控制規(guī)模與速度有關(guān)。因?yàn)橐?guī)模大了，用戶程序也長(zhǎng)，執(zhí)行指令的速度不快，勢(shì)必延長(zhǎng)PLC循環(huán)的時(shí)間，也必然會(huì)延長(zhǎng)PLC對(duì)輸入信號(hào)的響應(yīng)。為了避免這個(gè)情況，PLC的工作速度就要快。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(zhǎng)，要求有更大的用戶存儲(chǔ)區(qū)。同時(shí)點(diǎn)數(shù)多，系統(tǒng)的存儲(chǔ)器輸入、輸出的信號(hào)區(qū)（輸入輸出繼電器區(qū)或稱輸入、輸出映射區(qū)）也大
