    摘要: The present invention relates to a device and a method for synchronizing processes which are executed on a plurality of units (2a, 2b, 2c), in particular, in paper-processing machines, the units (2a, 2b, 2c) being connected to a central control unit (1) via a data bus (6). The present invention is characterized in that the central control unit (1) is designed for distributing movement commands via a data bus (6) to a plurality of units (2a, 2b, 2c), the movement commands containing the instant at which these commands are executed, and that provision is made for the units (2a, 2b, 2c) which keep available the absolute time to synchronously execute these commands at the instant communicated via the commands.
