Abstract
The system provides for one single cable with four electrical conductors (16 to 19). Two of the conductors (18, 19) form a field bus line for the signal transmission, and the other two conductors (16, 17) form an energy line for providing energy supply. All signal transmitters (1, 2) and signal receivers (3, 4) are connected to the cable, and the cable (16-19) is fitted at both ends with a line termination (20-22). Each signal transmitter (1, 2) and each signal receiver (3, 4) has a field bus controller (8, 10). The entire signal transmission takes place via the two-wire field bus line (18, 19).
