可编顺序控制器是近年来出现的一种介于计算机和简易顺序控制器之间的自动控制装置,由于它兼有上述两种装置之间的一系列优点,因此它可以广泛的用于冶金,机械制造,石油化工,电力,纺织,食品加工等工业中的程序控制。本文除了介绍可编顺序控制器的基本原理,特点外,还介绍了本装置的技术指标,指令系统,程序编制,几个部件以及在研制过程中,要注意的一些问题。
The programmable sequence controller is an automatic control device that has appeared in recent years between a computer and a simple sequential controller. It can be widely used in metallurgy because of its advantages over a series of advantages between the two devices. , Machinery manufacturing, petrochemical, power, textile, food processing and other industries in the process control. In addition to introducing the basic principles and characteristics of the programmable sequence controller, this paper also introduces the technical indicators, instruction system, programming, several components and some issues to be noticed in the development of this device.
