与外部设备的数据交换速度高速化。PLC的CPU模块通过系统总线（一般做在基板的印刷电路上）与装插在基板上的各种I/O模块、特殊功能模块、通信模块等交换数据，装插的模块越多，CPU模块与那些模块之间的数据交换的时间就会增加。这种数据交换的时间的增加，在一定程度上会使PLC的扫描时间加长。因此，有必要采取以下措施使系统总线传输速度高速化：增加系统总线的带宽使一次传输的数据量增多，例如三菱电机的小Q系列PLC，增加了系统总线的带宽，使所传输的数据量是以前的2倍；在系统总线存取的方式上，采用连续成组传送技术实现连续数据的高速批量传送，大大缩短了存取每个字所需的时间；通过向与系统总线相连接的模块实现全局传送，即针对多个模块同时传送同一数据，有效地用活了系统总线。
编程设备服务处理的高速化。当扫描时间为数十毫秒时，几毫秒的编程工具和监控设备的服务处理时间不会带来什么问题。但是在执行1毫秒以下的控制任务时，就有必要大大缩短这个时间。所采用的方法是以多CPU芯片并行处理的方式，由专门处理编程及监控服务的微处理器芯片执行这类处理，以减轻对执行控制程序的CPU芯片的影响，让它只管执行顺控和逻辑运算。此外，为了提高服务处理的效率，缩短在现场读写程序的时间，以缩短操作时间，采用了高速的串行通信（最大的波特率为115.2Kbps）以及将UCB口（最大波特率达12Mbps）引入PLC的CPU模块，从而实现与编程工具及监控设备之间通信的高速化，并允许同时使用这两个通信端口，由多人同时进行编程和调试。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。
