S5-95U, SINEC L2 Preface
How to Use This Manual
The S5-95U programmable controller with SINEC L2 interface can communicate with SIMATIC S5
controllers and other control devices via the SINEC L2 bus system.
To use the SINEC L2 interface to its full capacity, you need detailed information.
This manual contains descriptions for installing and operating the following programmable controllers
as SINEC L2 stations:
• S5-95U, Order No. 6ES5 095-8MB01
• S5-95U, Order No. 6ES5 095-8MB02
The manual does not provide information on the performance of other controllers on the L2 bus.
Only special features of the S5-95U pertaining to data interchange with the CP 5430
communications processor are mentioned.
Experience in configuring and starting up bus-type LANs is helpful, though not necessary, to work
with this manual successfully.
This section is intended to make it easier for you to use the manual.
Contents of This Manual
• Chapter 1
This chapter provides an overview of the applications, performance capabilities, operation
principle, basic terminology, and transmission physics of the SINEC L2 bus system. This
chapter characterizes the possible types of data transmission and specifies and explains the
selection criteria for special applications.
• Chapter 2
This chapter specifies the installation procedures that you should follow to ensure that your
S5-95U controller functions properly as a station on the SINEC L2 bus.
• Chapter 3
This chapter summarizes information that you need to start up your S5-95U controller as a
station on the SINEC L2 bus. You will also discover how to recognize faults in the controller and
find out what tests and diagnostics are available to you.
• Chapters 4, 5, 6, 7 and 8
These chapters use examples to describe the various types of data transmission in detail.
• Chapter 9
This chapter shows you how to implement programmer functions over the LAN.
• Appendices
The appendices contain two types of information. On the one hand, you will find brief
information for regular use (e.g., all the DB1 parameters); on the other hand, you will find
additional information of interest to network experts (e.g., concerning the SAPs).
Each chapter begins with a brief explanation of its contents. By reading the first section of a
chapter, you can determine whether the information in the chapter is important to you.
