System updates and firmware updates are retained when the CPU is reset to factory settings.
If there was a SIMATIC Memory Card inserted in the CPU prior to the reset to factory settings,
the CPU downloads the configuration on the SIMATIC Memory Card (hardware and software).
A configured IP address is then valid again.
Note
Password for protection of confidential configuration data
The password for protection of confidential configuration data is retained after the CPU is
reset to factory settings. The password is only deleted when the "Delete password for
protection of confidential PLC configuration data" option is set in STEP 7.
You can find additional information on the password for protection of confidential
