从中可以看出，plc控制系统的输入、输出部分和电器控制系统的输入、输出部分基本相同，但控制部分是采用“可编程”的plc，而不是实际的继电器线路。因此，plc控制系统可以方便地通过改变用户程序，以实现各种控制功能，从根本上解决了电器控制系统控制电路难以改变的问题。同时，plc控制系统不仅能实现逻辑运算，还具有数值运算及过程控制等复杂的控制功能。 其中输入部分是由各种输入设备，如按钮、位置开关及传感器等组成；控制部分是按照控制要求设计的，由若干继电器及触点构成的具有一定逻辑功能的控制电路；输出部分是由各种输出设备，如接触器、电磁阀、指示灯等执行元件组成。电器控制系统是根据操作指令及被控对象发出的信号，由控制电路按规定的动作要求决定执行什么动作或动作的顺序，然后驱动输出设备去实现各种操作。由于控制电路是采用硬接线将各种继电器及触点按一定的要求连接而成，所以接线复杂且故障点多，同时不易灵活改变。 自从台plc出现以后，日本、德国、法国等也相继开始研制plc，并得到了迅速的发展。 目前，世界上有200多家plc厂商，400多品种的plc产品，按地域可分成美国、欧洲、和日本等三个流派产品，各流派plc产品都各具特色，如日本主要发展中小型plc，其小型plc性能，结构紧凑，价格便宜，在世界市场上占用重要地位。的plc生产厂家主要有美国的a-b（allen-bradly）公司、ge（generalelectric）公司，日本的三菱电机（mitsubishielectric）公司、欧姆龙（omron）公司，德国的aeg公司、西门子（siemens）公司，法国的te（telemecanique）公司等 我国的plc研制、生产和应用也发展很快，尤其在应用方面更为突出。在20世纪70年代末和80年代初，我国随国外成套设备、专用设备引进了不少国外的plc。此后，在传统设备改造和新设备设计中，plc的应用逐年增多，并取得显著的经济效益，plc在我国的应用越来越广泛，对提高我国工业自动化水平起到了巨大的作用。 目前，我国不少科研单位和工厂在研制和生产plc，如辽宁无线电二厂、无锡华光电子公司、上海香岛电机制造公司、厦门a-b公司等 plc可编程序控制器：plc英文全称programmablelogiccontroller,中文全称为可编程逻辑控制器，定义是:一种数字运算操作的电子系统，专为在工业环境应用而设计的。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算,顺序控制，定时，计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。dcs集散系统:dcs英文全称distributedcontrolsystem,中文全称为集散型控制系统。dcs可以解释为在模拟量回路控制较多的行业中广泛使用的，尽量将控制所造成的危险性分散,而将管理和显示功能集中的一种自动化高技术产品。dcs一般由五部份组成：1：控制器2：i/o板3：操作站4：通讯网络5：图形及遍程软件。在工业生产过程中，大量的开关量顺序控制，它按照逻辑条件进行顺序动作，并按照逻辑关系进行连锁保护动作的控制，及大量离散量的数据采集。传统上，这些功能是通过气动或电气控制系统来实现的。1968年美国gm（通用汽车）公司提出取代继电气控制装置的要求，第二年，美国数字公司研制出了基于集成电路和电子技术的控制装置，首次采用程序化的手段应用于电气控制，这就是代可编程序控制器，称programmablecontroller（pc）。
个人计算机（简称pc）发展起来后，为了方便，也为了反映可编程控制器的功能特点，可编程序控制器定名为programmablelogiccontroller（plc），现在，仍常常将plc简称pc。
plc的定义有许多种。国际电工委员会（iec）对plc的定义是：可编程控制器是一种数字运算操作的电子系统，专为在工业环境下应用而设计。它采用可编程序的存贮器，用来在其内部存贮执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，并通过数字的、模拟的输入和输出，控制各种类型的机械或生产过程。可编程序控制器及其有关设备，都应按易于与工业控制系统形成一个整体，易于扩充其功能的原则设计。
上世纪80年代至90年代中期，是plc发展快的时期，年增长率一直保持为30~40%。在这时期，plc在处理模拟量能力、数字运算能力、人机接口能力和网络能力得到大幅度提高，plc逐渐进入过程控制领域，在某些应用上取代了在过程控制领域处于统治地位的dcs系统。
