Definitions

• the invention relates to a continuous casting machine with a continuous casting mold for the casting of liquid metals, in particular steel materials, with the casting forming wide side plates between which are arranged on both sides to form the G confusestrangbreite taking into account the shrinkage of the casting strand adjustable narrow side plates, in each case two vertically spaced pistons Cylinder units are provided as actuators and support bearings whose position measured by field measuring devices, transferred the measurement data via fieldbus modules as BUS signals in a BUS line and stored in a control of the continuous casting machine and traceable after processing as control signals to the actuators ,
• Such a continuous casting machine is known from WO 01/94052 A1.
• a continuous casting machine for decentralized casting data processing of the measuring data obtained by sensors on a continuous casting mold is described in a process computer of the control of the continuous casting plant.
• the decentralized recording of the measured data makes the measuring section more efficient and simplifies the measuring equipment by the measurement and control data collected in cooled fieldbus modules directly on the continuous casting mold and transferred in BUS signals in a BUS line and stored at least in the control of the continuous casting and / or processed.
• the object of the invention is to record the measured data in the area of the continuous casting mold in cooled field devices and to process them on site.
• the hydraulic cylinder of the piston-cylinder units is connected in each case to a valve stand arranged in the region of the continuous casting mold or the continuous casting control with a stationary terminal box for the measuring and control signal lines and the terminal box is connected to an axis regulator from which the fieldbus module leads the signals to a programmable logic controller.
• Advantages result from a lower cabling effort with shorter distances between the modules.
• the main advantage is the axis controller.
• the axis controllers are special microprocessor-based circuits used to control servo axes.
• the standard software in motion control adds a real-time control for axis adjustment.

• Machine or step position transducer - digital or analog inputs or outputs, a Profibus, a network.
• the motion control used for the application comprises a remote control and a data display device (display).
• the application software is standard and stored in a recallable memory.
• the motion control is able to control multiple axes (hydraulic piston-cylinder units). Based on a graphical menu, the motion control is adjusted via parameters to the axis type and to the type of position feedback. Programming is not necessary.
• 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.
