The CAN bus is a Multi-Master-Bus allowing the
connection of all devices and systems regardless
of their task and function. This means that any
number of devices can be connected. These de-
vices must be designed for CAN bus technology.
For the CAN bus it is essential that every bus user
is addressable via a unique address. This address
is set within each bus user.
The usable address range is from 01
(address 00
(16)
poses).
Each bus user can send and receive data via the
CAN bus.
The CAN bus must be terminated at both ends via
an ohmic resistor (125 Ohms). This terminating
resistor is activated by a jumper or a switch (E10)
on the respective PCB.
There are 2 redundant bus systems (CAN1 and
CAN2).
Note:
The total length of CAN bus cable should not ex-
ceed 300m.
