More Information
Summary: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 data signal word, this register additionally includes memory locations for auxiliary information to be attached to the individual data signal words. The auxiliary information is derived from counter readings of the counter.
