用VC++开发上位机与PLC通信程序实现光饰机变频控制

Frequency Control of the Polishing Machine Based on the Communication between Omron PLC and Host Computer Programmed with VC++

介绍了利用RS232串行通信实现计算机和PLC通信的方法,并给出了用VC++6.0实现Omron可编程控制器与上位机之间通信的程序设计。此方案可成功控制变频器,从而实现对光饰机旋转盘电机的速度和时间的参数化控制。

This article introduces how to realize the communication between PC and PLC with the RS232 communication port, and provides a method of programming design based on VC ＋ ＋ 6.0. The program has been successfully applied to the parameterization control of the speed and time in the polishing machine.
