A dialogue system uses a three wire bus connecting a central station with a plurality of substations with two of the wires carrying an AC supply voltage and a third one of the wires carrying data by means of a closed loop of the AC carrying wires and the third wire. The central station uses a series connection of a data transmitter and a data receiver with the third data wire and each substation includes a data receiver in series with the data wire and a data transmitter between the data wire and both AC wires.

Data communication system

For the implementation of a regulating and/or control system under use of a microprocessor, the system first is arranged column by column and line by line in a functional diagram. The input values of the system are written in an X-register line by line. Also, parameters are written line by line and column by column into a parameter register. An interpreting computer combines line by line and column by column the input values, respectively, the parameters with the predetermined function with the computer being instructed by a program stored in a configurator. The output values of the interpreting computer per column are written line by line in a Y-register. The contents of the Y-register is transferred back into the X-register if the maximum number of lines of the respective column is run through and the maximum number of columns is not yet reached. On the other hand, the contents of the Y-register is delivered as an output if the maximum number of lines of the respective column is run through and the maximum number of lines is reached.
