What is a PLC?
What are PLCs and how
do they work?
PLCs are often defined as miniature industrial
computers that contain hardware and
software used to perform control functions.
A PLC consists of two basic sections: the
central processing unit (CPU) and the
input/output interface system. The CPU,
which controls all PLC activity, can further
be broken down into the processor and
memory system. The input/output system
is physically connected to field devices
(e.g., switches, sensors, etc.) and provides
the interface between the CPU and the
information providers (inputs) and controllable
devices (outputs).
To operate, the CPU “reads” input data
from connected field devices through the
use of its input interfaces, and then
“executes” or performs the control
program that has been stored in its
memory system. Programs are typically
created

什么是控制器? 什么是PLC和他们如何工作? PLC的定义往往带有微型计算机硬件和软件工业来履行控制职能. 一个控制器分为两个基本部分:中央处理器(CPU的)和输入/输出介面系统. CPU的,它掌握所有的PLC活性,可进一步细分为处理器和存储器系统. 输入/输出系统是肢体相连场装置(例如,开关、传感器、 等),并提供CPU的接口和信息提供商(投入产出)和可控装置(). 操作,CPU的"写"输入数据从连接器领域的投入,通过使用界面, 然后"处决"或演出的控制程序,它已储存记忆系统. 节目通常开设阶梯逻辑语言相似中继型接线示意图, 而进入CPU的记忆之前运行. 最后,根据规划,临"写"或更新设备输出经输出介面. 这个过程也称为扫描,通常在同一顺序依然没有中断, 只有变化改变了控制计划. 离散应用通常用来控制PLC的机器或进程正在有序性 用"离散"的投入和产出,确定国家. 例如,如果发现存在一个极限开关物体 它提供了一个"关于"信号的控制器; 如果发现任何物体,它提供了一个"客"的信号. 一般机器或器件进行的行动或基于时间的事件预设秩序. 预计发运顺序通常只有在发生不正常状况.
