Abstract
In a method for time coordination of the transmission of cyclic data values on a bus to which data transmitters and data receivers are connected, each data transmitter is assigned a cycle time in which it periodically transmits its data values, wherein the cycle times are integer multiples of a minimum cycle time. Furthermore, each data value is assigned a delay time related to the start of the cycle time of its data transmitter. A synchronization message is transmitted via the bus to each data transmitter with a period corresponding to the cycle time of the respective data transmitter and has a phase which is specific for the data transmitter with respect to the start of the minimum cycle time. The reception of its synchronization message in each data transmitter initiates the transmission of its data values with the respective delay time.
