 Bus Topologies 
The L
ON
W
ORKS
 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
ON
W
ORKS
 
Bus terminals are connected to each wire of the twisted pair. 
The L
ON
W
ORKS
 Bus does not need to be shielded on the 
controller module side. 
The L
ON
W
ORKS
 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

W
ORKS
 Bus 
lengths, and its simple structure presents the least number of 
possible problems, particularly when adding on to an existing 
bus. 
 
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.

  WARNING 
Risk of electric shock or equipment damage! 
► 
Do not touch any live parts in the cabinet. 
► 
Disconnect the power supply before you start to install the 
Excel 800 System.  
More than one disconnect switch may be required to de-
energize the system. 
► 
Do not reconnect the power supply until you have 
completed the installation.  
 
NOTE: 
The terminal socket of each I/O module can be 
mounted and wired before inserting and locking 
the corresponding electronic module.
