J1939-based networks are used in most of the in-vehicle networks in trucks and buses and in some off-road vehicles. In addition, some off-highway vehicles such as agriculture and forestry machines and military vehicles are equipped with J1939-based networks. Because in Europe, many of the super-construction manufacturers like to use off-the-shelf, price-competitive devices originally developed for other applications fields, they like to buy CANopen-based modules. CANopen is a standardized CAN-based application layer and profile specification. In order to standardize the gateway functionality, a CANopen device profile for J1939 truck gateway is introduced.
