CAN bus
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
(16)
to 3F
(16)
(address 00
(16)
is reserved for development pur-
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 set by jumpers or switches on the re-
spective PCB.
The Can bus is achieved redundant (CAN1 and
CAN2).
Note:
The maximum length of a CAN--bus cabling must
not be longer than 300 meter!
