   1．向高速度、大容量方向发展

 为了提高PLC的处理能力，要求PLC具有更好的响应速度和更大的存储容量。目前，有的PLC的扫描速度可达0.1ms/k步左右。PLC的扫描速度已成为很重要的一个性能指标。

 在存储容量方面，有的PLC最高可达几十兆字节。为了扩大存储容量，有的公司已使用了磁泡存储器或硬盘。

    2．向超大型、超小型两个方向发展

 当前中小型PLC比较多，为了适应市场的多种需要，今后PLC要向多品种方向发展，特别是向超大型和超小型两个方向发展。现已有I/O点数达14336点的超大型PLC，其使用32位微处理器，多CPU并行工作和大容量存储器，功能强。

 小型PLC由整体结构向小型模块化结构发展，使配置更加灵活，为了市场需要已开发了各种简易、经济的超小型微型PLC，最小配置的I/O点数为8～16点，以适应单机及小型自动控制的需要，如三菱公司α系列PLC。

    3．PLC大力开发智能模块，加强联网通信能力

 为满足各种自动化控制系统的要求，近年来不断开发出许多功能模块，如高速计数模块、温度控制模块、远程I/O模块、通信和人机接口模块等。这些带CPU和存储器的智能I/O模块，既扩展了PLC功能，又使用灵活方便，扩大了PLC应用范围。

加强PLC联网通信的能力，是PLC技术进步的潮流。PLC的联网通信有两类：一类是PLC之间联网通信，各PLC生产厂家都有自己的专有联网手段；另一类是PLC与计算机之间的联网通信，一般PLC都有专用通信模块与计算机通信。为了加强联网通信能力，PLC生产厂家之间也在协商制订通用的通信标准，以构成更大的网络系统，PLC已成为集散控制系统（DCS）不可缺少的重要组成部分。

     4．增强外部故障的检测与处理能力

     根据统计资料表明：在PLC控制系统的故障中，CPU占5%，I/O接口占15%，输入设备占45%，输出设备占30%，线路占5%。前二项共20%故障属于PLC的内部故障，它可通过PLC本身的软、硬件实现检测、处理；而其余80%的故障属于PLC的外部故障。因此，PLC生产厂家都致力于研制、发展用于检测外部故障的专用智能模块，进一步提高系统的可靠性。

    5．编程语言多样化

  在PLC系统结构不断发展的同时，PLC的编程语言也越来越丰富，功能也不断提高。除了大多数PLC使用的梯形图语言外，为了适应各种控制要求，出现了面向顺序控制的步进编程语言、面向过程控制的流程图语言、与计算机兼容的高级语言（BASIC、C语言等）等。多种编程语言的并存、互补与发展是PLC进步的一种趋势。
