12.4.1.2 PROFIBUS Cable
The PROFIBUS network supports two kinds of communication media, RS-485 electric cable and
optical fiber. Currently we mainly face the customers using the wired medium though we also have
the devices which support the wireless communication.
Delta provides the standard PROFIBUS cable to the customers for purchase. The order number of
the cable is 4009414800. The PROFIBUS cable is the two-wire twisted shielded cable and the two
wires inside the cable, A-green and B-red are connected to the pin 3(B) and 8(A) of the DP
interface respectively. The part near the cable skin is filled with the woven net and aluminum foil as
the shielded layer. The skin of the cable is purple as below.
The characteristic impedance of the PROFIBUS cable should be from 100Ω to 220Ω, the cable
capacitance between the conductors should be less than 60pF/m and the cross section of the
cable should exceed 0.22mm2 (24 AWG).
