Abstract

L'invention se rapporte à un dispositif de recueil d'informations collectives sur un bus série. Dans chaque organe périphérique relié à la branche de retour BR d'un bus série rebouclé raccordé à une unité centrale, on dispose un circuit de formation de signal de déclenchement 1 relié à l'entrée d'horloge d'un registre à décalage REG dont une cellule R4 est reliée à la mémoire de l'organe considéré, dont toutes les autres cellules sont reliées à un niveau logique inactif, et dont la sortie est reliée à une porte ET 4 validée par le signal de déclenchement dont chaque période correspond à un emplacement du mot série de réponse. Application : interrogation par une unité centrale des mémoires des périphériques coopérant avec elle.
