Siemens SIMATIC NET S7-300 User Manual

3 Operating the Ethernet CP with
A-88
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
Procedure
To download the configuration data to the S7 station, follow the steps outlined
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).
For more detailed information, refer to the integrated help system.
3. Change the CPU to the STOP mode (regardless of the type of interface - see
above).
4. Select the menu command PLC
"
Download to Module.
STEP 7 then guides you through dialog boxes. Note the additional information in
the “STEP 7 User Manual”, Chapter “Configuring and Assigning Parameters to
Modules” /6/.
Deactivating the MAC Address in the Configuration
If you deactivate the use of the MAC address when you are configuring the CP, the
CP can be reached via the preset MAC address, however you cannot define any
ISO transport connections or S7 connections over ISO connections in your
configuration.
Non-volatile storage of the project engineering data (on CPs with data
management)
You can download the configuration data step-by-step or all at once. If you
download step-by-step, you will be prompted to start the download function
separately for each module. You must select this method if you want to save the
configuration data in non-volatile memory on the Ethernet CP. In this case, select
the “Copy to ROM” button in the “Download” dialog for the CP.
Downloading the Configured Connections
To download configured connections, you use a corresponding download function
in the connection configuration (NetPro).
Notice
If you have assigned a new address to the Ethernet CP or have configured
connections, you must always download the connection configuration again.
Remember that you also make suitable address adaptations for the other stations
or “substitute objects”.
