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 is valid as of version V5.4 SP4 of the STEP 7 software.
Notice
If functions are described that require higher versions, this is indicated by an
additional icon.
Example:
The description of the IT functions is valid for the following modules:
S6GK7 343-1GX30-0XE0: as of hardware version 1,
as of firmware version V1.0
S6GK7 443-1GX20-0XE0: as of hardware version 3,
as of firmware version V2.0
The term “Advanced CP”
The term “Advanced CP” stands for CP modules with E-mail, FTP or Web
functions and PROFINET CBA (for example CP x43-1 Advanced).
Structural innovations in the documentation
SThe chapter “Programmed Communications Connections“ finden is now in the
manual “Functions (FCs) and Function Blocks (FBs) for SIMATIC NET S7 CPs”
/10/.

New Technical Information / Content
Apart from various adaptations to the currently available devices and the current
versioln of STEP 7 / NCM S7 V5.5, the following changes were made:
SIn the Chapter “Configuring Communications Connections”, the information on
unspecified connections as it relates to S7 connections was expanded
SThe previous name “S5−compatible communication” has been replaced by the
name “Open communications services“.
SIn the chapter “CP as Web Server: HTML Process Control” it is taken into
account that S7 applets can only be generated by individual usw of the supplied
S7 beans; the CP does not provide any preprogrammed specifíc S7 applets.
Note
You should also check the History for this manual in Appendix F.
Notice
Please note that the availability of new functions depends on the device type you
are using. You can check which functions your module supports in the description
in the Properties dialog in STEP 7 and in the catalog in HW Config.

1 Communication via Ethernet CPs in S7
Stations
The Ethernet CP for SIMATIC S7 provides a series of communications services for
different tasks.
This chapter explains the following:
SThe types of communication possible with the Ethernet CP on Industrial
Ethernet
SThe tasks handled by the Ethernet CP for the various services
SHow to create the conditions for your communications requirements
You will find further information in the following sources:
SWhen installing the Ethernet CP, follow the instructions in the manual in the
Manual Collection that ships with the Ethernet CP /1/. This also contains further
information about the performance of the Ethernet CP .
SFor the functions and use of the STEP 7 configuration software, some of which
is used to configure the CP (such as hardware configuration), please refer to
/6/.

1.1 Industrial Ethernet
Definition
Within the open, heterogeneous SIMATIC NET communication system, Industrial
Ethernet is the network for the management and cell level. Physically, Industrial
Ethernet is an electrical network that uses a shielded coaxial cable or twisted pair
or an optical network with fiber-optic cables.
Industrial Ethernet is defined by the international standard IEEE 802.3.
All-round communication in the industrial sector
Industrial Ethernet is integrated in the SIMATIC NET concept that allows
comprehensive networking of the management, cell and field levels along with
PROFINET / PROFIBUS and the AS-Interface (AS-i).
