摘要
随着计算机技术、通信技术和控制技术的发展,工业现场总线对通信的实时性、可靠性和高速运算性能有了更高的要求。文章介绍基于ATMEL公司AT91系列ARM7高性能微处理器,开发CANopen通用数模I/O从站节点,大大提高从站数据传输和处理能力,并成功实现了与施耐德PLC主站之间的数据传输和实时监控功能。
with the development of computer technology, communication technology and control tech-nology, industrial field-bus has a higher demand of real-time, reability and high-speed culculation for communication. This paper introduces the development of CANopen generic digital/analog I/O slave station based on ARM7 micro CPU of ATMEL company＇s AT91 seriers, it improves the capability of hadling and transmiting the data, and it also success in contacting with Snaider PLC master station.
