10.3.3

Hardware configuration (configuring SINAMICS drives with PROFINET)

Communication Board Ethernet CBE20
The CBE20 option module is inserted in the option slot of the CUD. The CBE20 is equipped
with a PROFINET interface with 4 ports that can be used to connect the PROFINET
subnetwork.
Note
The ports must not be interconnected in such a way that a ring topology is created.
Operation in PROFINET IO networks
A SINAMICS DCM with CBE20 can be integrated into PROFINET IO networks in all
transmission modes
Note
SINAMICS DCM only supports Version V2.2 (IRTflex) for data transfer type IRT.
A SINAMICS DCM with CBE20 can only act as a synchronization slave within a PROFINET
IO network.
● CBE20 module is plugged into CUD:
● CBE20 module is not inserted but configured:
Telegrams

– The cyclic DP interface is disabled.
– Transmission type RT is configured. The SINAMICS DC MASTER uses a local clock
cycle.
– Transmission type IRT (option "not isochronous") has been configured: The CBE20
synchronizes itself with the send clock and operates as isochronous switch. The
SINAMICS DCM uses a local clock cycle.
– Alarm A1487 "Topology fault" is present. Access via PROFINET is not available.
There is no data exchange via PROFINET. The SINAMICS DCM uses a local clock
cycle.
