Notes on Using this Manual and on the CE Symbol
How the Manual is
Organized
1-2
Pointers on how this manual is organized are given as a guide below. 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. The
technical features, installation, startup and maintenance of the CC are
described here. 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. The
technical features, installation and startup of the individual CPUs are
described here. 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.
The installation, wiring and operation of these modules are described
here. 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.
Chapter 4, Section 4.2, describes 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.
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. Sections 6.5 and 6.6 describe the 923C and 923A coordinators.
