Title (EN) SUPERVISORY CONTROL SYSTEM HAVING IMPROVED MEMORY MANAGEMENT
(FR) SYSTEME DE COMMANDE DE SURVEILLANCE A GESTION DE MEMOIRE AMELIOREE
Abstract:
(EN) An alarm system includes a plurality of slave controllers (11), each controlling a device such as a fire detector, window closure switch, temperature sensor, or alarm bell. The slave controllers (11) communicate through communication lines (12) and (13) with a master controller (10) which, for example, has the capability of polling the slave controllers (11) to determine their status or the status of the various devices they control.
(FR) Un système d'alarme comprend une pluralité de contrôleurs asservis (11), chacun contrôlant un dispositif tel qu'un détecteur d'incendie, un interrupteur de fermeture de fenêtre, un capteur de température ou un avertisseur d'alarme. Les contrôleurs asservis (11) communiquent par l'intermédiaire de lignes de communication (12 et 13) avec un contrôleur principal (10) qui, par exemple, peut interroger les contrôleurs asservis (11) pour déterminer leur état ou l'état des différents dispositifs qu'ils contrôlent.
