● Are connected with copper cabling.
● Ensure that Desigo room automation stations from the given floor are located on its own VLAN and
therefore isolated from other Desigo room automation stations on other floors for the purposes of local
BACnet broadcasts.
● You can configure port mirroring of each VLAN for network diagnostics and troubleshooting.
Edge level
Only unmanaged layer 2 switches are planned as edge switches. The following applies:
● Important rooms / Desigo room automation stations are implemented in a star topology on a
distribution switch or remote edge switch.
● Unimportant rooms / Desigo room automation stations (max. 20) are networked in a line topology
(daisy chain).
● Central functions / Desigo room automation stations are implemented using star cabling on a layer 2
switch.
● PXC… for the primary plants and superposed functions in the equipment room are connected in star
cabling on a layer 2 switch.
