LONWORKS Bus Topologies
The LONWORKS Bus is a 78-kilobit serial link that uses
transformer isolation so that the bus wiring does not have a
polarity. I.e. it is not important which of the two L
ONWORKS
Bus terminals are connected to each wire of the twisted pair.
The L
ONWORKS Bus does not need to be shielded on the
controller module side.
The L
ONWORKS Bus can be wired in daisy chain, star, loop
or any combination thereof as long as the max. wire length
requirements are met.
Configuration
The recommended configuration is a daisy chain with two
bus terminations. This layout allows for max. L
ONWORKS
Bus lengths, and its simple structure presents the least
number of possible problems, particularly when adding on to
an existing bus.
See also “L
ONWORKS Mechanisms”, Product Literature no.:
EN0B-0270GE51.
C-Bus Topologies
Via the C-Bus up to 30 C-Bus devices (e.g., controllers, etc.)
can communicate with one another and a PC central. The
C-Bus must be connected via the individual controllers
(open ring).
NOTE: Star connection is not allowed as this might
cause uncontrollable line reflections.
Instead of LION Controllers, other C-Bus controllers (e.g.,
the Excel 500, Excel 100, PANTHER) can also be
connected.
