Abstract: Timers of a plurality of slave units are synchronized with a timer of a master unit by a) sending a synchronization message on the first network by the master unit, which contains a time measurement of the master unit and a time scale, to the slave units; b) at each slave unit, forming the difference between a time measurement recorded in the slave unit and the time measurement received by the master unit, and correcting the current time measurement of the slave unit by this difference, and, at each unit, the recording of a time measurement upon receipt of the time scale; c) at the master unit, inserting the recorded time measurement into a subsequent synchronization message.

Abstract: A method and a device for determining the system load of a processor system. The processor system transmits a process status via an interface, an active process status indicating that an active process is being executed. The active process status is transmitted to a protocol device. The protocol device records a first time interval, a first time interval corresponding to a time interval for which an active process status exists. The protocol device determines a system load existing within a monitoring period by relating the first time intervals which were recorded within this monitoring period to the duration of the monitoring period.
