COMMUNICATION METHOD IN A MRI SYSTEM
First Claim
1. A method of communication on a multidrop bus of a magnetic resonance system, employing an adaptive protocol script for telegrams on said multidrop bus comprising the steps of:
- with said adaptive protocol script for telegrams on said multidrop bus, implementing adaptive protocol matching using telegram start characters, addresses and frame type binding;
decomposing a telegram frame into a device-based link layer and a service layer using said link layer for differentiating addresses and frame types and enables enabling devices which use different communication protocols to be simultaneously present on said bus; and
said service layer constituting the load of said link layer and the service script thereof being operation-based and providing, for the exterior, interfaces which are independent of the communication protocols which are used by said devices.

Abstract
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.
