PROFINET interface
Overview
PROFINET devices of the SIMATIC product family have one or more PROFINET interfaces
(Ethernet controller/interface). The PROFINET interfaces have one or more ports (physical
connection options).
In the case of PROFINET interfaces with multiple ports, the devices have an integrated
switch.
PROFINET devices with two ports on one interface allow you to configure the system in line
or ring topology. PROFINET devices with three and more ports on one interface are also
ideal for setting up tree topologies.
Properties and rules for naming the PROFINET interface and its representation in STEP 7
are explained in the following.
Properties
Every PROFINET device on the network is uniquely identified via its PROFINET interface.
For this purpose, each PROFINET interface has:
● A MAC address (factory default)
● An IP address
● A PROFINET device name
