7.6.1.6 Communication channels for PROFINET
CUD with CBE20 Communication Board Ethernet
A Communication Board can be optionally inserted in the CUD:
● The CBE20 Communication Board is a PROFINET switch with four PROFINET ports.
Notes
Note
Ring topology
When conne
cting the ports, it must be ensured that for standard applications a ring topology
is not created. Additional information on ring topologies can be found in Chapter "
Media
(Page 270)".
Note
Support for the medium-dependent interface auto-MDI(X)
•
The CBE20 Communication Board also supports auto-MDI(X). It is therefore possible to
use both crossover and straight through cables to connect the devices.
