Abstract

L'invention concerne un procédé d'affichage de valeurs de paramètres d'appareils sur des commutateurs industriels, dans lesquels le réglage des paramètres des commutateurs peut être effectué par télécommande et qui comportent en outre des dispositifs permettant de lire directement ces valeurs de paramètres sur le commutateur. L'invention concerne en outre un dispositif de réalisation du procédé selon l'invention. L'objet de l'invention est un procédé visant à garantir la conformité d'une valeur de paramètre réglée momentanément d'un commutateur industriel avec l'affichage de cette valeur sur l'appareil lui-même, le paramètre de commutateur pouvant être réglé au moyen d'un dispositif de réglage sur l'appareil lui-même ainsi que par télécommande, et l'affichage de la valeur de paramètre se trouvant sur un écran séparé. L'objet de l'invention concerne également un dispositif de réalisation du procédé. Selon l'invention, la valeur de paramètre affichée à l'écran est lue à partir du dispositif de réglage de l'appareil. La transmission de la valeur de paramètre du dispositif de réglage à l'écran peut être effectuée à une fréquence constante, une annonce unique n'étant effectuée que si la valeur du paramètre est modifiée. En outre, selon l'invention, lors du réglage d'un paramètre de commutateur au moyen d'un équipement électromécanique, le dispositif de réglage du paramètre de commutateur sur l'appareil lui-même comporte un servomoteur qui est commandé lors du réglage à distance de la valeur de paramètre correspondante et qui asservit le dispositif de réglage en conséquence.
