CAN Bus
CAN Interface
-
The physical interface of CAN interface is according to ISO 11898 and CAN 2.0B protocol
-
The downloading of the PLCopen application can only be done via CAN1
-
All interfaces support bit rates 50, 125, 250, 500, 800, 1000 kbit/s
-
ISOBUS bit rate is 250 kbit/s
-
CAN1 and CAN2 are CANopen compatible and user programmable
-
For safety related communication, CANopen Safety protocol is available for CAN1 and CAN2
-
CANopen and SAE J1939 are available for both CANs. ISOBUS sample point is supported in CAN2
-
11-bit and 29-bit message receive and transmit are supported.
-
Transmitting and receiving remote frames is supported in all CAN interfaces
