1 Communication via Ethernet CPs in S7 Stations
A-22
S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
1.2.3 Operation Using a Configured or Programmed Database
Configuration and Diagnostics
To connect and configure the Ethernet CP, you require the STEP 7 configuration
software and the SIMATIC NET NCM S7 for Industrial Ethernet option.
NCM S7 for Industrial Ethernet is installed as a STEP 7 option and is therefore
integrated in STEP 7.
NCM S7 for Industrial Ethernet also provides a wide range of diagnostic functions
for the various types of communication.
When configuring PROFInet communication, you also use the engineering tool
SIMATIC iMap; for detailed information on SIMATIC iMap, refer to the manual
Component based Automation - Configuring Plants with SIMATIC iMap /19/.
Programmed Connections
In some situations, it is an advantage to set up communication connections not
over the configuration interface of STEP 7 but program-controlled by specific
applications.
As of STEP 7 V5.2 SP1, a function block is available for these applications that
allows flexible transfer of data blocks with configuration data to an Ethernet CP.
