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、控制元件和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。ISO 11783-10:2009描述了任务控制器应用层，它定义了任务控制器和电子控制单元之间通信所需的要求和服务。 ISO 11783-10:2009定义了与农场管理计算机通信的数据格式、控制所需的计算以及发送到控制功能的消息格式。

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. ISO 11783-10:2009 describes the task-controller applications layer, which defines the requirements and services needed for communicating between the task controller and electronic control units. The data format to communicate with the farm-management computer, the calculations required for control and the message format sent to the control function are defined in ISO 11783-10:2009.
