3.3 Configuring an IO device through hardware detection
PROFINET with STEP 7

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.
