A plastics processing machine, particularly an injection molding machine, with an operating unit, a machine controller, and a subsystem having its own dedicated control unit is described. The machine controller and control device each generate a screen display and can be operated via the screen display. The operating unit is connected or can be connected for data transmission to both the machine controller and the control unit. Both of the machine controller and the control unit can be monitored and controlled by reproducing the original screen output from the machine controller and the control unit on the display screen of the operating unit, where new information can be entered. The information entered on the display screen of the operating unit is then transmitted back to the corresponding controller or unit associated with the reproduced screen display where the information was entered.

Plastics processing machine

A plastics processing machine, in particular injection molding machine or extruder, includes at least one component represented by a clamping unit, feed and metering apparatus, plasticizing unit, injection unit, or separate injection apparatus, and characterized by specific parameters for carrying out at least one working or process step. A control device is connected to the at least one component and configured to control the at least one component, with the component-specific parameters being useable in the control device for control of the component. Provided for the component is a separate memory device in which the component-specific parameters are stored and can be transmitted to the control device prior to or upon startup of operation of the component.

Identification of a modular machine component

A control system for a plastics processing machine with at least one central processing unit with a real-time operating system is described. The central processing unit is connected to a plurality of actuators and/or sensors via a bus system, with at least one actuator and/or sensor directed to a rapidly fluctuating variable with a high-resolution. The first central processing unit can be released of overly burdensome control and communication tasks by using a first pre-processing unit which performs signal pre-processing for several sensors and/or actuators and by using a second pre-processing unit, which relieves the central processing unit directly of the bus communication.
