PLC分为箱体式和模块式两种。但它们的组成是相同的,对箱体式PLC,有一块CPU板、I/O板、显示面板、内存块、电源等,当然按CPU性能分成若干型号,并按I/O点数又有若干规格。对模块式PLC,有CPU模块、I/O模块、内存、电源模块、底板或机架。无任哪种结构类型的PLC,都属于总线式开放型结构,其I/O能力可按用户需要进行扩展与组合。PLC的基本结构组成如下:
CPU的构成

PLC中的CPU是PLC的核心,起神经中枢的作用,每台PLC至少有一个CPU,它按PLC的系统程序赋予的功能接收并存贮用户程序和数据,用扫描的方式采集由现场输入装置送来的状态或数据,并存入规定的寄存器中,同时,诊断电源和PLC内部电路的工作状态和编程过程中的语法错误等。进入运行后,从用户程序存贮器中逐条读取指令,经分析后再按指令规定的任务产生相应的控制信号,去指挥有关的控制电路,与通用计算机一样,主要由运算器、控制器、寄存器及实现它们之间联系的数据、控制及状态总线构成,还有外围芯片、总线接口及有关电路。它确定了进行控制的规模、工作速度、内存容量等。内存主要用于存储程序及数据,是PLC不可缺少的组成单元。
优势品牌:
PLC程序既有生产厂家的系统程序,又有用户自己开发的应用程序,系统程序提供运行平台,同时,还为PLC程序可靠运行及信息与信息转换进行必要的公共处理。用户程序由用户按控制要求设计。
般讲,
诚信=财富,小成凭智 大成凭德-“做企业,做产品,首先要从做人开始,做一个诚信的人,这样才能做一个诚信的企业
诚信是企业立业之本,发展之道,是一笔巨大的无形资产。对一个品牌、一家企业来讲,诚信是灵魂、
