manual, you should be familiar with the manual ‘AS-Interface Introduction and Basic Information’.

We recommend the following procedure when...

...You want a general overview of the

AS-Interface.

´

Read the manual ‘AS-Interface

Introduction and Basic Information'.

This manual contains general

information about the AS-Interface,

generally referred to as AS-i in this

manual.

...You want to install and start up the CP

142-2.

1.1 General

1.1.1 Overview of the Chapters

Chapter 1 Introduction

This chapter explains how to make the best use of the manual.

Chapter 2 Technical Description and Installation Guidelinesn

Chapter 2 provides you with an overview of the modes, installation and startup and the indicators and

operator controls of the CP 142-2.

Chapter 3 Standard Operation of the CP 142-2

Chapter 3 describes how to operate the CP 142-2 in the ET 200X distributed I/O system in standard

operation.

Chapter 4 CP 142-2 Extended Operation with FC “ASI_3422”

Chapter 4 describes the extended operation of the CP 142-2, that requires the

FC “ASI_3422” in the control program. In this type of operation, the AS-i slaves can be assigned

parameters or the slave addresses can be modified by the S7 program.

This mode is only possible with the BM147.

Chapter 5 Replacing a Defective Slave / Automatic Address Programming

Chapter 5 explains how to replace a failed AS-i slave quickly and simply.

Chapter 6 Error Indicators on the CP 142-2 / Dealing with Errors

This chapter explains the possible error indications on the CP 142-2 and explains how to deal with

them.

Chapter 7 PROFIBUS DP Configuration When Using the BM141/BM142

Chapter 7 contains additional information about DP configuration of the BM141/BM142.
