Notes on Using this Manual
The S5-135U/155U PLC is a member of the family of SIMATIC S5
programmable (logic) controllers. The controller can be used in single and in
multiprocessor operation with up to four CPUs. In multiprocessor operation,
each CPU processes its individual user program independently of the other
CPUs (multicomputing).
CPUs Available
The following are available as CPUs:

How the Manual is
Organized
Given as a guide in the following are pointers on how this manual is
organized; they will assist you when using your S5-135U/155U
programmable controller.
At the start of this manual you will find the “Safety-Related Guidelines”
and the “ESD Guidelines.” You must observe these to the letter and
follow them during the entire time you are working with the
S5-135U/155U PLC. If your PLC requires repair, you must observe the
Repair Guidelines in Section 4.1.4.
Chapter 3 contains the Installation Guidelines with information on
interference-free installation of the S5-135U/155U PLC.
Which of the remaining chapters of this manual you may require when
working with your PLC will depend on the extent of your automation task
and on the configuration of your PLC.
For a basic configuration in single-processor operation without expansion
units, you will need the following chapters:
Chapter 4 describes the central controller (CC) in Section 4.1. Described
are the technical features, installation, startup and maintenance of the CC.
Section 4.3 describes the power supply units. You will find a separate
description of the 6ES5 955-3NA12 power supply unit in Section 4.5.
Both sections describe the installation and startup as well as the necessary
maintenance on the power supply units. The 24 V/4 A load power supply
is described in Section 4.4.
Chapter 5 contains the instructions for the individual CPUs. Described
here are the technical features, installation and startup of the individual
CPUs. The various methods of operating the CPUs are also described, as
are the CPU statuses where they can be directly indicated by the LEDs on
the module. If you use memory submodules or memory cards (CPU 948),
you can look up the necessary information in Sections 5.7 to 5.9.
Chapter 8 and Chapter 9 describe the digital and analog I/O modules.
Described here are the installation, wiring and operation of these
modules. Individual I/O modules exhibit specific features which are
discussed in separate chapters.
To configure your PLC with expansion units (EUs) you will need the
following chapters:
Chapter 2 shows how you can configure a PLC with expansion units in a
centralized or distributed arrangement.
Described in Chapter 4, Section 4.2, are the EU 183U, EU 184U, EU
185U and EU 187U. Those EUs which operate with their own power
supply unit are described in Section 4.3.
Chapter 7 describes the interface modules (IMs) which serve for data
communication between central controllers and expansion units.

Notes on Using this Manual and on the CE Symbol
To operate two or more CPUs in multiprocessor mode in your PLC, you will
need Chapter 6.
Chapter 6 describes multiprocessor operation. This chapter contains all
the measures you must take for startup of the PLC in multiprocessor
operation. Described in Sections 6.5 and 6.6 are the 923C and 923A
coordinators.
In Chapter 11 are the connector assignments of the individual modules and
subracks.

Introduction
The SIMATIC programmable controller is not a machine in the sense of the
EC Directive on machines. Therefore, there is no declaration of conformity
for SIMATIC as regards the EC Directive 89/392/EEC on machines.
EC Directive
89/392/EEC on
Machines
The EC Directive 89/392/EEC on machines controls machine requirements.
Here, a machine is understood to be the entire sum of devices or parts
involved (see also EN 292-1, paragraph 3.1).
SIMATIC is part of the electrical equipment for a machine and must
therefore be included in the procedure for checking conformity by the
machine manufacturer.

Notes on Using this Manual and on the CE Symbol
Risks Involved in the Use of So-Called SIMATIC-Compatible Modules of
Non-Siemens Manufacture
“The manufacturer of a product (SIMATIC in this case) is under the general
obligation to give warning of possible risks attached to his product. This
obligation has been extended in recent court rulings to include parts supplied
by other vendors. Accordingly, the manufacturer is obliged to observe and
recognize such hazards as may arise when a product is combined with
products of other manufacture.
For this reason, we feel obliged to warn our customers who use SIMATIC
products not to install so-called SIMATIC-compatible modules of other
manufacture in the form of replacement or add-on modules in SIMATIC
systems.
Our products undergo a strict quality assurance procedure. We have no
knowledge as to whether outside manufacturers of so-called
SIMATIC-compatible modules have any quality assurance at all or one that is
nearly equivalent to ours. These so-called SIMATIC-compatible modules are
not marketed in agreement with Siemens; we have never recommended the
use of so-called SIMATIC-compatible modules of other manufacture. The
advertising of these other manufacturers for so-called SIMATIC-compatible
modules wrongly creates the impression that the subject advertised in
periodicals, catalogs, or at exhibitions had been agreed with us. Where
so-called SIMATIC-compatible modules of non-Siemens manufacture are
combined with our SIMATIC automation systems, we have a case of our
product being used contrary to recommendations. Because of the variety of
applications of our SIMATIC automation systems and the large number of
these products marketed worldwide, we cannot give a concrete description
specifically analyzing the hazards created by these so-called
SIMATIC-compatible modules. It is beyond the manufacturer ’s capabilities
to have all these so-called SIMATIC-compatible modules checked for their
effect on our SIMATIC products. If the use of so-called SIMATIC-compatible
modules leads to defects in a SIMATIC automation system, no warranty for
such systems will be given by Siemens.
System Manual
C79000-G8576-C199-06
In the event of product liability damages due to the use of so-called
SIMATIC-compatible modules, Siemens are not liable since we took timely
action in warning users of the potential hazards involved in so-called
SIMATIC-compatible modules.”

Centralized and Distributed Configuration of a Programmable Controller
This chapter contains an overview of the methods of configuring an
S5-135U/155U PLC. You will find a description of the types of
communication between a central controller and the expansion units, and an
overview of the interface modules required for the different types of

Centralized and Distributed Configuration of a Programmable Controller
2.1 Application
The S5-135U/155U programmable controllers comprise a central controller
(CC) and, if required, one or more expansion units (EUs). You need EUs
when there are insufficient slots in the CC for the modules to be used.
Various interface modules (IMs) are available for communication between
the CC and the EUs and between the EUs. It is therefore possible to install an
EU or EUs in the immediate vicinity of the CC (centralized configuration) or
at some distance (distributed configuration). A combination of both types of
configuration is also possible by connecting additional EUs in a centralized
configuration with a distributed EU (see Figure 2-5).
This is clarified on the following pages.

3.1 Principles of Installation of Systems for EMC
What Does EMC
Mean?
Electromagnetic compatibility (EMC) is understood to mean the capability of
electrical equipment to operate correctly in a defined electromagnetic
environment, without being affected by the environment and without
affecting the environment to an unacceptable degree.
All SIMATIC S5 products have been developed for applications in harsh
industrial environments and meet high requirements for EMC. Before
installing the control system, however, you should still carry out EMC
planning and involve possible interference sources in the assessment.
Described in the following chapter are
the various paths over which interference can be picked up in the PLC,
typical interference sources and their coupling mechanisms,
basic rules for ensuring EMC.
3.1.1 Overview of Possible Types of Interference
Electromagnetic interference can be picked up over different paths by the
programmable controller:

Depending on the propagation medium (conducted or non-conducted
interference) and distance from the source, interference can be picked up by
the programmable controller via different coupling mechanisms.
