ABSTRACT:
A method for synchronizing a data exchange between a data source and a control device is provided. A synchronization request signal is first transmitted via the bus system to the data source, which then measures a signal propagation time from the control device to the data source. In the data source, a transmission delay time is set which is dependent on the measured signal propagation time. Data which are to be transmitted are delayed by the transmission delay time. A bus system for synchronizing a data exchange is also provided. After receiving a synchronization request signal, the data source measures signal propagation times and sets a transmission delay time in a transmission delay device on the basis of the measured signal propagation times.