plc具有通用性强、使用方便、适应面广、可靠性高、抗干扰能力强、编程简单等特点。plc在工业自动化控制特别是顺序控制中的地位，在可预见的将来，是无法取代的。从结构上分，plc分为固定式和组合式（模块式）两种。固定式plc包括cpu板、i/o板、显示面板、内存块、电源等，这些元素组合成一个不可拆卸的整体。模块式plc包括cpu模块、i/o模块、内存、电源模块、底板或机架，这些模块可以按照一定规则组合配置。
cpu是plc的核心，起神经中枢的作用，每套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。
cpu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，cpu单元还包括外围芯片、总线接口及有关电路。内存主要用于存储程序及数据，是plc不可缺少的组成单元。
在使用者看来，不必要详细分析cpu的内部电路，但对各部分的工作机制还是应有足够的理解。cpu的控制器控制cpu工作，由它读取指令、解释指令及执行指令。但工作节奏由震荡信号控制。运算器用于进行数字或逻辑运算，在控制器指挥下工作。寄存器参与运算，并存储运算的中间结果，它也是在控制器指挥下工作。
cpu速度和内存容量是plc的重要参数，它们决定着plc的工作速度，io数量及软件容量等，因此限制着控制规模。
plc与电气回路的接口，是通过输入输出部分（i/o）完成的。i/o模块集成了plc的i/o电路，其输入暂存器反映输入信号状态，输出点反映输出锁存器状态。输入模块将电信号变换成数字信号进入plc系统，输出模块相反。i/o分为开关量输入（di），开关量输出（do），模拟量输入（ai），模拟量输出（ao）等模块。
开关量是指只有开和关（或1和0）两种状态的信号，模拟量是指连续变化的量。常用的i/o分类如下：开关量：按电压水平分，有220vac、110vac、24vdc，按隔离方式分，有继电器隔离和晶体管隔离。模拟量：按信号类型分，有电流型（4-20ma,0-20ma）、电压型（0-10v,0-5v,-10-10v）等，按精度分，有12bit,14bit,16bit等除了上述通用io外，还有特殊io模块，如热电阻、热电偶、脉冲等模块。
按i/o点数确定模块规格及数量，i/o模块可多可少，但其大数受cpu所能管理的基本配置的能力，即受大的底板或机架槽数限制。 plc电源用于为plc各模块的集成电路提供工作电源。同时，有的还为输入电路提供24v的工作电源。电源输入类型有：交流电源（220vac或110vac），直流电源（常用的为24vdc）。 大多数模块式plc使用底板或机架，其作用是：电气上，实现各模块间的联系，使cpu能访问底板上的所有模块，机械上，实现各模块间的连接，使各模块构成一个整体。
编程设备：编程器是plc开发应用、监测运行、检查维护不可缺少的器件，用于编程、对系统作一些设定、监控plc及plc所控制的系统的工作状况，但它不直接参与现场控制运行。小编程器plc一般有手持型编程器，目前一般由计算机（运行编程软件）充当编程器。人机界面：简单的人机界面是指示灯和按钮，目前液晶屏（或触摸屏）式的一体式操作员终端应用越来越广泛，由计算机（运行组态软件）充当人机界面非常普及。输入输出设备：用于性地存储用户数据，如eprom、eeprom写入器、条码阅读器，输入模拟量的电位器，打印机等。
依靠的工业网络技术可以迅速有效地收集、传送生产和管理数据。因此，网络在自动化系统集成工程中的重要性越来越显著，甚至有人提出'网络就是控制器'的观点说法plc具有通信联网的功能，它使plc与plc之间、plc与上位计算机以及其他智能设备之间能够交换信息，形成一个统一的整体，实现分散集中控制。多数plc具有rs-232接口，还有一些内置有支持各自通信协议的接口。
plc的通信，还未实现互操作性，iec规定了多种现场总线标准，plc各厂家均有采用。对于一个自动化工程(特别是中大规模控制系统)来讲，选择网络非常重要的。首先，网络必须是开放的，以方便不同设备的集成及未来系统规模的扩展；其次，针对不同网络层次的传输性能要求，选择网络的形式，这必须在较深入地了解该网络标准的协议、机制的前提下进行；再次综合考虑系统成本、设备兼容性、现场环境适用性等具体问题，确定不同层次所使用的网络标准。
配电箱、柜的所有技术指标必须符合规范及设计要求。投标人应明确生产的产品执行的标准（国家标准gb7251、行业标准、企业标准），并根据所依据的标准提供相应的国标、行标或企标（企业标准应高于国标或行标）。
所有的电气元件及技术参数必须符合设计要求，如需更改必须按正规工程资料（洽商）表格的要求填写并经设计院、建设单位、监理、施工单位及厂方代表共同签字认可。否则由此产生的损失由供货单位负责。
根据本工程图纸选有代表性的暗装箱、明装箱、配电柜生产样品，完后通知建设单位、监理、施工单位有关人员验收通过后，方可全面生产。
