Overview

• To connect distributed I/Os over PROFIBUS DP

• Max. transmission rate 12 Mbit/s

• Electrically isolated RS 485 interface

• Connection via 9-pin sub-D connector

• The following connection options are available for each

S7-400 CPU:

- A PROFIBUS module in the CPUs 414-3, 414(F)-3 PN/DP,

416-3, 416(F)-3 PN/DP

- Two PROFIBUS modules in the CPU 417-4

Note:

Input current

from CPU, max. 150 mA; Current consumption from

S7-400 bus: The module uses no

current at 24 V, it provides this volt-

age only at the DP interface. Total

current consumption of the compo-

nents connected to the DP interface,

but maximum 150 mA. Current car-

rying capacity of the isolated 5 V

(P5ext) maximum 90 mA, current

carrying capacity of the 24 V maxi-

mum 150 mA.

Power losses
