描述

与外部设备的数据交换速度高速化。PLC的模块通过系统总线（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，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。
