IEC 61804-3:2006

Function blocks (FB) for process control - Part 3: Electronic Device Description Language (EDDL)

IEC 61804-3:2006 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.

Blocs fonctionnels (FB) pour les procédés industriels - Partie 3: Langage de description électronique de produit (EDDL)

La CEI 61804-3:2006 spécifie la technologie de langage de description électronique d'appareil (Electronic Device Description Language: EDDL), qui permet en utilisant les outils d'ingénierie l'intégration de produit dans les systèmes tout au long du cycle de vie. Elle spécifie EDDL en tant que langage générique pour décrire les propriétés des composants système mettant en oeuvre des automatismes.
