MACHINE UNIT OF A PRINTING SYSTEM HAVING AT LEAST ONE ACTUATOR WHICH IS CONTROLLED BY A CONTROL UNIT

摘要

The application relates to a machine unit of a printing system (01) having at least one actuator (04), which is controlled by a control unit (03), wherein said control unit (03) and said at least one actuator (04) are connected to a digital network (09), wherein said control unit (03) and at least one user interface (11) for actuating said at least one actuator (04) are also connected to a digital network (12), wherein the digital network (09) connecting said at least one actuator (04) to said control unit (03) for data processing is implemented separately and differently from the digital network (12) connecting the at least one user interface (11) to said control unit (03) for data processing, wherein a transmission of data transmitted at least from said user interface (11) to said control unit (03), the transmission being performed along a data transmission link between said control unit (03) and said at least one user interface (11) in said digital network (12) that connects said control unit (03) and said user interface (11), is monitored by at least two processes, which are operated independently of one another.
