Abstract

L'invention concerne une machine de transformation de plastiques, notamment une machine de moulage par injection, comprenant au moins une unité d'exploitation, au moins une commande de machine, ainsi qu'au moins un sous-système avec son propre système de commande. La commande de machine et le dispositif de commande produisent dans chaque cas une sortie écran et peuvent être utilisés par ce biais. Au moins une des unités d'exploitation est reliée ou peut être reliée aussi bien à la commande de machine qu'à au moins un dispositif de commande pour transmettre des données. Jusqu'à présent, il était difficile, dans le cas de machines de transformation des plastiques, notamment celles comportant plusieurs sous-systèmes, d'effectuer une commande coordonnée des éléments individuels d'une seule unité d'exploitation. Dans le cas d'une machine de transformation des plastiques, qui garantit une observation et une utilisation simples, aussi bien de la commande de machine que des dispositifs de commande de sous-systèmes, il est prévu selon l'invention, que la sortie écran de la commande de machine (au moins au nombre de une), ainsi que celle du dispositif de commande (au moins au nombre de un) puissent être affichées sur l'écran de l'unité d'exploitation (au moins au nombre de une) et que les entrées effectuées sur l'écran dans chaque sortie écran puissent être retransmises au dispositif d'où la sortie écran provient.
