8.7 Networking via Ethernet
↑ Stations can be networked via Ethernet. In this case, the connection is
established with a commercially available Fast Ethernet cable (CAT5 or CAT6).
Restrictions on the Ethernet:
● The networking is not in compliance with EN 54 (no degraded mode possible)
● No redundant networking possibilities
● A maximum of 32 stations can be networked with
– Additional stations can be networked via FCnet/SAFEDLINK

If only two stations are to be networked, the connection is established directly with
one crossed Fast Ethernet cable.
Ethernet networking of several ↑ stations
If more than two stations are to be networked via Ethernet, they must be connected
to each other via a hub or a switch.
A router must not be used for Ethernet networking, i.e. all stations must be in the
same IP sub-network.
