NOTICE
Backing up the configuration
Before replacing a module, save the configuration stored on the communications module so
that you can transfer it to the newly connected communications module after replacing the
module.
NOTICE
Loading a configuration
Note that you cannot use the configuration file to transfer user profiles and passwords to
other communications modules. After loading the configuration file into a new
communications module, you may need to enable user management and create new user
profiles and passwords.
The following options are available for saving the current configuration of the
communications module and restoring it to the newly connected communications module
after module replacement:
• On the controller
• Using the TIA Portal (STEP 7 Basic / Professional) in a STEP 7 project
• Using the WBM on your PC
These alternative methods are described below.
