CAN, J1939 & CANOpen

CAN bus (Controller Area Network) is a vehicle bus communications interface originally developed by Bosch. It is one for the protocols used in the OBD-II vehicle diagnostics standard and is widely used across many industries, in addition to automotive. It has two parts: the standard format with an 11-bit identifier, and the extended format with a 29-bit identifier. The most recent specification is CAN 2.0, which was published in 1991.

SAE J1939 is a commonly used protocol for communication and diagnostics between components in commercial vehicles. It originated in the car and heavy-duty truck industry in the United States, and is now widely used in other parts of the world.

Speedgoat provide comprehensive support for CAN, SAE J1939 and CANOpen networks with the IO601 CAN I/O module, which comes with Simulink driver blocks.
