基于LabVIEW的MODBUS测控系统的实现

The Realization of the MODBUS Measurement and Control System Based on LabVIEW

该文简要介绍了MODBUS通讯协议,阐述了MODBUS测控系统的结构。其次,在LabVIEW环境下,利用Windows API编程实现了MODBUS协议通讯模块,并对其有效性进行了验证。最后利用LabVIEW的Web发布功能对测控程序进行了发布。

This paper briefly introduces the MODBUS communication protocol,describes the structure of MODBUS control system.Secondly,in the LabVIEW environment,used Windows API programming to achieve the MODBUS protocol communication module,and its validity is proved.Finally using LabVIEW Web publishing function to release control program.
