Method for transferring data between equipments of a serial communication system in the form of a ring , wherein a priority control protocol is provided and at least one slave transmits using the priority control protocol a request to a master in a data packet, and corresponding communication system

摘要

The method involves transmitting a data packet from a participant formed as a master (4) to another participant formed as a slave (6), and transmitting the data packet from the slave to other slaves (8, 10). Address information of the data packet is changed by each slave, and an address value of the received data packet is changed such as added and subtracted, by the slaves around a fixed value as the address information, where the slaves have identical local addresses. An identical communication algorithm is stored in the slaves. An independent claim is also included for a communication arrangement comprising participants connected in series with each other.
