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 setting the ISO protocol, remember that MAC address set previously during
configuration is transferred by the CPU to the new CP module.

Retentivity of data management on the CP:
IP address retained after cycling power; this makes
downloading and diagnostics possible using the existing IP
address.
The IT functionality available on the new CP corresponds to the
range of functions of the predecessor module.
If you want to use the new IT functions of the GX30, you will
need to change the configuration with the necessary STEP 7
version.
