A method and a communication system for exchanging data between at least two users interconnected over a bus system are described. The data is contained in messages which are transmitted by the users over the bus system. To improve data exchange among users so that in the normal case, there is a high probability that it will be possible to transmit messages with a low latency, while on the other hand, in the worst case, a finite maximum latency can be guaranteed, the data be transmitted in an event-oriented method over the bus system as long as a preselectable latency period elapsing between a transmission request by a user and the actual transmission operation of the user can be guaranteed for each message to be transmitted as a function of the utilization of capacity of the bus system, and otherwise the data is transmitted over the bus system by a deterministic method.
