S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
New in release 03 / STEP 7 V5.3 SP3 (C79000 -G8976 -C182 -03)
Apart from various adaptations to the currently supplied devices and the current
version of STEP 7/NCM S7 V5.3 SP2/SP3, the following features were included:
 New blocks for user programs
- There is a new block FC10 AG_CNTRL available for the SEND/RECEIVE
interface
- There are also detailed sample programs for the SEND/RECEIVE interface
on the Web. You will also find the link in Section 7.
 Expanded sample of programmed communication connections in Section 6.
 Printed version - General Part A and Device Description Part B separate
Due to the increasing size, the printed version has been divided into two
volumes.
New in release 01 / STEP 7 V5.3 SP0 (C79000 -G8976 -C182 -01)
 New structure of the manual
In this release we have put together the previously separate manuals NCM S7
and S7 CPs in one manual.
This also takes into account that the NCM S7 configuration tool is no longer
installed separately for PROFIBUS and Industrial Ethernet. The functions of
NCM S7 are now installed automatically when STEP 7 is installed.
 Range of devices described: S7 CPs and gateways
The devices described in detail in Part B now include not only the CPs for
SIMATIC S7 but also the gateway IE/PB Link. This step was taken in particular
due to the special significance for PROFINET applications.
New in release 07 / STEP 7 V5.2 SP1 (C79000-G8976-C129-07)
Note
This is the last release before the two manuals “NCM S7 for Ind. Ethernet” and
“Device Manual S7-CPs for Ind. Ethernet” were merged.
This manual also includes specially marked passages that apply specifically to and
require version 5.2 SP1 of the NCM S7for Industrial Ethernet configuration
software and version 5.2 SP1 of the STEP 7 software.
These include new functions for IP configuration:
 IP Access Protection
Using IP access protection gives you the opportunity of restricting access to the
local S7 station to partners with specific IP addresses.
 Configuring connections from the user program
