Replacing older modules: CPs with configurable data management 
Other older modules (GX11) can be replaced in different ways depending on the type of data 
management: 
Data management on the CPU: Replacing a device 
Here, it is not necessary to adapt or download the configuration data; the new module 
behaves identically in every way to the replaced module. 
This variant is only possible if the originally used CP was configured for data maintenance on 
the CPU (option "Module replacement without PG"). Follow the steps below: 
1.  Remove the module to be replaced from the rack. 
2.  Insert the new module in the rack. 
Data management on the CP: Module replacement with download 
The module must be supplied with the existing or adapted configuration data. 
These variants are necessary when the originally used CP was configured without the option 
"Module replacement without PG", in other words, with data management on the CP. 
● 
Adapting the STEP 7 project (preferred solution) 
If you adopt the configuration data unchanged and therefore leave the data management 
on the CP, do not use the option of data storage protected from power down with the new 
CP. For this reason, we recommend that whenever possible you adapt the existing 
configuration to the new CP type: 
1.  Replace the old module with the new module in the rack. 
2.  In STEP 7, replace the already configured CP with the new module; You will find this in 
the hardware catalog. 
As soon as you take the new module from the catalog in HW Config and drag it to the 
module you are replacing, the configured connections and data are adopted. 
The mode is then automatically configured as "data management on the CPU". 
3.  Save and compile the project. 
4.  Download the configuration data to the target system again.

: STEP 7 project unchanged 
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.
