Preface

Purpose

This manual supports you when using the communication services provided by the

SIMATIC NET communications processors (Industrial Ethernet CPs) for

communication on SIMATIC NET with Industrial Ethernet in the management and

cell areas.

The manual contains information about the following topics:

The performance and areas of application of the communication services

Configuring the CP with the NCM S7 configuration software

Programming the communication interfaces to the user program

Audience

This manual is intended for personnel responsible for installing and programming

STEP 7 programs and for service personnel.

Scope of this Manual

This manual applies to version 5.1 and higher of the NCM S7 configuration

software and to version 5.1 and higher of the STEP 7 software.

This version of the manual includes information relating to new functions in STEP 7

and NCM S7 as of V5.1 Service Pack 3.

In the main, this involves the following topics:

Configuring multicast and broadcast on UDP connections.

See Section 4.

The blocks AG_SEND and AG_RECV can now be used for “long data packets”

with an S7–300. See Section 5.

The S7 CPs for Ind. Ethernet are now supplied with a default MAC address

allowing configuration data to be downloaded over Ethernet without a ”node

initialization”.
