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:
S
IM 300-3, IM 300-5, IM 301-3, IM 301-5 and IM 304
as well as the CC interface modules:
S
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.”
