In CAN1, it is possible to connect the internal termination resistor. For more information refer to section System topologies.
Codesys 2.3 IDE communication is supported for CAN1.
Higher layer protocol is user programmable (CAN1, CAN2, CAN3, CAN4) communication
The physical interface of CAN is according to ISO 11898 and CAN 2.0B protocol
The PLCopen application can be downloaded via CAN1.
All interfaces support bit rates 10, 20, 50, 125, 250, 500, 800, 1000 kbit/s
All interfaces can be configured as listen only mode. An exception is CAN1, which is in boot up normal mode because it is used for Codesys communication.
11-bit and 29-bit message receive and transmit are supported.
Transmitting of remote frames is supported in all CAN interfaces.
Support for receiving one remote frame is supported. This is received for the control unit's own node guard functionality.
This product contains 4 CANs for the CAN bus connection. CAN1 has duplicated pins, so it can be easily used for chaining the control units.
