ISO 11783作为一个整体，规定了一个串行数据网络，用于林业或农业拖拉机以及安装、半安装、牵引或自推进机具的控制和通信。其目的是标准化传感器、执行器、控制元件、信息存储和显示单元之间的数据传输方法和格式，无论是安装在拖拉机或机具上，还是拖拉机或机具的一部分。本文档描述了网络的诊断系统。 注:本文件维护机构的名称和联系方式可在http://www.iso.org/mara.

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 sensors, actuators, control elements and information storage, and display units, whether mounted on, or part of, the tractor or implement. This document describes the network's diagnostic system. NOTE The name and contact information of the Maintenance Agency for this document can be found at http://www.iso.org/mara.
