2、速可靠创建与修改对象字典的对象字典生成器ODBuilder,不仅有效减少编辑对象字典的时间,而且最大限度地避免工程师手工编辑对象字典的错误出现,为CANopen设备参数设置提供有力可靠的解决方案。关键词:CANopen,对象字典,生成器,ODBuilder,EDS文件Abstract:In this paper, on the introduction of the concept and structure of the CANopen object dictionary, combined with the shortage of common
3、methods of generating object dictionary, lead to a object dictionary generator-ODBuilder, which is quickly and reliably create and modify the CANopen object dictionary. This tool not only effectively reduce the time of editing object dictionary, but significantly minimize the o
4、ccurrence of error of manually editing the object dictionary, and provide a robust and reliable solutions for the parameter Settings of CANopen equipment.Key words: CANopen,Object dictionary,generator,ODBuilder,EDS File引言CANopen协议是一种基于控制器局域网(CAN)的应用层协议,该协议具有实时高效、组网灵活和产品兼容性高等优势,
5、CANopen协议在国内越来越受到青睐,其应用领域也越来越多广泛,不仅应用于过程与生产自动化等领域,还涉及到医疗、铁路、军事、太阳能等等领域。目前CANopen协议由CiA(CAN in Automation)组织负责管理与推广。对象字典是CANopen通信接口与应用程序之间接口,是CANopen协议的重要组成部分。在CANopen网络中,每个标准的CANopen设备都有一个对象字典,用来描述CANopen设备的全部功能。一般在7CANopen配置或者开发工程中,对象字典的创建与管理是一个不可缺少的步骤,同时也是保证CANopen正常通讯的重要保障。
