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.
Result
After downloading the configuration, the CP changes to RUN.
The following table shows you which of the options described above are available with the

Replacing a module without a programming device
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.
