摘要
可编程控制器作为一种高性能的控制装置,已被广泛应用于各种生产过程的自动控制。在分布式控制系统中,将它与计算机(PC)结合起来使用,互补功能上的不足,具有更强的数据采集、数据处理功能,能实现较大规模的复杂控制。介绍日本OMRON公司生产的CQM1型PLC与上位计算机PC实现串行通信的方法。
As a high - quality control equipment, PLC is widely applied to all kinds of automatic control of production process. It is combined with the computers (PC) in the distributed control system to mend shortcoming in the function mutually, and possesses the stronger data acquisition and the data processing function, and can realize more full - scale complicated control. This article introduces means of serial communication between CQM1 - type PLC produced by Japan OMRON company and PC.
