摘　　要：在对CC-Link总线协议进行仔细研究的基础上,以MFP3高性能通信芯片为核心,以AT89S52单片机为控制器,结合RS-485底层通信,设计了一种能与以PLC为主站的CC-Link网络通信的设备站。这种设备站具备了CC-Link远程设备站站号设置、波特率调整等功能,既易于二次开发拓展,又易于连接设备。使用此设备站,能将原有设备经简单调整后接入CC-Link网络,构成集中控制系统,可节约工厂升级系统的资金。所构建的低成本硬件平台,是一种高效节能的控制系统,对推广高效节能系统在中国的发展,推动国家现代化经济建设具有一定的意义。On the basis of research of the CC-Link fieldbus agreement,using the MFP3 high performance communication as microchip,the AT89S52 MCU as the controller,and combining 485 bottom communication mode,a CC-Link fieldbus remote device station which can communicate with the PLC as the master station is designed.This interface has the function of setting the number of the remote device station,adjusting the communication baud rate and so on.This remote device station is very easy to exploit and connect with the other device.This kind of device station can connect the existing device to the CC-Link fieldbus only by a little adjustment to constitute a centralized control system so as to save the money to upgrade the production system.The low-cost hardware platform mentioned is a kind of energy efficient control system,it is very helpful to the promotion of energy-saving and efficient system's development in China,and has some significance to promote national economic modernization.
