用欧姆龙PLC与上位机通信实现振动磨的变频控制

Realization of Variable Frequency Control to the Vibration Mill with the Communication between OMRON PLC and the Upper-Position Processor

给出了用VC++6.0实现OMRON可编程控制器与上位机之间的通信程序设计方法,并提供了利用RS232串行通讯端口实现计算机与可编程控制器通讯的方法。此方案成功应用在振动磨的变频控制中。

The paper offers the approach to design the program for realizing the communication between OMRON programmable controller and the upper-position processor by VC++6.0, and provides the approach to realize the communication between the computer and the PLC with RS232 tandem communication port. The scheme has been success- fully applied to the variable frequency control to the vibration mill.
