PLC內(nèi)存有用戶及系統(tǒng)兩大部分。用戶內(nèi)存主要用以存儲(chǔ)用戶程序，個(gè)別的還將其中的一部分劃為系統(tǒng)所用。系統(tǒng)內(nèi)存是與CPU配置在一起的。CPU既要具備訪問(wèn)這些內(nèi)存的能力，還應(yīng)提供相應(yīng)的存儲(chǔ)介質(zhì)。
用戶內(nèi)存大小與可存儲(chǔ)的用戶程序量有關(guān)。內(nèi)存大，可存儲(chǔ)的程序量大，也就可進(jìn)行更為復(fù)雜的控制。從發(fā)展趨勢(shì)看，內(nèi)存容量總是在不斷增大著。大型PLC的內(nèi)存容量可達(dá)幾十k，以至于一百多k。系統(tǒng)內(nèi)存對(duì)于用戶，主要體現(xiàn)在PLC能提供多少內(nèi)部器件。不同的內(nèi)部器件占據(jù)系統(tǒng)內(nèi)存的不同區(qū)域。在物理上并無(wú)這些器件，僅僅為RAM。但通過(guò)運(yùn)行程序進(jìn)行使用時(shí)，給使用者提供的卻實(shí)實(shí)在在有這些器件。 現(xiàn)貨，現(xiàn)貨，降降降，火火火，火火火……
