Interface Modules
Various interface modules (IMs) are available for communication
between a central controller and expansion units, and between
expansion units. Interface modules in the central controller are known
as EU interface modules; those inserted in an EU are known as CC
interface modules.
This chapter describes the EU interface modules:
••
IM 300-3, IM 300-5, IM 301-3, IM 301-5 and IM 304
as well as the CC interface modules:
••
IM 312-3, IM 312-5, IM 310 and IM 314
Other IMs such as the IM 307-IM 317 and the IM 308-IM 318 are
described in separate manuals (see Catalog ST 54.1). The IM 306 CC
interface module is described in the S5-115U PLC manual.
A general overview of the applications of individual IMs can be found
in Chapter 2: "Centralized and Distributed Configuration of a
Programmable Controller".
