摘要
本文简要介绍了Modbus通信协议的RTU模式特点,阐述了该协议在VB6.0编程环境下通过MSComm控件实现工控机与火灾报警终端通信的具体方法。该方法简单实用,对类似系统的设计开发有一定的借鉴作用。
The features of the Modbus communication protocol in RTU mode are introduced briefly.The method for realizing the communication between IPC and Terminal of fire alarm based on Modbus protocol is also explained.The serial communication is programmed with MSComm control under VB.It is easy and practical,and can provide certain references for the design and development of similar systems.
