Abstract

L'invention concerne un automate programmable. L'appareil comprend une unité centrale 1 traitant les signaux d'un comparateur 3 de l'état de capteurs 2 à des conditions logiques stockées dans une mémoire condition 4 pour exécuter sur des organes de commande 1 des instructions stockées sur un support mémoire 6. Les mémoires condition 4 et de commande 6 sont des mémoires mortes EPROM. L'invention s'applique aux automates programmables.
