A device for synchronizing processes which run on a plurality of units including a central unit linked with other units via a field bus, includes a device provided in the central unit for producing a system clock, the field bus having a vacant line for distributing the system clock to the other units, and respective multiplication devices located at the other units for multiplying the system clock; and a method of operating the device for synchronizing processes.

A device for monitoring safety-relevant processes in actuating/drive elements in machines having at least one operation control for safety-relevant and other than safety-relevant processes, at least one safety monitoring control, at least one safety input/output device and a redundantly constructed input/output system for safety-relevant processes, includes at least one field bus system connecting the operation control, the at least one safety input/output device and the at least one safety monitoring control to one another, at least one of the safety input/output device and the safety monitoring control being disposed in a distributed manner on an actuating/drive element for, respectively, initiating and performing a safety-relevant process; and a method of operating the device.

Method of automatically controlling and regulating a chronological sequence of operations of a printing press includes initializing in RAM of a computer a list entered from ROM and having a table of all press operation data necessary for printing, including an assignment of times for actuating actuators to position data of the printing carrier, modifying the data entered into the list in accordance with data regarding the machine status, and with respect to process values relative to a position of the printing carrier at which a performance of an operation should start, a first press operation to be performed being defined and, included in the data for every operation is the operation to be performed preceding and subsequent thereto and, upon reaching a starting position of each actual operation to be performed in accordance with actual data from the speed sensor, with the data about the machine status and with the process values, and redetermining in the computer and entering into the list the data for the position at the start of the performance of the actual operation, and the data for the operation preceding and subsequent to the actual operation, and if a shifting of the performance sequence is necessary, redetermining the data of the future preceding and subsequent operations. If the redetermined position chronologically comes after the starting position, the respective operation skipped in the performance sequence, and if the redetermined position chronologically comes before the starting position, the respective operation is performed from the starting position.
