CAN Primer: Creating your own Network
There are many “application” layers available for CAN such as ISO 15765 (cars), J1939 (trucks), DeviceNET and CANopen (these are for factory automation). CAN has become the standard for vehicle networks, but it has been adopted in most other fields. As you find out in these pages, there are no attributes in the Bosch CAN specification that are automotive related. It is completely generic. You can easily implement your own protocol on top of CAN to fit your needs. This primer will guide you in making the right choices when implementing a system.
