Note
SINAMICS does not support routing from PROFIBUS to PROFINET and vice versa.
Note
If a CBE20 module fails (e.g. due to a power failure), then communication with the
subsequent nodes is interrupted at this point.

Media redundancy
To increase the availability of PROFINET, you can create a ring topology for redundancy
purposes. If the ring is interrupted at one point, the data paths between the devices are
automatically reconfigured. Following reconfiguration, the devices can once again be
accessed in the resulting new topology.
To create a ring topology with media redundancy, route the two ends of a line-type
PROFINET topology into one device, the SCALANCE device. Closing the linear bus
topology is realized using two ports (ring ports) of the SCALANCE device. The Scalance
