PLC可编程控制器的特点
    1）、可靠性高，抗*力强。工业生产一般对控制设备的可靠性要求很高，并且要有很强的抗*力。PLC能在恶劣的环境中可靠的工作，平均*时间达到数万小时以上，已被*为zui可靠的工业控制设备之一。
    PLC本身具有较强的自诊断功能，保证硬件核心设备（CPU、存储器、I/O总线等）在正常情况下执行用户程序，一旦出现故障则立即给出出错信号，停止用户程序的执行，切断所有输出信号，等待修复。PLC的主要模块均采用大规模和超大规模集成电路，I/O系统设计有完善的通道保护与信号调理电路。在结构上对耐热、防潮、防尘、抗震等都有精确的考虑，在硬件上采用隔离，屏蔽、滤波、接地等抗干扰措施，在软件上采用数字滤波等措施。与继电器系统和通用计算机相比，PLC更能适应工业现场环境要求。
    2） 硬件配套齐全，使用方便，适应性强
    PLC是通过执行程序实现控制的。当控制要求发生改变时，只要修改程序即可，zui大限度地缩短了工艺更新所需要的时间。PLC的产品已标准化、系列化、模块化，而且PLC及配套产品的模块品种多，用户可以灵活方便地进行系统配置组合成各种不同规模、不同功能的控制系统。在PLC控制系统中，只需在PLC的端子上接入相应的输入/输出信号线即可，不需要进行大量且复杂的硬接线，并且PLC有较强的带负载能力，可以直接驱动一般的电磁阀和交流接触器。
    3）、编程直观、易学易会
    PLC提供了多种编程语言，其中梯形图使用zui普遍。PLC是面向用户的设备，PLC的设计者充分考虑到现场工程技术人员的技能和习惯，因此PLC程序的编制采用梯形图的简单指令形式。梯形图与继电原理图相似，这种编程语言形象直观，易学易懂，不需要专门的计算机知识和语言，现场工程技术人员可在短时间内学会使用。用户在购买PLC后，只需按说明书的提示，做少量的接线和进行简易的用户程序编制工作，就可灵活方便地将PLC应用于生产实践。

  4）、系统的设计、安装、调试工作量小，维护方便
    PLC用软件取代了继电器控制系统中大量的中间继电器、时间继电器、计数器等器件，使控制柜的设计、安装、接线工作量大为减少。同时PLC的用户程序大部分可以在实验室进行模拟调试，模拟调试好后再将PLC控制系统安装到生产现场，进行联机调试，既安全，又快捷方便。
    PLC的故障率很低，并且有完善的自诊断和显示功能。当发生故障时，可以根据PLC的状态指示灯显示或编程器提供的信息迅速查找到故障原因，排除故障。
    5）、体积小，能耗低
    由于PLC采用了半导体集成电路，其体积小，重量轻，结构紧凑、功耗低、便于安装，是机电一体化的理想控制器。对于复杂的控制系统，采用PLC后，一般可将开关柜的体积缩小到原来的1/10~1/2。
