Abstract

A serial transmission of data takes place on a bus (10) which has at least one forward line (8) and one return line (9) and is connected to a plurality of slaves (S1, S2, . . . ) and via whose forward line (8) successive data frames (R1, R2, . . . ) for successive slaves (S1, S2, . . . ) are transmitted. Each slave (S1, S2, . . . ) gates out, in the process, from the forward line (8) the data frame (R1, R2, . . . ) which is provided for it, and diverts said data frame (R1, R2, . . . ) directly to the return line (9) after processing. The transmission of data can therefore be carried out very quickly and with a high response speed.
