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 LONWORKS
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 LONWORKS Bus can be wired in daisy chain, star, loop
or any combination thereof as long as the maximum 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 because uncontrollable line
reflections may occur.
Instead of LION Controllers, other C-Bus controllers (e.g.,
the Excel 500, Excel 100, PANTHER) can also be
connected.
