摘要
为了具备与Internet的互联能力,遇到的首先就是协议转换的问题,本课题介绍如何将MO DBUS协议转换为WEB服务器的HTTP协议,设计一个网关以及基于Cortex-M3微处理器结合R S232构建了Modbus协议转换模块。模块可通过R S232通讯方式与各种支持Modbus协议的设备进行通讯,可以将Modbus设备连入Internet,通过该模块的协议转换功能,能够通过Internet对Modbus设备实施网络化远程控制。
InordertohavetheInternetconnectivity,thefirstistheprotocolconversionproblems,thistopicintroduceshowtoconvertMODBUSpro-tocol to the WEB server's HTTP protocol, and design a gateway based on microprocessor architecture Cortex-M3 combined with RS232 ,and the MODBUS protocol conversion module is constructed. It can communicate with al kinds of equipment supportting the Modbus protocol through RS232, Modbus devices can be connected to the Internet, through the module of protocol conversion function, it can implement networked remote controltotheModbusdevices throughtheInternet.
