The present invention provides a method and a communications system for the exchange of data between at least two users who are in contact with one another using a bus system. The data are included in messages which are transmitted by users over the bus system. A specifiable priority is assigned to each message. In order to achieve, in the normal case, a high probability of a short latency period (t) of a message to be transmitted, and to be able to guarantee, in the worst case, a maximum latency period (tmax), it is provided that the priorities assigned to the messages be dynamically modified during the operation of bus system. Preferably, the set of all messages is subdivided into equivalence classes, and a priority is assigned to each equivalence class. During the operation of the bus system, the priorities of the messages are dynamically modified within an equivalence class, and the priorities of the equivalence classes are dynamically modified.
