In a method of communication on a multidrop bus of a magnetic resonance system, an adaptive protocol script for telegrams on the multidrop bus is used, that implements adaptive protocol matching using telegram start characters, addresses and frame-type binding. For this purpose, a telegram frame is divided into a link layer and a service layer, the link layer being device-based and being responsible for differentiating addresses and frame types, and enabling devices that use different communication protocols to be simultaneously present on the bus. The service layer represents the load of the link layer, and its service script is operation-based, and the service layer provides, for the exterior, interfaces that are independent of the communication protocols used by the devices.
