所以，大型PLC的工作速度總是比小的要快。控制規(guī)模還與內(nèi)存區(qū)的大小有關(guān)。規(guī)模大，用戶程序長，要求有更大的用戶存儲區(qū)。同時點數(shù)多，系統(tǒng)的存儲器輸入、輸出的信號區(qū)（輸入輸出繼電器區(qū)或稱輸入、輸出映射區(qū)）也大。這個區(qū)大，相應(yīng)地內(nèi)部器件（解釋見后）也要增多，這些都要求有更大的系統(tǒng)存儲區(qū)。控制規(guī)模還與輸入、輸出電路數(shù)有關(guān)。如控制規(guī)模為1024點，那就得有1024條I/O電路。這些電路集成于I/O模塊中，而每個模塊有多少路的I/O點總是有數(shù)的。
