Data transfer
technology to the
Profibus standard
Network topology Linear bus, active bus terminator at both ends, branch
lines are possible
Medium Shielded twisted cable, shielding may be dispensed with in
suitable environments (electromagnetic compatibility)
Number of stations 32 stations in each segment without repeaters, extendible
to 127 with repeaters
Max. bus length
without repeaters
100 m at 12 Mbit/s
200 m at 1500 Kbit/s, up to 1.2 km at 93.75 Kbit/s
with repeaters Using repeaters (line amplifiers) increases the max. bus
length to the order of 10 km. The number of possible
repeaters is at least 3 and may be up to 10, depending on
the manufacturer
Transfer rates 9.6, 19.2, 93.75, 187.5, 500, 1500 Kbit/s, up to 12 Mbit/s in
discrete steps
Plug 9-Pin D-Sub plug
