二、存儲(chǔ)器容量的預(yù)算 
    存儲(chǔ)器容量是可編程序操控器自身能供給的硬件存儲(chǔ)單元巨細(xì)，程序容量是存儲(chǔ)器中用戶運(yùn)用項(xiàng)目運(yùn)用的存儲(chǔ)單元的巨細(xì)，因此程序容量小于存儲(chǔ)器容量。規(guī)劃階段，因?yàn)橛脩暨\(yùn)用程序還未編制，因此，程序容量在規(guī)劃階段是不知道的，需在程序調(diào)試以后才知道。為了規(guī)劃選型時(shí)能對(duì)程序容量有必定預(yù)算，通常選用存儲(chǔ)器容量的預(yù)算來代替。
 
    存儲(chǔ)器內(nèi)存容量的預(yù)算沒有固定的公式，許多文獻(xiàn)材料中給出了不一樣公式，大體上都是按數(shù)字量I/O點(diǎn)數(shù)的10～15倍，加上模仿I/O點(diǎn)數(shù)的100倍，以此數(shù)為內(nèi)存的總字?jǐn)?shù)（16位為一個(gè)字），別的再按此數(shù)的25%思考余量。 
    三、操控功用的挑選
    該挑選包含運(yùn)算功用、操控功用、通訊功用、編程功用、確診功用和處理速度等特性的挑選。 
    (一)運(yùn)算功用 
    簡(jiǎn)略PLC的運(yùn)算功用包含邏輯運(yùn)算、計(jì)時(shí)和計(jì)數(shù)功用；通常PLC的運(yùn)算功用還包含數(shù)據(jù)移位、對(duì)比等運(yùn)算功用；較雜亂運(yùn)算功用有代數(shù)運(yùn)算、數(shù)據(jù)傳送等；大型PLC中還有模仿量的PID運(yùn)算和別的高檔運(yùn)算功用。跟著敞開體系的呈現(xiàn)，如今在PLC中都已具有通訊功用，有些商品具有與下位機(jī)的通訊，有些商品具有與同位機(jī)或上位機(jī)的通訊，有些商品還具有與工廠或企業(yè)網(wǎng)進(jìn)行數(shù)據(jù)通訊的功用。規(guī)劃選型時(shí)應(yīng)從實(shí)踐運(yùn)用的請(qǐng)求動(dòng)身，合理選用所需的運(yùn)算功用。大大都運(yùn)用場(chǎng)合，只需求邏輯運(yùn)算和計(jì)時(shí)計(jì)數(shù)功用，有些運(yùn)用需求數(shù)據(jù)傳送和對(duì)比，當(dāng)用于模仿量檢查和操控時(shí)，才運(yùn)用代數(shù)運(yùn)算，數(shù)值改換和PID運(yùn)算等。要顯現(xiàn)數(shù)據(jù)時(shí)需求譯碼和編碼等運(yùn)算。
