7.6.5 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.
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.

Note
All communication profiles are saved on the memory card. Some communication profiles
(UFW files) can also be saved to the flash memory in the d
evice itself. In this case, the
memory card does not have
to be inserted.
p8835=1 (PROFINET): The memory card does not have to be inserted.
p8835 = 3 (SINAMICS Link): The memory card must remain inserted.
p8835 = 4 (EtherNet/IP): The memory card does not h
ave to be inserted.
p8835 = 5 (Modbus TCP): Memory card m
ust remain inserted.
Identification of the firmware version
Using parameter r8858, the loaded firmware version of the PROFINET interface can be
uniquely identified.
