Abstract

L'invention concerne un compteur électronique avec une mémoire rémanente. Il comporte un dispositif de détection d'interruption d'alimentation qui commande le transfert du contenu du compteur vers la mémoire rémanente, et un dispositif de détection de retour d'alimentation qui commande le transfert du contenu de la mémoire rémanente vers le compteur. L'invention s'applique notamment au compteur d'opérations exécutés par les dispositifs industriels.
