CAN bus system overview

The basic version of the -MASTER/SLAVE- technology includes as the smallest solution the
-MASTER 2.0- System Control for water exchanging measures in the sector of drinking water and
for signal evaluation.
Furthermore, the -MASTER 2.0- System Control, using two integrated CAN bus connections, can
trigger up to 62 -SLAVE- controls and one directly-connected KHS water exchange group. Up to a
maximum of 31 -SLAVE- controls per CAN-BUS connection of the -MASTER 2.0- can be controlled
per CAN bus connection.
That means up to 63 KHS water exchange groups can be connected and operated through
the -MASTER/SLAVE- technology. The accumulated total length of one CAN bus connection
can amount to a maximum of 1000 m (total length is thus 2000m).

Layout variants

Note:
The controllers must be connected in series, as can be seen in Example 1.
During this, the -MASTER 2.0- System Control can be connected within the
series (Variant 2) or as a final subscriber (Variant 1). Branches or start
connections, as can be seen in Example 2, are not possible. Furthermore, shorter
cable distances are recommended.
