Centralized Configurations
A central controller (CC 0, CC 1, CC 2 or CC 3) connected via short connecting cables to as many as
three expansion units makes up a centralized configuration. Use only the IM 305 or IM 306
interface modules to connect an ER 701-1 mounting rack.
For centralized configuration with the IM 305, please note the following points:
•
You can use fixed slot addressing only (see Chapter 5).
•
The 0.5 m (1.6 ft.) connecting cable is not long enough to connect the EU under the CC. Use an
IM 306 interface module or the IM 305 version with a longer cable for such an arrangement.

You can also order a 1.25 m (4.1 ft.) 705 connecting cable (Order No. 6ES5 705-0BB20) or a 2.5 m (6.7 ft.) 705 con-
necting cable (Order No. 6SE5 705-0BC50), and use them to mount two EUs next to each other.
