J1939 defines a transport protocol TP. It uses sequences of 8 byte messages to transfer longer data. It is defined in the Standard. In CANopen such a transport protocol is defined as one of the SDO (service data object) protocols. Basic introduction at https://www.kvaser.com/about-can/higher-layer-protocols/j1939-introduction/ If you are interested in implementing J1939, search for protocol stack providers. You can ask me for references. Heinz -- Archives and useful links: http://groups.yahoo.com/group/CANbus Subscribe and unsubscribe at www.vector.com/canlist/ Report any problems to <[email protected]>
