Abstract: A data transmission system with distributed control functionality for machine tools, production machines, and robots, having a plurality of control functional units, has a respectively networked movement control system which controls the operation of the control functional units in complex processes. Information relating to movement control can be interchanged by means of real-time cross-communication between the control functional units. An Ethernet link can be used for real-time cross-communication. The use of the data transmission system for printing machines also represents an advantageous application of the invention.

Abstract: The objective is to reduce the downtime of a printing system in the printing industry. Provision is therefore made to supply the drive regulators (3) of a printing system (1) simultaneously with a plurality of clock signals. Each of the drive regulators (3) independently selects one of the clock signals for synchronization. In the event of failure of a signal source, the printing system is not interrupted but the drive regulators (3) switch automatically to the clock still present.

Abstract: The invention relates to a printing press and a method for operating a printing press comprising at least one print unit, a drive unit that is assigned to the print unit, a control unit at least for regulating a drive unit, and a print mark measuring device, register measuring device, or register mark measuring devices. The print mark measuring device, or the register measuring device is directly connected to the control unit provided at least for regulating a drive unit by means of a signal transmission means. The print mark measuring device directly transmits a print mark signal to the control unit, the control unit calculating a correction factor for regulating the movement of at least one drive unit such that the printing quality is improved.

Abstract: The invention relates to a control method and a control device for the operation of rotationally or linearly driven axes with a position control. This involves determining the difference between the setpoint position value (LS) and actual position value (WI) caused by an additional movement component during the time period of the occurrence of at least one superposed movement by subtraction of one value from the other. Furthermore, it is possible to eliminate movement components which are known, periodic and can be mathematically determined as desired from all the required control data paths during the time period of the superposed movement.

Abstract: The invention relates to a closed-loop control method for operation of individually driven rotating machine elements (M1, M2) with angle position control, which elements are coupled with a force fit or via a common load (L). In this case, parameters (UP) that describe the circumference of the driven corresponding machine elements (M1, M2) are supplied as a correction variable in the form of an angle position error (WA) to the input of the angle position regulator (WR). These may be diameters or radii of machine elements (M1, M2) which are involved, as well as a diameter and at least one diameter difference, or at least one radius and at least one radius difference.

Abstract: The invention relates to a data path selection device (DS1-DS6) having at least two data terminals for a line-bound data transmission system. Any desired data path connections (DV) can be set between the data terminals of the data path selection device (DS1-DS6). The data path connections (DV) can be defined via an existing or an additional setting signal input (E), by means of a setting signal. The electrical isolation of data terminals and use of a data connection (D, AB) with a real-time capability, such as a real-time-capable Ethernet connection, are a feature of the invention.
