PLC的发展趋势
    随着PLC应用领域日益扩大，PLC技术及其产品结构都在不断改进，功能日益强大，性价比越来越高。

    （1）、在产品规模方面，向两极发展。一方面，大力发展速度更快、性价比更高的小型和超小型PLC。以适应单机及小型自动控制的需要。另一方面，向高速度、大容量、技术完善的大型PLC方向发展。随着复杂系统控制的要求越来越高和微处理器与计算机技术的不断发展，人们对PLC的信息处理速度要求也越来越高，要求用户存储器容量也越来越大。
    （2）、向通信网络化发展
    PLC网络控制是当前控制系统和PLC技术发展的潮流。PLC与PLC之间的联网通信、PLC与上位计算机的联网通信已得到广泛应用。目前，PLC制造商都在发展自己的通信模块和通信软件以加强PLC的联网能力。各PLC制造商之间也在协商通用的通信标准，以构成更大的网络系统。PLC已成为集散控制系统（DCS）*的组成部分。

（3）、向模块化、智能化发展
    为满足工业自动化各种控制系统的需要，近年来，PLC厂家先后开发了不少新器件和模块，如智能I/O模块、温度控制模块和专门用于检测PLC外部故障的智能模块等，这些模块的开发和应用不仅增强了功能，扩展了PLC的应用范围，还提高了系统的可靠性。
    （4）、编程语言和编程工具的多样化和标准化
    多种编程语言的并存、互补与发展是PLC软件进步的一种趋势。 PLC厂家在使硬件及编程工具换代频繁、丰富多样、功能提高的同时，日益向MAP(制造自动化协议)靠拢，使PLC的基本部件，包括输入输出模块、通信协议、编程语言和编程工具等方面的技术规范化和标准化。
