NOTE: If the HEX switch setting is changed, the Panel
Bus I/O module will revert to its default
configuration. With L
the HEX switch is without function.

Setting the I/O Bus Switch

L W Bus Topologies
ON ORKS
The L W Bus is a 78-kilobit serial link that uses
ON ORKS
transformer isolation so that the bus wiring does not have a
polarity. I.e. it is not important which of the two L
Bus terminals are connected to each wire of the twisted pair.
The L W Bus does not need to be shielded on the
ON ORKS
controller module side.
The L W Bus can be wired in daisy chain, star, loop or
ON ORKS
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
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.
