CP 523 Preface

Preface

This manual is a revised, updated edition of the original CP 523 manual. The revision was necessary

because the CP 523 has been equipped with an additional communication control procedure, thus

upgrading the number of transmission modes in ”Communications mode” from two to three:

• Transparent mode

• Interpretive mode

• 3964(R) mode (

new

)

The characteristics of each mode are discussed in Section 2.3.2.

The CP 523 is a powerful I/O module which can be used in the S5-115U, S5-135U, S5-150U, S5-155U

and S5-115F programmable controllers. In order to make best use of the serial I/O module, you

require comprehensive information. For this reason, the CP 523 serial I/O module has its own

manual dealing only with those facts and examples that are relevant to the module. Demands for

a higher quality of technical documentation have also been met, which means

• Standardization of terminology and notation

• More detailed breakdown of subjects

• Illustration of individual problems

• User-friendly arrangement of the contents

The aim is that both users with little previous experience and SIMATIC S5 experts should find all

the information that they require to work with the CP 523.

However, the applications are so numerous that not all the problems that might occur can be dealt

with in one manual. For other problems, please ask your Siemens representative for advice.

CP 523 Introduction

Introduction

It is important to study the introduction carefully before reading the rest of the manual. This will

help you to use the manual and will save you time.

Description of Contents

This manual is a comprehensive description of the CP 523. The manual can be divided into blocks

according to topics.

• Description

- The "System Overview" contains information on the tasks the module can perform and on

how the module is used in the S5-115U, S5-135U, S5-150U, S5-155U and S5-115F.

- The "Technical Description" contains general information on the principle of operation of

the module, technical specifications, details of the serial interface and input/output (I/O)

modules and a list of accessories.

• Installation and operation

- The chapter on "Hardware Installation" tells you which programmable controllers and

expansion units the module can be used with, how it is assembled and how to connect it to

a printer or I/O module (connector pin assignments and terminal diagrams).

- "Notes on Operation" describes the restart characteristics and actual operation. This

chapter also contains the error messages that can occur during startup.

• Addressing

This chapter demonstrates how to address the module and describes the function of the

transfer memory.

• Functional description

We have devoted a separate chapter to the "Print mode" and the "Communications mode".

Each of these chapters contains the information necessary for programming the module for

the relevant mode. This saves you time-consuming searches in the manual.

• Appendix A: Summary

All the information you require to operate the CP 523 has been gathered together here in list

form. This has been designed for those users who have read the manual and wish to find some

brief item of information quickly.

Introduction CP 523

Conventions

In order to improve the readability of the manual, a menu-style breakdown has been used, i.e.:

• The individual chapters can be quickly located by means of a thumb register.

• There is an overview containing the headings of the individual chapters at the beginning of

the manual.

• Each chapter is preceded by a breakdown of its subject matter.

The individual chapters are subdivided into sections and subsections. Boldface type is used for

further subdivisions.

• Pages, figures and tables are numbered separately in each chapter. The page following the

chapter breakdown contains a list of the figures and tables appearing in that particular

chapter.

Certain conventions were observed when writing the manual. These are explained below.

• A number of abbreviations have been used.

Example: Central processing unit (CPU)

• Footnotes are identified by superscripts consisting of a small digit (e.g. ”1”), or ”*”. The actual

footnote is generally at the bottom left of the page or below the relevant table or figure.

• Cross-references are shown as follows:

”( 7.3.2)" refers to subsection 7.3.2.

No references are made to individual pages.

• All dimensions in drawings etc. are given in millimetres/inches (mm/in.).

• Information of particular importance is framed in

grey-bordered rectangles.

• All program examples have been generated in statement list form and always refer to the

same slot.

• All data in connection with the programmer refers to the German version of the PG 685. The

relevant user manual contains a detailed description of programming procedures with this

programmer.

• The ”Reader's Note” in Section 7 provides references to various subsections, thus making it

easier to find the subsections relevant to your application or specific requirements.

Manuals can only describe the current version of the device or unit. Should modifications or sup-

plements become necessary in the course of time, a supplement will be prepared and included in

the manual the next time it is revised. The relevant version or edition of the manual appears on

the cover. The present manual is edition "1". In the event of a revision, the edition number will be

incremented by "1".

At the end of the manual you will find correction forms. Please enter in these forms any

suggestions you may have in the way of improvements or corrections and send them to us. Your

comments will help us to improve the next edition.

Convention Definition Example

A box that indicates a type of hazard,

describes its implications, and tells you

how to avoid the hazard is a cautionary

statement. Some cautionary statements

include a graphic symbol representing

an electrical or radio-frequency hazard.

All cautionary statements have one of

the following levels of caution:

• A danger indicates that loss of

life, severe personal injury, or

substantial property damage

will result if proper precautions

are not taken.

• A warning indicates that loss of

life, severe personal injury, or

substantial property damage

can result if proper precautions

are not taken.

• A caution indicates that minor

personal injury or property

damage can result if proper

precautions are not taken.
