3 Operating the Ethernet CP with
STEP 7/NCM S7
To attach a SIMATIC station to Industrial Ethernet via the Ethernet CP, configure
the CP with the NCM S7 configuration software. The chapter explains the
following:
 How the CP is configured in the STEP 7 project
 How the various network configurations are managed (setting up access to
other systems)
 How to control and supply the CP with data using NCM S7
You will find further information in the following sources:
 When installing the Ethernet CP, please read the instructions in the
device-specific Part B of this manual. This also contains further information
about the performance of the Ethernet CP .
 For more information about the functions and applications of STEP 7 in which
