3.3 Configuring an IO device through hardware detection
PROFINET with STEP 7 V15
Function Manual, 12/2017, A5E03444486-AH

Result of the hardware detection
If the hardware detection is successful, STEP 7 inserts the IO device with all the modules
and submodules into the project.
An IO device configured via hardware detection responds as follows:
● Modules configured through the "Hardware detection" are configured as if they have been
inserted from the catalog.
● MAC address: STEP 7 imports the MAC address of the detected IO device into the
project.
● IP settings:
– If the detected IO device already has an IP address, STEP 7 imports the IP address
into the project.
– If the detected IO device does not have an IP address, STEP 7 automatically assigns
an IP address in the project.
PROFINET device name:
– If the detected IO device already has a PROFINET device name, STEP 7 imports the
PROFINET device name into the project.
– If the detected IO device does not have a PROFINET device name, STEP 7
automatically assigns a PROFINET device name in the project.
● IO devices configured through "Hardware detection" have neither an IP subnet nor an IO
controller assigned.
