Title: An arrangement for the transmission of signals via a field bus
Inventor: HANSEMANN HEINRICH
IPC: H04L5/00
Filed: 1996-09-11
Granted: 1999-06-21
Abstract: In measurement and monitoring systems of industrial installations every signal transmitter has so far been connected to the associated signal receiver via a separate cable. The consequence of the plurality of signal transmitters frequently necessary is a plurality of cables. The new arrangement provides one single cable of four electrical conductors. Two conductors form a field bus head for the transmission of the signals and the other two conductors form a power lead for the power supply. To this cable are connected all of the signal transmitters and signal receivers, and the cable is provided at both ends with a lead termination. Each signal transmitter and each signal receivers exhibits a field bus control device, preferably a CAN-bus. The whole signal transmission is effected over the two-core field bus lead, a high signal-to-noise ratio existing between the signal transmission and the state of rest. The sensitivity to disturbance from the entry of electro-magnetic radiation from outside is also particularly low.
