question a ete identifiee. Par consequent, le formatage et la numerotation de la presente edition peuvent differer des specifications individuelles desquelles elle est issue. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: • ajout des profils de communication ISA100 et GPE; • ajout de la description des regles pour la disposition de largeur optimale des colonnes; • ajout de la description de la concatenation des libelles et des aides; • ajout de bandes de couleurs sur les diagrammes de type instrument de mesure.
