Device name and IP address

Introduction
In order that the PROFINET device can be addressed as node on PROFINET, the following
are required:
● A unique PROFINET device name
● A unique IP address in the relevant IP subnet
STEP 7 assigns a device name during the arrangement of a PROFINET device in the
hardware and network editor. The IP addresses are typically assigned automatically by
STEP 7 and assigned to the devices based on the device name.
You can change the name and IP address manually.
In STEP 7
You can find the device name and the IP address under "Ethernet addresses" in the
properties of the PROFINET interface in the Inspector window.
