在低檔PLC中，用Z80A做CPU較為廣泛，Z80A用于PLC有如下長處： Z80（或Z80A）CPU及其配套的芯片便宜、遍及、通用，用這套芯片制成的PC，給維修及推廣遍及帶來方便。Z80有獨(dú)立的輸入/輸出指令,并且指令款式較短，實行時間也較短，如許有利于掃描周期的收縮。Z80輸入/輸出指令款式較短，相應(yīng)的輸入/輸出設(shè)置裝備擺設(shè)編碼也較短，以是相應(yīng)的譯碼硬件器較簡樸。由于Z80的信息是接納輸入/輸出映射方法，因而計劃流步伐時，對輸入/輸出與存儲器尋址容易區(qū)別。
②用單片機(jī)作CPU
自從1974年出現(xiàn)單片機(jī)以來，已有不少產(chǎn)品接納單片機(jī)做可編步伐控制器。日本三菱F系列PLC就接納美PLCINTEL公司MES－48系列的單片機(jī)8049和8039做處置處罰器，8039單片機(jī)在一塊電影上集成了8位的CPU，1288的數(shù)據(jù)存儲器。27條輸入/輸出線，T0、T1、INT測試線及8位定時器/計數(shù)器，時鐘振蕩電路等。
自80年月以來，出現(xiàn)了集成度更高。功效更強(qiáng)，并帶有“布爾機(jī)”而又便于作數(shù)據(jù)通訊的MCS-51系列單片機(jī)以及功效更高的16位單片機(jī)，大有代替MCS－48系列之勢。日本三菱的F2系列PLC即接納CPU8031。MCS－51系列單片機(jī)是美PLCINTEL公司在MCS－48單片機(jī)底子上，于80年月初推出的產(chǎn)品，具有高集成度、高可靠性、高功效、高速率、低代價等特點(diǎn)。它有三個代表產(chǎn)品：8051、8751和8031，它們分別有差別的應(yīng)用特性。8051因此4K字節(jié)EPR0M代替4K字節(jié)的R0M的8051； 8031是內(nèi)部無R0M8051。必須外接EPR0M；INTEL公司的96系列的單片機(jī)，字長為16，運(yùn)算速率比51系列更高，這必將為高等次的PLC開辟和應(yīng)用帶來優(yōu)美的遠(yuǎn)景。用單片機(jī)制成的PLC有以下明顯特點(diǎn)：為機(jī)電設(shè)置裝備擺設(shè)一體化創(chuàng)造了條件，由于由單片機(jī)制成PLC，體積更小。同時PLC邏輯功效很強(qiáng)，并且具有數(shù)值運(yùn)算和通訊接口。
③用位片衰落處置處罰器作CPU
位片衰落處置處罰器的重要特點(diǎn)是：速率快、機(jī)動性強(qiáng)、服從高等特點(diǎn)�？梢耘e行“級聯(lián)”，易于“流水線”操縱。
