This part of ISO 11783 specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, semi-mounted, towed or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensor, actuators, control elements, and information-storage and -display units, whether mounted on, or part of, the tractor or implement. This part of ISO 11783 describes the tractor ECU, the electronic control unit that provides the gateway between the network’s tractor and implement buses, as well as performing other functions.
NOTE The tractor ECU is also the node that represents the tractor, or analogous functions within self-propelled machines, for functions such as the virtual terminal on the implement bus.
