Abstract

L'invention concerne un système de mesure, de commande et de régulation programmable (19) destiné à des capteurs (17) ou des actuateurs (18) répartis. Ce système comporte une première interface de données (13) permettant son raccordement avec une interface de données standard (3) d'un ordinateur classique (1), et des organes permettant la programmation et/ou la commande des entrées et sorties (5, 9, 11) du système de mesure, de commande et de régulation (19) à l'aide de l'ordinateur en fonction de l'application. Pour plus d'efficacité, il est possible d'accéder à ces organes de programmation et/ou de commande des entrées et sorties par l'intermédiaire d'organes de commande et de programmation standard existant dans l'ordinateur. Pour encore plus d'efficacité, d'autres organes permettent un accès réciproque des organes d'exploitation de l'ordinateur et du système de mesure, de commande et de régulation. S'il existe par ailleurs une deuxième interface de données (25) présentant une fonctionnalité compatible au moins avec l'interface de données standard (3) de l'ordinateur (1) connectée avec la première interface de données (13), un autre système de mesure, de commande et de régulation programmable (21, 23) peut être raccordé en cascade par l'intermédiaire de cette première interface de données (13).
