ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors, mounted, semi-mounted, towed or self propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control elements, information storage and display units whether mounted, or part of the tractor or any implement.

This part of ISO 11783 specifies a sequence control system, such as a headland management system, which includes tractor and implement functions in one system. The system allows recording of multiple sequences of operator-activated functions from a tractor or any other control function on the ISO 11783 network, and replaying them on operator command.
