  • the motion control receives the required setpoints and the start movement via the fieldbus line connection and links these back to the higher-level system with the position and a status display. Further advantages result from the fact that the transmission of data between the programmable logic controller and the axis controller is time-critical and safe.
  • Application software modules can be standardized. Material costs and installation and time wiring costs can be reduced. The electrical susceptibility is reduced. Likewise, the maintenance is reduced. Times for assembly and commissioning are reduced.

Abstract

Machine (1) pour la coulée continue d'aciers, qui possède une coquille (6) de coulée continue constituée d'un moule de coulée (10) comportant des plaques (11) de côtés larges et des plaques (13) de côtés étroits sur lesquelles sont montées des unités piston-cylindre (16) en tant qu'actionneurs et paliers de support. La position desdites unités piston-cylindre est mesurée à l'aide d'appareils de mesure de champ (21), et les données de mesure sont mises en mémoire via des modules (22) de bus de champ en tant que signaux BUS dans une unité de commande (23) de la machine (1) pour la coulée continue et peuvent être renvoyées aux actionneurs après traitement en tant que signaux de commande. L'objet de la présente invention est la collecte des données de mesure sur place sur la coquille (6) de coulée continue et le traitement sur place desdites données. A cet effet, le vérin hydraulique (16a) respectif est connecté à un groupe de soupapes (24) pourvu d'une boîte de bornes fixe (25) pour les lignes (28) des signaux de mesure et de commande, et la boîte de bornes (25) est connectée à un élément de commande (30) d'axes à partir duquel le module (22) de bus de champ achemine les signaux vers un dispositif de commande (31) à programme enregistré.
