Block Diagram CAN-Bus
The CAN-Bus is a Multi-Master-Bus which allows the connection of devices. Every bus
user gets a unique address which is set within each bus user.
The usable address range is from 01(16) to 3F(16) (address 00(16) is reserved for
development purposes).
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. This terminating
resistor is set by jumpers, switches or cable bridges on the respective PCB.
A redundant CAN-Bus is provided (CAN1 and CAN2).
The maximum length of a CAN-Bus cabling must not be longer than
400 meter!
