Communication with CBE20

The CBE20 is a Communication Board that can be flexibly used and which can be operated
with different communication profiles. Only one firmware of a communication profile can be
loaded at any one time. The available firmware files are saved with the communication
profiles in UFW files on the Control Unit memory card. Firmware can only be selected prior
to commissioning.
The required file is selected using parameter p8835. A POWER ON must be carried out after
selecting the desired UFW file. During the subsequent system boot, the corresponding UFW
file is loaded. The new selection then becomes active.
