MODBUS通信协议在现场水泥成分X荧光分析仪中的应用

The application of MODBUS protocol in XFR instrument used to analyze the cement composition

首先对MODBUS通信协议进行了简单介绍,然后讨论了采用MODBUS通信协议的水泥成分X荧光分析仪是如何实现与水泥生产自动化总控制系统之间的数据传输的,由此达到控制水泥配料系统自动配料的目的。并给出了VisualC++下实现通讯的方法。

This paper briefly introduced the MODBUS protocol at the beginning. Then the data communication between XFR instrument and the main controlling system of cement production is discussed. The diagram of data communication and part of member functions of serial port class are provided, under Visual C++ programming language.
