Compared to the previous edition of this manual, Distributed I/O System DP/

ASi Link having the Order No. 6ES7 156-0AA00-8AA0, Edition 2, the fol-

lowing changes have been incorporated:

DP/ASi link to S7

diagnostics during operation with an S7/M7 DP master

The DP/ASi link meets the requirements and criteria of the following stan-

dards and approvals:

IEC 1131, Part 2

EN 50170 Volume 2, PROFIBUS

ASi: Actuator Sensor Interface Complete Specification

CE mark requirements

CSA, UL and FM approvals

You will find complete details of approvals and standards in appendixA.1.

This manual, DP/ASi Link, describes the DP/ASi link and the installation of

the ASi.

The description of the PROFIBUS-DP and a master interface such as

IM 308-C do not form a part of this manual. You will find further information

on these subjects in the manual called Distributed I/O System ET 200, Order

No. 6ES5 998-3ES12.

The Distributed I/O System DP/ASi Link can be acquired on a CD-ROM as

an electronic manual.

You can quickly access specific information in the manual using the follow-

ing access aids:

At the beginning of the manual, you will find a complete list of manual

contents and lists of illustrations and tables contained in the whole docu-

ment.

Within the chapters, you will find information in the left-hand margin

giving you an overview of the subject that is dealt with.

Following the appendices, there is a glossary in which technical terms

used in the manual are defined.

At the end of the manual, you will find a comprehensive index enabling

rapid access to the information you require.
