Copperhill Media offers a variety of literature on the Controller Area Network (CAN), CANopen and SAE J1939 Protocol Standards. All books are available as paperback, but can also be downloaded in eBook (PDF) form.
A feature of the CAN protocol is that the bit rate, bit sample point and number of samples in a bit period are user programmable. This gives the user the freedom to optimize the performance of the network for his given application.
SAE J1939 has become the accepted industry standard and the vehicle network technology of choice for off-highway machines in applications such as construction, material handling, and forestry machines. J1939 is a higher-layer protocol based on Controller Area Network (CAN). It provides serial data communications between microprocessor systems (also called Electronic Control Units – ECU) in any kind of heavy duty vehicles. The messages exchanged between these units can be data such as vehicle road speed, torque control message from the transmission to the engine, oil temperature, and many more.
