摘要
Modbus协议是应用于电子控制器的一种通用协议。该协议已经成为我国工业自动化网络协议规范的国家标准之一。介绍了一种在VB6.0编程环境下,基于Modbus RTU规约,通过RS-485串口,实现工控机与智能仪表通信的具体方法。
Modbus protocol is a kind of general protocol applied into electron controller, which has become one of the national standard in the network protocol criterion of industrial automation. A method which realized the communication between IPC and intelligent instrument based on Modbus RTU protocol with VB 6.0 and RS-485 serial port was introduced.
