Abstract

Système de transmission de données entre stations connectées par un bus commun dans lequel la priorité d'accès au bus est déterminé par les stations elle-mêmes. Chaque station comprend un compteur 21 restauré à chaque période de temps déterminée par les signaux de synchronisation des stations reçus en 8, et dont le contenu est comparé par le comparateur 24 au contenu du registre 23 qui est fonction de la priorité de la station. En cas de comparaison favorable, la station a la priorité d'accès au bus 6 et un signal d'inhibition 9 est transmis aux autres stations pour les empêcher d'obtenir l'accès au bus pendant la période de temps qui suit Un tel système améliore la souplesse des transmissions de données entre stations.
