Bus system, station for use in a bus system, and bus interface

The invention relates to a bus system, comprising by a bus wherein the first) is signal transmission and second). The bus is arranged is made to the the first repeatedly to the second the transmission and protocol to the data inquiry machine. The protocol comprises a request from the first communication speed transmission according to the first support format the first), with a according to the second riding format of the second transmission speed of the holder at least a second mode. The second) is arranged as comprises a mode of first and second pattern mode a receiving from one connected with the support, and is arranged as; if it is arranged is made of the substrate of the first mode operation of switch is connected with the first indication the first, and; if it is arranged is made of the substrate to the second operation mode to give to the second indication the first). The first) comprises a processor, a controller and a decoder. The processor is made of a handle attribute of the first support format and production. The controller is made from of the barrier property of the first support format generating request device and is used for detecting the arrived of the first instruction to the support is transmitted to the second) of the first support format, and detection arrived the second instruction to the request to retransmit to the decoder. The decoder is used to the support is provided with a second format transmits to the second).
