Recommendation: Network components
● Siemens SCALANCE XB005 - as the edge switch for cabling PXC and Desigo room automation stations.
● Siemens SCALANCE XB205 - At the distribution level in the riser zones for setting up VLANs and port
mirroring for diagnostics.
● Siemens SCALANCE XM405 - As core switch for possible IP routing.
SCALANCE switches from the product family X-200 or X-400 support SNMP and can be monitored on
Desigo CC.
IT security and IT basic protection
The elements of infrastructure, IT systems, networks, and applications must be discussed under the
aspects of security and appropriate measures need to be developed. Customer, domestic, or industry
guidelines and directives must be observed under all circumstances.
For additional details, see
IT security on installations with Desigo (CM110663) and Practical Guide on IP
Networks in Building Automation and Control Systems
(CM110668).
Reliability and redundancy
Distribution switches can be cabled on the floor distributors from the core switch in a Gbit ring as
backbone if the customer requires extended availability. To this end, special network components must be
planned on midsized to highly complex networks with basic cabling of fiber optics and copper cable.
