ISO 11783 as a whole 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 (TECU), the control function (CF) that provides the gateway between the network’s tractor and implement buses, as well as performing other functions.

New requirements in this second edition are specified as version 2 TECUs and Working Sets.

NOTE The Tractor ECU is also the control function (CF) that represents the tractor, or analogous functions within self-propelled machines, for functions such as the virtual terminal on the implement bus.

This document applies to wheeled and/or track-laying self-propelled agricultural and forestry vehicles when used on public roads. It specifies the definitions, construction and performance requirements and the means for verification of braking systems on vehicles with a maximum design speed not exceeding 60 km/h.

Following items are excluded from the scope of this document:

— coupling force control;

— endurance braking systems;

— Anti-Lock Braking Systems and EBS;

— vacuum braking systems;

— safety related parts of complex electronic control systems;

— trailer braking control systems.
