How to Use This Manual
If you are a first-time (novice) user of S7-200 Micro PLCs, you should read the
entire S7-200 Programmable Controller System Manual . If you are an experienced
user, refer to the manual table of contents or index to find specific information.
The S7-200 Programmable Controller System Manual is organized according to
the following topics:
"Introducing the S7-200 Micro PLC" (Chapter 1) provides an overview of some
of the features of the equipment.
"Installing an S7-200 Micro PLC" (Chapter 2) provides procedures, dimensions,
and basic guidelines for installing the S7-200 CPU modules and expansion I/O
modules.
"Getting Started with an S7-200 Programming System" (Chapter 3) describes
how to set up an S7-200 programming system.
"Basic Concepts for Programming an S7-200 CPU" (Chapter 4), "CPU Memory:
Data Types and Addressing Modes" (Chapter 5), and "CPU and Input/Output
Control" (Chapter 6) provide information about how the S7-200 CPU processes
data and executes your program.
"Setting Up Communications Hardware and Network Communications"
(Chapter 7) provides information about how to install and remove
communications hardware and how to connect the S7-200 CPU to different
types of networks.
"Conventions for S7-200 Instructions" (Chapter 8) provides an overview of the
different programming language concepts and terminology.
"SIMATIC Instructions" (Chapter 9) provides descriptions and examples of
SIMATIC LAD, FBD, and STL programming instructions.
"IEC 11313 Instructions" (Chapter 10) provides descriptions and examples of
IEC 11313 LAD and FBD programming instructions.
"Using USS Protocol Instructions to Communicate with Drives" (Chapter 11)
provides descriptions and examples of USS Protocol Instructions and
information about how to use these instructions to communicate with drives.
Additional information (such as the equipment specifications, error code
descriptions, troubleshooting, and STL instruction execution times) are provided in
the appendices.
