IEC 61800-7-304:2007

Adjustable speed electrical power drive systems - Part 7-304: Generic interface and use of profiles for power drive systems - Mapping of profile type 4 to network technologies

IEC 61800-7-304:2007 specifies profiles for Power Drive Systems (PDS) and their mapping to existing communication systems by use of a generic interface model. It also specifies the mapping of the profile type 4 (SERCOS) specified in IEC 61800-7-204 onto different network technologies: SERCOS I / II, SERCOS III, EtherCAT.

Entraînements électriques de puissance à vitesse variable - Partie 7-304: Interface générique et utilisation de profils pour les entraînements électriques de puissance - Mise en correspondance du profil de type 4 avec les technologies de réseaux

La CEI 61800-7-304:2007 spécifie les profils dédiés aux entraînements électriques de puissance (PDS) et leur mise en correspondance avec les systèmes de communication existants grâce à un modèle d'interface générique. Il spécifie aussi la mise en correspondance du profil de type 4 (SERCOS), décrit dans la CEI 61800-7-204, avec les différentes technologies de réseaux: SERCOS I / II, SERCOS III, EtherCAT.
