• IEC 61158-2 (MBP)
PROFIBUS DP
The IEC 61158 standard specifies two types of cable (A and B) for the bus line which can be used for
every transmission rate. Cable type A is recommended.
Cable type A
Characteristic impedance 135 to 165 Ω at a measuring frequency of 3 to 20 MHz
Cable capacitance < 30 pF/m
Wire cross-section
> 0.34 mm
2
(22 AWG)
Cable type Twisted pairs
Loop resistance ≤110 Ω/km
Signal damping Max. 9 dB over the entire length of the cable cross-section
Shield Copper braided shielding or braided shielding with foil shield. When grounding
the cable shield, observe the grounding concept of the plant.
