7.4 Replacing older modules: CPs with configurable data management
CP 443-1 (EX30)
66 Manual, 03/2019, C79000-G8976-C255-05
Note
Replacing modules with IT functions
In principle, you can also replace predecessor modules with IT functionality with
a CP 443-1
EX30. The IT functionality is then, however, not supported!
When operating the CP with CPUs of version V4.x, all functions are supported that were
provided by the CP 443-1 EX11. Operation as PROFINET IO controller and SEND/RECV
connections in the SPEED SEND/RECV mode are not supported.
Replacing older modules: CPs with configurable data management
Other older modules (EX11) 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 available 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".
