Procedure:
See fig. 2.
1. Connect the red conductor(s) to terminal B
(pos. 1).
2. Connect the green conductor(s) to terminal A
(pos. 2).
3. Connect the cable screens to earth via the earth
clamp (pos. 3).
It is important to connect the screen to
earth through the earth clamp and to

3.2 Setting the Profibus address

The CIM 1XX Profibus module has two hexadecimal
rotary switches for setting the Profibus address.
The two switches are used for setting the four most
significant bits (SW3) and the four least significant
bits (SW4), respectively. See fig. 3.
