描述
輸入/輸出點(diǎn) 輸入點(diǎn)是與機(jī)床側(cè)被控對(duì)象有關(guān)的按鈕、開(kāi)關(guān)、繼電器和接觸器觸點(diǎn)等連接的輸入信號(hào)接口,以及由機(jī)床側(cè)直接連接到NC的輸入信號(hào)接口(如減速信號(hào):*DECX,*DECY…,跳過(guò)信號(hào):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(hào)的接口。設(shè)計(jì)者對(duì)被控對(duì)象的上述I/O信號(hào)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。
