Abstract

Method of synchronizing at least one user of a bus system which is operated with a preselectable system clock period (NTU), a local clock period (LNTU) and a reference clock period (GNTU) being preselected for the at least one user, and the reference clock period (GNTU) being synchronized with the system clock period (NTU), a local clock period (SLNTU), synchronized with the system clock period (NTU), of the at least one user being generated by linking the local clock period (LNTU) to a scaling factor (P), the scaling factor (P) reflecting a ratio of the reference clock period (GNTU) to the local clock period (LNTU), the scaling factor (P) for synchronization of the local clock period (LNTU) being adapted to the system clock period (NTU) by addition or subtraction of an adjustment value (O).
