Abstract

Several sets of pulse coded data may be transmitted by a TDM cycle pref. controlled by a computer, over a data channel, and a two-wire busbar (8) is provided for transmission of data and transmitter for current supply to the measurement points: A control point (1) has an address transmitter (3) and a data receiver (4) and each measurement point has an address receiver (6) and a data transmitter (7) and each receiver (6) compares the address sent by the transmitter (3) with a fixed address, and when they coincide, the transmitter (7) is activated in order to transmit the measurement results.
