A data transmission system has a number of control devices connected via a transmission loop. Each control device includes signal processing circuitry which compiles data signals to be transmitted in the form of a data signal block. The signal processing circuitry is followed by a transmit buffer which, includes a write/read memory. A prepared data signal block can be accepted into this memory. A counter is connected to the memory which continuously addresses the memory for accepting a data signal block, and for emission thereof to the loop upon the appearance of a transmit authorization signal. The write/read memory is followed by a register. In addition to memory locations for accepting a …
