To install a PLC in a centralized configuration, you must observe the
following conditions:
••
A centralized configuration is generally only suitable for
connecting I/O modules (DI, DQ, AI, AQ) and some intelligent
I/O modules (IPs) in the EU (see the Configuring Aids in the
catalog and Chapter 4).
••
The line length between the IM in the CC and the last IM in the
EU must not exceed 2 m.

Installing a PLC with
Distributed Configuration
To install a PLC in a distributed configuration, you have a choice of
parallel/symmetrical and serial communication. The following table
shows which interfaces and connecting cables can be used to connect
the various expansion units (EUs/ERs) to the CC in a distributed
configuration.

The last IM 310 or IM 314 always requires a 6ES5 760-1AA11 terminator.
The ER 701-2 and ER 701-3 always additionally require an IM 306
for communication via an IM 304, IM 307 or IM 308.
