The connection station from the FCnet/SAFEDLINK sub-net to the FCnet/Ethernet
sub-net is a router station. This station has the function of a router and addresses
the ↑ stations on the FCnet/Ethernet sub-net.
Characteristics
FCnet/Ethernet sub-nets on the FCnet/SAFEDLINK
network
Max. 1
Networkable stations via FCnet/Ethernet
Max. 14 (incl. router
station)
Stations that can be networked in both sub-networks Max. 32
8.9 Extended networking
↑ Extended networking is the merging of several ↑ SAFEDLINK sub-nets via
FCnet/LAN, which is managed as optical Ethernet in loop topology via the Ethernet
switch (modular) FN2012.
The sub-nets communicate via the ↑ router stations.
Malfunctions during a partial upgrade
Ethernet switch (modular) FN2012 is not compatible with Ethernet switch (MM)
FN2008 and so may only be used in panels ≥MP6.
A
↑
router station has an integrated Ethernet switch (modular) and is configured
as a router station with 'SintesoWorks'.
In
↑
extended
networking, no additional Ethernet sub
-
net may be connected in a
SAFEDLINK sub-net.
Properties
● Structure of large and efficient networks
● Merging of several ↑ SAFEDLINK sub-nets
● High data rate and not sensitive to electric interference (fiber optic cables)
● Redundant network topology (loop-shaped networking)
● Redundant networking of sub-nets possible (complies with EN 54)
8.9.1 Redundant networking
A sub-net is networked redundantly by connecting the sub-net to the FCnet/LAN
via two ↑ router stations. This networking type is specified according to EN 54 in
the following cases:
● A total of more than 512 FDnet devices in the sub-net
● Central remote transmission in the sub-network
● The monitored surface in the sub-net is greater than 12,000 m
