7.1 Using SIMATIC S5 Expansion Units in an S7-400

Area of Application

The IM 463-2 interface module is used for distributed connection of S5 expansion
units to an S7-400.
You can use the IM 463-2 in the CR of the S7-400. In the S5 expansion unit, you
use an IM 314.
This allows you to connect the following S5 expansion units to an S7-400:
•EU 183U
•EU 185U
•EU 186U
•ER 701-2
•ER 701-3
Accordingly, you can use all digital and analog I/O modules suitable for these EUs
or ERs.

Basic Requirement

If you connect an S5 expansion unit to a CR of the S7-400 via an IM 463-2, the
SIMATIC S5 basic requirements concerning EMC, ambient conditions, etc., apply
for the overall system.
Note
In environments contaminated by radiated noise, you must apply the type 721
cable shield (see Installation Manual, Chapter 4).

Expanding the Distributed Connection

You can also centrally expand the EUs connected in a distributed configuration via
an IM 463-2. The following table lists the S5 interface modules that you can use for
this purpose.
