7.5 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.
● Variant A: 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.
● Variant B: 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.
