Configuring the Ethernet CP with STEP 7
3.7 Downloading the configuration data to the target system
Procedure
To download the configuration data to the S7 station, follow the steps below:
1. Open the "Set PG/PC Interface" dialog box in the Windows Control Panel.
2. Set the PG/PC interface according to the CPs available on your PG and according to the
bus attachment (interface parameter assignment used).
You will find more detailed information in the integrated help.
3. Change the CPU to STOP mode (regardless of the type of connection - see above).
4. Select the "PLC > Download to Module" menu command
STEP 7 then guides you to the required result in dialog boxes. Note the extra information
in the "STEP 7 User Manual", section "Configuring and assigning parameters to modules"
in /6/;
Disabling the ISO protocol in the configuration (MAC address invisible)
If you disable the use of the ISO protocol in the properties dialog of the Ethernet interface
when configuring the CP, the CP is still accessible via the default MAC address. However,
you can then no longer use any ISO transport connections and you cannot configure any S7
connections via ISO connections. If the ISO protocol is disabled, the configured MAC
address is no longer visible in the properties dialog.
Non-volatile storage of the configuration data (on CPs with data storage)
During the download, you can decide whether or not to download the entire configuration
data or only for selected modules. If you choose to download selectively, you will be
requested to start the download for each module. Select this procedure if you want the
configuration data to be stored in non-volatile storage on the Ethernet CP. To do this, select
the "Copy to ROM" button in the "Download" dialog for the CP.

Note
If you want to download the configuration data via the ISO interface for a CP with an
unchanged, factory-set MAC address and have planned a different MAC address in
the STEP 7 project, you will need to initiate the download in NetPro or HW Config;
only here are you requested to enter the current MAC address. The SIMATIC
Manager, in contrast, aborts the download if the target station is not accessible.
