不同型號的PLC具有不同的硬件組成和性能指標。它們的基本I/O點數(shù)和擴展范圍,程序存儲容量往往差別很大。因此,在進行PLC程序設計之前,要對所用PLC的型號,硬件配置(如內裝型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 輸入點是與機床側被控對象有關的按鈕、開關、繼電器和接觸器觸點等連接的輸入信號接口,以及由機床側直接連接到NC的輸入信號接口(如減速信號:*DECX,*DECY…,跳過信號:SKIP等)。
輸出點包括向機床側繼電器,指示燈等輸出信號的接口。設計者對被控對象的上述I/O信號要逐一確認,并分別計算出總的需要數(shù)量。選用的PLC所具有的I/O點數(shù)應比計算出的 I/O點數(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)模隨機床的復雜程度變化,設計者要根據(jù)具體任務對程序規(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的處理時間,指令功能,定時器、計數(shù)器、內部繼電器的技術規(guī)格、數(shù)量等指標也應滿足要求。
