1、 前言

可编程逻辑控制器是种专门为在工业环境下应用而设计的数字运算操作电子系统。它采用一种可编程的存储器,在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令,通过数字式或模拟式的输入输出来控制各种类型的机械设备或生产过程。

2、 方案概述

Ameya360 可编程逻辑控制器解决方案的输入 / 输出部分:输入部分或输入模块由诸如传感器,开关和许多其他真实世界输入源的设备组成。来自输入源的输入通过输入连接器导轨连接到 PLC。输出部分或输出模块可以是马达或螺线管或灯或加热器,其功能通过改变输入信号来控制。CPU 或中央处理单元:这是 PLC 的大脑。它可以是六角形或八角形的微处理器。它执行与输入信号相关的所有处理,以基于控制程序来控制输出信号。编程器:编写程序或控制逻辑的平台。它可以是手持设备,笔记本电脑或电脑本身。电源:通常工作在 24 V 左右的电源上,用于为输入和输出设备供电。存储器:存储器分为两部分 - 数据存储器和程序存储器。程序信息或控制逻辑被存储在用户存储器或 CPU 取出程序指令的程序存储器中。输入和输出信号以及定时器和计数器信号分别存储在输入和输出外部图像存储器中。
