3.1 How to Commission an Ethernet CP
The essential steps in commissioning an Ethernet CP are shown in the following
overview:
Notice
The chart below shows the basic steps. Please read the device-specific
instructions in “Installation and Commissioning” in the description of your CP
(Manual Part B).
Install the CP on the S7 standard rail
(S7-300) or in the S7 rack (S7-400).
Connect the power supply.
Connect the CP to Industrial Ethernet.
Install the STEP 7 configuration
software on a PG/PC.
Configure the Ethernet CP:
 by configuring in the
project engineering
see Section 3.3
or
 by programming
see Section6
Turn on the S7 station.
Download the configuration data and the user programs to
