描述

不同型號的PLC具有不同的硬件組成和性能指標(biāo)。它們的基本I／O點(diǎn)數(shù)和擴(kuò)展范圍，程序存儲容量往往差別很大。因此，在進(jìn)行PLC程序設(shè)計(jì)之前，要對所用PLC的型號，硬件配置（如內(nèi)裝型PLC是否要增加附加I／O板，通用型PLC是否要增加I／O模板等）作出選擇。
（1）輸入／輸出點(diǎn)輸入點(diǎn)是與機(jī)床側(cè)被控對象有關(guān)的按鈕、開關(guān)、繼電器和接觸器觸點(diǎn)等連接的輸入信號接口，以及由機(jī)床側(cè)直接連接到NC的輸入信號接口（如減速信號：*DECX，*DECY…，跳過信號：SKIP等）。
輸出點(diǎn)包括向機(jī)床側(cè)繼電器，指示燈等輸出信號的接口。設(shè)計(jì)者對被控對象的上述I／O信號要逐一確認(rèn)，并分別計(jì)算出總的需要數(shù)量。選用的PLC所具有的I／O點(diǎn)數(shù)應(yīng)比計(jì)算出的I／O點(diǎn)數(shù)稍多一些，以備可能追加和變更控制性能的需要。
（2）存儲容量一般來說，普通CNC車床順序程序的規(guī)模約1000步，小型加工中心約2000步。程序規(guī)模隨機(jī)床的復(fù)雜程度變化，設(shè)計(jì)者要根據(jù)具體任務(wù)對程序規(guī)模作出估算，并據(jù)此確定合理的存儲容量。
另外，所選擇PLC的處理時(shí)間，指令功能，定時(shí)器、計(jì)數(shù)器、內(nèi)部繼電器的技術(shù)規(guī)格、數(shù)量等指標(biāo)也應(yīng)滿足要求。
