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.
