2.設(shè)計思路本文提出的4種簡易設(shè)計方法都是先設(shè)計步進(jìn)階梯,在步進(jìn)階梯實(shí)現(xiàn)由轉(zhuǎn)步主令信號控制輔助繼電器得失電;然后根據(jù)步進(jìn)階梯設(shè)計輸出階梯,在輸出階梯實(shí)現(xiàn)由輔助繼電器控制輸出繼電器得失電。這4種設(shè)計法所設(shè)計的梯形圖電路結(jié)構(gòu)及相應(yīng)的指令應(yīng)適用于大多數(shù)PLC機(jī)型,具有通用性。
由于各種PLC機(jī)型的編程元件代號及其編號不盡相同,為便于闡述,本文約定:所有梯形圖中的輸入繼電器、輸出繼電器、輔助繼電器(又稱內(nèi)部繼電器)的代號分別為:X、Y、M。設(shè)計中所用到的某些功能指令,如置位指令約定為S×,復(fù)位指令為R×;移位指指令為SR×。其中的“×”表示編程元件的編號,用十進(jìn)制數(shù)表示。用這些方法設(shè)計實(shí)際的控制系統(tǒng)時,應(yīng)將編程元件代號和編號變換成所選用的PLC機(jī)型對應(yīng)的代號和編號。
