SIMATIC NET NCM S7 for Industrial Ethernet

Release 6/2003

C79000–G8976–C129–07

The configuration data of the Ethernet CP are downloaded from the hardware
configuration. All the configuration data of the S7 station are downloaded including
the central configuration, all relevant DP master systems and all parameter
settings.

The data of the configured connections must also be downloaded, see below.

You can download the configuration data to the S7 station on the following paths
(interfaces):

S

MPI interface

You can use this interface to download configuration data or when assigning a
MAC/IP address for the first time (node initialization  – for details, refer to the
manual /1/ “Assigning Addresses for the First Time”).

S

Industrial Ethernet

Here, you use the PG mode of the Ethernet CP in the S7 station (see also
Section 1.3).

Depending on the PG/PC interface used by the station on which you create
your configuration, you can download the defined configuration data to the S7
station over the TCP/IP interface or over the ISO interface of STEP 7.

– When you download over the IP interface, the CP must already have been

assigned an IP address; refer to Chapter 2.3.

– When you download over the ISO interface, you can use the preset MAC

address. However, please note the following:

If you want to download the configuration data over the ISO interface to a CP with
an unchanged, factory-set MAC address and you have configured a different MAC
address in your STEP 7 project, you must start the download in NetPro or HW
Config; this is the only way you will be prompted to enter the current MAC
address. The SIMATIC Manager, on the other hand, aborts the download if the
target station cannot be reached.
