摘要
介绍了Modbus RTU通讯协议的特点,阐述了该协议在VB6.0编程环境下通过RS-485串口实现工控机与智能仪表通信的具体方法.该方法简单实用,对其他同类型智能仪器及系统的设计开发有一定的借鉴作用.
The features of the Modbus communication protocol are introduced. The concrete method for realizing the communication between IPC and intelligent instrument based on Modbus RTU protocol under the environment of VB6.0 program and RS-485 serial port is also explained. It is simple, reliable and effective, and can provide certain references for the design and development of similar intelligent instruments and systems.
