Configuring the PROFINET communication with STEP 7

A.3.2.1

Communication via PROFINET - example

Profinet network in a line topology
The adjacent example shows
the structure of a Profinet
network in a line topology,
with one controller (S7-300),
three devices (G120
converters) and one
supervisor (programming
device).
Communication is established
via "twisted-pair lines" with
RJ45 connectors. 100 Mbit/s
in the full duplex mode is
required as transmission rate.
A.3.2.2

Configuring the system in HW Config

Open HW Config in STEP 7 via "Insert/[Station]", and create the components in accordance
with your hardware structure. The following example is limited to the components that are
absolutely required.
Insert the CPU if you have configured your station with a rack and power supply.
NOTICE
Device name for PROFINET
Based on the device name, when booting, the PROFINET controller assigns the IP
address; as a consequence, the device names within a subnet must be unique.
In the SIMATIC Manager, only lower-case letters may be used for the device name. Spaces
and special characters are replaced by "x".
