1. 产品规模向大、小两个方向发展
大： I/O点数达14336点、32位为微处理器、多CPU并行工作、大容量存储器、扫描
速度高速化。
小： 由整体结构向小型模块化结构发展，增加了配置的灵活性，降低了成本。
2. PLC在闭环过程控制中应用日益广泛
3. 不断加强通讯功能
4. 新器件和模块不断推出
*的PLC除了主要采用CPU以提高处理速度外，还有带处理器的EPROM或RAM的智能I/O模块、高速计数模块、远程I/O模块等化模块。
5. 编程工具丰富多样，功能不断提高，编程语言趋向标准化
有各种简单或复杂的编程器及编程软件，采用梯形图、功能图、语句表等编程语言，亦有*的PLC指令系统。
6. 发展容错技术
采用热备用或并行工作、多数表决的工作方式。
7.追求软硬件的标准化。
