　 PLC的CPU模塊通過系統(tǒng)總線（一般做在基板的印刷電路上）與裝插在基板上的各種I/O模塊、特殊功能模塊、通信模塊等交換數(shù)據(jù)，裝插的模塊越多，CPU模塊與那些模塊之間的數(shù)據(jù)交換的時間就會增加。這種數(shù)據(jù)交換的時間的增加，在一定程度上會使PLC的掃描時間加長。因此，有必要采取以下措施使系統(tǒng)總線傳輸速度高速化：增加系統(tǒng)總線的帶寬使一次傳輸?shù)臄?shù)據(jù)量增多，例如三菱電機的小Q系列PLC，增加了系統(tǒng)總線的帶寬，使所傳輸?shù)臄?shù)據(jù)量是以前的2倍；在系統(tǒng)總線存取的方式上，采用連續(xù)成組傳送技術(shù)實現(xiàn)連續(xù)數(shù)據(jù)的高速批量傳送，大大縮短了存取每個字所需的時間；通過向與系統(tǒng)總線相連接的模塊實現(xiàn)全局傳送，即針對多個模塊同時傳送同一數(shù)據(jù)，有效地用活了系統(tǒng)總線。
