Addressing CAN bus nodes
The MOBILE devices can be operated via the following CAN bus systems:
ƒ
Public CAN: Communication with vehicle or subsystem control (e.g. air conditioning
system).
– The Public CAN is the customer interface provided for applications in commercial
vehicles which can be adapted to the respective communication and diagnostic
environments of the single OEM´s. By default, the control is carried out according
to SAE J1939 and the diagnostics is carried out according to UDS (Unified
Diagnostic Services) which is implemented in the Application Controller (AppC).
– The Public CAN is implemented twice on X31. This enables a simple looping
through (daisy chain).
– The bus terminating resistor is integrated in X31.
ƒ
Private CAN: Communication with subsystem or other drives.
– The Application Controller (AppC) and the Motor Controller (MC) are connected via
the Private CAN (CAN2.0A) and communicate in accordance with CANopen, Drive
Profile DS 402. This Private CAN interface enables the Application Controller to
transmit the control commands received via the Public CAN to the Motor
Controller(s).
– The Private CAN must be completed with an external bus terminating resistor.
