　plc与PLD关于大多数操控行业的朋友们与单片机爱好者，都不是生疏的名词。可是您了解它们的“一字之差”吗？假如您对此感兴趣，就请看看小编今日介绍的内容。

　　1.可编程操控器(PLC)是计算机家族中的一员，是为工业操控应用而规划制作的。前期的可编程操控器称作可编程逻辑操控器，简称PLC，它首要用来替代继电器实现逻辑操控。跟着技能的开展，这种设备的功用已经大大超越了逻辑操控的规模，因而，今日这种设备称作可编程操控器，简称PC。但是为了避免与个人计算机的简称混杂，所以将可编程操控器简称PLC(ProgRammable Logic Controller)。

　　PLC的首要特点

　　高可靠性、丰富的I/O接口模块、选用模块化结构、编程简略易学、安装简略，修理便利

　　PLC的功用

　　逻辑操控、守时操控、计数操控、步进(次序)操控

　　PID操控

　　数据操控：PLC具有数据处理才能。

　　通讯和联网

　　其它：PLC还有许多特别功用模块，适用于各种特别操控的要求，如：定位操控模块，CRT模块。

　　2.PLD是可编程逻辑器材(ProgramableLogicDevice)的简称，fpga是现场可编程门阵列(FieldProgramableGateArray)的简称，两者的功用根本相同，只是实现原理略有不同，所以咱们有时能够疏忽这两者的差异，统称为可编程逻辑器材或PLD/FPGA。

　　PLD是电子规划领域中最具活力和开展前途的一项技能，它的影响一点点不亚于70年代单片机的发明和运用。PLD能做什么呢？能够毫不夸张的讲，PLD能完结任何数字器材的功用，上至高性能cpu,下至简略的74电路，都能够用PLD来实现。

　　PLD好像一张白纸或是一堆积木，工程师能够经过传统的原理图输入法，或是硬件描绘语言自由的规划一个数字系统。经过软件仿真，咱们能够事先验证规划的正确性。在pcb完结以后，还能够利用PLD的在线修正才能，随时修正规划而不必改动硬件电路。运用PLD来开发数字电路，能够大大缩短规划时刻，削减PCB面积，进步系统的可靠性。

　　典型的PLD由一个“与”门和一个“或”门阵列组成，而任意一个组合逻辑都能够用“与一或”表达式来描绘，所以，PLD能以乘积和的方式完结大量的组合逻辑功用.这一阶段的产品首要有PAL(可编程阵列逻辑)和GAL(通用阵列逻辑)。

　　关于可编程逻辑器材，规划人员可利用价格低廉的软件工具快速开发、仿真和测试其规划。然后，可快速将规划编程到器材中，并当即在实际运行的电路中对规划进行测试。原型中运用的PLD器材与正式生产终究设备(如网络路由器、DSL调制解调器、DVD播放器、或轿车导航系统)时所运用的PLD完全相同。这样就没有了NRE成本，终究的规划也比选用定制固定逻辑器材时完结得更快。

　　选用PLD的另一个要害长处是在规划阶段中客户可根据需求修正电路，直到对规划作业感到满足为止。这是因为PLD基于可重写的存储器技能--要改动规划，只需求简略地对器材进行从头编程。一旦规划完结，客户可当即投入生产，只需求利用终究软件规划文件简略地编程所需求数量的PLD就能够了。
