Abstract

La présente invention porte sur un dispositif d'affichage programmable, qui est connecté de manière à pouvoir communiquer avec un dispositif de commande qui commande un dispositif commandé, et qui affiche des écrans contenant des conditions concernant le dispositif de commande, et qui joue le rôle d'interface utilisateur pour le dispositif de commande, lequel dispositif d'affichage programmable est équipé: d'une unité de mémoire non volatile qui stocke de multiples instances de données d'écran qui ont été créées par un dispositif de création de données d'écran externe et sont destinées à assurer un affichage contenant des conditions concernant le dispositif de commande; d'une unité d'entrée dans laquelle diverses informations sont introduites; d'une unité d'affichage qui affiche les données d'écran sous la forme d'un écran; et d'une unité de traitement d'affichage d'écrans, qui divise l'unité d'affichage en de multiples régions d'affichage, sur la base d'informations d'instruction d'affichage d'écrans divisés réduits qui sont introduites par l'unité d'entrée et donnent l'instruction de diviser l'unité d'affichage et d'afficher les multiples instances de données d'écran sur des écrans réduits, et qui réduit les multiples instances de données d'écran stockées dans l'unité de mémoire non volatile et les affiche sur les multiples régions d'affichage divisées, affichant ainsi les multiples instances de données d'écran sous la forme d'écrans divisés réduits sur l'unité d'affichage.
