The role of field bus PROFIBUS DP/FMS isolation repeater is also discussed
As far as DP is concerned, a repeater must be added every 32 DP devices according to specifications. The relay acts as follows1, photoelectric isolation signal, 2, can change the topology (if necessary, can produce a tree branch) 3, cut and cut terminal resistance4, to enhance the signal, optimize the waveform and extend the communication distance
The industrial design of PROFIBUS optical fiber communication repeater and DP/FMS bus signal isolation and data communication, with the total line photoelectric isolation, signal regeneration, extend the transmission distance, increase the number of nodes and other functions.
