摘　　要：Modbus协议在电子控制器通讯上有广泛的应用,对其必要的掌握和应用是广大相关工程技术人员必备的能力,使用VB6.0进行程序开发有简单易学,开发周期短的特点,利用其MSComm控件通过串口通讯可以轻松实现与智能仪表等电子控制器的通讯。主要介绍了温控表通过Modbus-RTU协议模式进行通讯的方法,并以一款霍尼韦尔温控表为具体控制对象,VB6.0为程序开发平台,通过实例编程,介绍了串口与MSComm控件实现可变参数通讯和对温控表编程温控的过程。The Modbus protocol has a wide range applications in the communication of electronic controllers, the mastering and application are the necessary capabilities of the relevant engineering and technical personnel. The feauture of VB6.0 is easy to learn and develop the programg, its MSComm control through the serial communication can easily achieve communication with intelligent instruments and other electronic controller. This paper mainly introduces the method of communication between the temperature control meter and the Modbus-RTU protocol mode, and takes a Honeywell temperature control meter as the con- crete control object. VB6.0 is the program development platform, through the example programming, introducing variable pa- rameter communication and temperature control process between the serial port and the MSComm Control.
