基于VB和RS-485总线技术的变频器控制系统的设计与实现

On the Design and Realization of Transducer Control System Based on Bus Technology of VB and RS-485

本文介绍MSComm控件实现对变频器的控制,并以RS-485总线技术系列变频器为例,描述了系统的收发数据桢的程序设计,并给出了利用串口进行收发数据桢的程序设计的代码。

This article introduces that MSComm controls realize the control of the frequency changer, and takes the example of the frequency changer of the series of the RS - 485 bussing technique . It describes the programming that can receive and dispatch data hardwood in system, and give the programming code that can receive and dispatch data hardwood by using the serial port.
