提高外部设备的响应速度。在PLC内部实现高速化的同时，还要提高外部设备的响应速度，才能整体提高整个系统的性能，为此，在缩短I/O模块的输入输出响应时间，提高模拟量输入输出模块的模-数和数-模转换时间，下了不少工夫，以求得系统整体的控制速度达到毫秒级以下。例如，在晶体管输出模块的输出电路中选用高性能的晶体管，使响应时间加快50%；在直流输入模块中，其输入的时间常数回路采用专用ASIC芯片，可通过编程软件选择输入模块的响应时间为1/5/10/20/70毫秒；为提高模拟量模块的转换时间，采用A/D或D/A的专用芯片，是转换速度为原先的1/2—1/6。另外也通过开发专用的处理器和通信专用ASIC，缩短通信网络模块之间的通信链接的循环时间。
信息技术渗入PLC。信息技术渗入PLC是为了适应工厂控制系统和企业信息管理系统日益有机结合的发展趋势；适应在控制层面让不同品牌的PLC之间，让PLC与DCS、SCADA等系统之间，能有效而足够快地交换数据的市场要求。它主要表现在：
1）让以Windows操作系统的PC机嵌入PLC系统[见上述第（1）节]。
