Important Information
Purpose of the Manual
This manual supplements the ET 200S Distributed I/O System manual. It
describes all the functions of the IM 151/CPU interface module. The manual does
not deal with general ET 200S functions. You will find descriptions of these in the
ET 200S Distributed I/O System manual (see also the section entitled ”Delivery
Package”).
The information contained in this manual and in the ET 200S Distributed I/O
System manual will enable you to operate the ET 200S with the IM 151/CPU
interface module as a DP slave on the PROFIBUS-DP or in a stand-alone
configuration.
Target Group
The manual describes the hardware of the IM 151/CPU interface module and is
aimed at configuration engineers, commissioning engineers and maintenance
personnel who use the ET 200S with PLC functionality.
It consists of chapters containing instructions and reference chapters.
Delivery Package
This delivery package (order number 6ES7 151-1AA00-8BA0) consists of three
manuals, with contents as follows:

Applicability
This manual is valid for the IM 151/CPU interface module with the order numbers
6ES7 151-7AA00-0AB0 and 6ES7 151-7AB00-0AB0 as well as the components of
the ET 200S specified in the ET 200S Distributed I/O System manual.
This manual contains a description of the components that were valid at the time
the manual was published. We reserve the right to enclose a Product Information
bulletin containing up-to-date information about new components and new versions
of components.
Standards, Certificates and Approvals
The ET 200S distributed I/O system is based on EN 50170, Volume 2, PROFIBUS.
The ET 200S distributed I/O system fulfills the requirements and criteria of
IEC 1131, Part 2 and the requirements for obtaining the CE marking. CSA, UL and
FM certifications have been obtained for the ET 200S.
Shipbuilding certification has been applied for.
You will find detailed information on these standards, certificates and approvals in
the ET 200S Distributed I/O System manual.
Position in the Information Landscape
In addition to the ET 200S manuals, you will also need the manual for the DP
master used and the documentation for the configuration and programming
software used (see the list in Appendix A of the ET 200S Distributed I/O System
manual).
Note
You will find a detailed list of the contents of the ET 200S manuals in Section 1.2
of this manual.
We recommend that you begin by reading this section so as to find out which parts
of which manuals are most relevant to you in helping you to do what you want to
do.
