Configuration and downloading the configuration data
It is possible to download the configuration data to the CP via MPI or PROFIBUS. The
following version of STEP 7 is required:

Depending on what is available on your PG / PC and the S7-300 station, use one of the following
connectors to load the configuration data: MPI, Industrial Ethernet or PROFIBUS.
Note
Changing bus parameters
If you change the bus parameters in the configuration data, you must not load this
configuration data on the CP via PROFIBUS!
Note
Extensive configuration
Before loading an extensive configuration over a previous configuration, you should run a
memory reset on the CP.
By doing this, you avoid the configuration storage space on the CP being exceeded. If the
configuration storage space on the CP is not adequate, the diagnostics buffer of the CP
reports a lack of resources when you download the configuration data.
Replacing a module without a programming device
The CP supports the option of storing the configuration data of the CP on the CPU. If you
use this option, this means that module replacement is possible without having to load the
configuration data from the PG again.
The configuration data is then stored in load memory of the CPU. Storage of the
configuration data is protected from power failure by the battery backup or the EPROM
module card in the CPU.
