If you do not want to use any of the new features, you can replace the module as follows
without any further configuration:
1. Remove the module to be replaced from the rack.
2. Insert the new module in the rack.
3. Download the configuration data from the PG/PC to the new module.
After downloading the configuration, the CP changes to RUN.
The following table shows you which of the options described above are available with the

General procedure
The configuration data of the CP is stored on the CPU. This makes it possible to replace this
module with a module of the same type (identical article number) without a PG.
Note
Configured MAC address is adopted
When settin
g the ISO protocol, remember that MAC address set previously during
configuration is transferred by the CPU to the new CP module.
For information on replacing previous modules, refer to the information in section
