ISO/TC 23/SC 19/WG 1 - Applications and data interfaces

This document describes the implement messages application layer of the network, specifying the message set and defining the messages used for communication with and between tractors and connected implements.

This document specifies an extensible communication system concept and defines rules for adding new functionalities to cover specific use cases.

The message set specified in this document is designed to support the needs of tractors and implements in using the services of a file server (FS). An FS is a distinct control function (CF) on the mobile implement control system that enables all CFs to store or retrieve data from a file-based storage device.

This document provides design requirements and guidance for the manufacturers of electrical and electronic equipment for use in all kinds of mobile (including hand-held) agricultural machinery, forestry machinery, landscaping and gardening machinery [referred to hereafter as machine(s)]. The term machinery covers tractors and implements. This document gives tests for specific environmental conditions and defines severity levels for tests which relate to the environmental extremes that can be experienced in practical operation of the equipment. This document is intended to be used in determining the suitability of the equipment of these machines, for use in a specified range of environmental conditions. NOTE The severity levels given are general guidelines and not guaranteed worst-case exposure levels.

This document describes the management of source addresses (SAs) for control functions (CFs) of electronic control units (ECUs), the association of addresses with the functional identification of a device and the detection and reporting of network-related errors. It also specifies procedures for initialization of network-connected ECUs.

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 sensors, actuators, control elements, and information-storage and -display units, whether mounted on, or part of, the tractor or implement. ISO 11783 also provides an open interconnect system for on-board electronic systems used by agriculture and forestry equipment. It is intended to enable electronic control units (ECUs) to communicate with each other, providing a standardized system. This document defines and describes the network's 250 kbit/s, twisted, non-shielded, quad-cable physical layer and an alternative cable and architecture named twisted pair physical layer (TPPL) based on a 250 kbit/s, un-shielded, twisted pair cable network layer which is fully backward compatible to twisted quad based machines and devices. NOTE Where not differently specified, requirements are valid for both twisted quad and TPPL.
