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.
To install a PLC in a distributed configuration, you must observe the
following conditions:
Note
The IM 307/317, IM 308/318 and IM 308-B/318-B each have their own
manual (see catalog).

With the IM 301/IM 310 pair of interface modules, you can only use I/O
modules (DI, DO, AI, AO) and IPs without page addressing in the EUs.
With the IM 304/314 pair of interface modules, you can use all IPs, CPs
and I/O modules in the EU 185U.
