可依據(jù)運(yùn)用請(qǐng)求，合理選用智能型輸入輸出模塊，以便行進(jìn)操控水平緩下降運(yùn)用本錢。 
    思考是不是需求拓展機(jī)架或長(zhǎng)途I/O機(jī)架等。 
    (三)電源的挑選
    PLC的供電電源，除了引進(jìn)設(shè)備時(shí)一起引進(jìn)PLC應(yīng)依據(jù)商品闡明書請(qǐng)求規(guī)劃和選用外，通常PLC的供電電源應(yīng)規(guī)劃選用220VAC電源，與國(guó)內(nèi)電網(wǎng)電壓共同。首要的運(yùn)用場(chǎng)合，應(yīng)選用不間斷電源或穩(wěn)壓電源供電。 
    假如PLC自身帶有可運(yùn)用電源時(shí)，應(yīng)核對(duì)供給的電流是不是滿意運(yùn)用請(qǐng)求，不然應(yīng)規(guī)劃外接供電電源。為防止外部高壓電源因誤操作而引進(jìn)PLC，對(duì)輸入和輸出信號(hào)的阻隔是必要的，有時(shí)也可選用簡(jiǎn)略的二極管或熔絲管阻隔。 
    (四)存儲(chǔ)器的挑選 
    因?yàn)楹怂銠C(jī)集成芯片技能的開展，存儲(chǔ)器的報(bào)價(jià)已下降，因此，為保證運(yùn)用項(xiàng)意圖正常投運(yùn)，通常請(qǐng)求PLC的存儲(chǔ)器容量，按256個(gè)I/O點(diǎn)至少選8K存儲(chǔ)器挑選。需求雜亂操控功用時(shí)，應(yīng)挑選容量更大，層次更高的存儲(chǔ)器。 
    (五)冗余功用的挑選 
    1．操控單元的冗余
    (1)首要的進(jìn)程單元：CPU（包含存儲(chǔ)器）及電源均應(yīng)1B1冗余。 
    (2)在需求時(shí)也可選用PLC硬件與熱備軟件構(gòu)成的熱備冗余體系、2重化或3重化冗余容錯(cuò)體系等。
    2．I/O接口單元的冗余 
    (1)操控回路的多點(diǎn)I/O卡應(yīng)冗余裝備。
    (2)首要檢查點(diǎn)的多點(diǎn)I/O卡可冗余裝備。3）依據(jù)需求對(duì)首要的I/O信號(hào)，可選用2重化或3重化的I/O接口單元。
    (六)經(jīng)濟(jì)性的思考
    挑選PLC時(shí)，應(yīng)思考功用報(bào)價(jià)比。思考經(jīng)濟(jì)性時(shí)，應(yīng)一起思考運(yùn)用的可拓展性、可操作性、投入產(chǎn)出比等因素，進(jìn)行對(duì)比和兼顧，終究選出較滿意的商品。
