can be increased up to 250 by connecting several CAN bus systems. This
limitation of exactly 250 devices results from the addressing scheme used
by the CAN bus. The addressing scheme allows the allocation of a maxi-
mum of 250 different CAN device addresses.
• Improvement of signal quality
With CAN bus systems, whose bus length exceeds 1000 meters, a CAN
bus repeater should be used. The CAN bus repeater accomplishes a signal
processing and a reinforcement of the bus signals. The internal running
time of the repeaters of approx. 150 ns corresponds to an extension of the
bus over approx. 45 meters.
• Creation of alternative network topologies
By using one or several repeaters, not only the above-mentioned bus topo-
logy, but the creation of other network topologies are also possible.
