描述
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。该空间的主要部分用于存放工作数据称为数据存储器,另外有一部分作寄存器使用称为数据对象。
