Function Blocks (FB) for process control and Electronic Device Description Language (EDDL) - Part 3: EDDL syntax and semantics

IEC 61804-3:2015 specifies the Electronic Device Description Language (EDDL) technology, which enables the integration of real product details using the tools of the engineering life cycle. It specifies EDDL as a generic language for describing the properties of automation system components. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Builtins and their profiles removed and relocated into IEC 61804-5. The following extensions are integrated in the EDDL specification to meet FDI requirements: - new contructs BLOB, PLUGIN; - component construct for communication server requirements (additional attributes); - extension of the class attribute; - new attributes PRIVATE, VISIBILITY, WRITE_MODE.

Blocs Fonctionnels (FB) pour les procédés industriels et le Langage de Description Electronique de Produit (EDDL) - Partie 3: Sémantique et syntaxe EDDL

L'IEC 61804-3:2015 spécifie la technologie de langage de description électronique de produit (EDDL), qui permet en utilisant les outils d'ingénierie l'intégration des détails du produit réel dans les systèmes tout au long du cycle de vie. Elle spécifie l'EDDL en tant que langage générique pour décrire les propriétés des composants système mettant en oeuvre des automatismes. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: Les Builtins et leurs profils ont été supprimés et déplacés dans la norme IEC 61804-5. Les extensions suivantes sont intégrées à la spécification EDDL pour satisfaire aux exigences FDI: - nouvelles constructions de BLOB, PLUGIN; - construction de composant pour les exigences de serveur de communication (attributs supplémentaires); - extension de l'attribut classe; - nouveaux attributs PRIVATE, VISIBILITY, WRITE_MODE.

Funkcijski bloki (FB) za nadzor procesov in opisni jezik za elektronske naprave (EDDL) - 3. del: Sintaksa in semantika EDDL (IEC 61804-3:2015)

Ta del standarda IEC 61804 določa tehnologijo opisnega jezika za elektronske naprave (EDDL), ki omogoča integracijo dejanskih podrobnosti izdelka z uporabo orodij življenjskega cikla inženiringa.
Ta del standarda IEC 61804 določa opisni jezik za elektronske naprave kot splošni jezik za opisovanje lastnosti komponent avtomatiziranih sistemov. Opisni jezik za elektronske naprave lahko opisuje:
• parametre naprav in njihove odvisnosti;
• funkcije naprav, npr. način simulacije, umerjanje;
• grafične predstavitve, npr. menije;
• medsebojno vplivanje krmilnih naprav;
• grafične predstavitve:
– izboljšan uporabniški vmesnik,
– grafični sistem;
• obstojno shrambo podatkov.
Opisni jezik za elektronske naprave se uporablja za ustvarjanje opisov za elektronske naprave (EDD), npr. fizične naprave, splošno uporabljane profile ali knjižnice. Ta opis za elektronske naprave se uporablja z ustreznimi orodji za generiranje razlagalne kode za podporo ravnanju s parametri ter upravljanje in nadzor komponent avtomatiziranih sistemov, kot so oddaljeni I/O, krmilniki, senzorji in programirljivi krmilniki. Uvedba orodja ni zajeta v tem standardu. Ta del standarda IEC 61804 določa semantično in leksikalno strukturo na način, ki je neodvisen od sintakse. V dodatku A je opredeljena specifična sintaksa, vendar je semantični model mogoče uporabljati
z različnimi sintaksami.
