EPRO PR6423/013-020序執(zhí)行階段。在執(zhí)行用戶(hù)程序過(guò)程中，PLC按照梯形圖程序掃描原則，一般來(lái)說(shuō)，PLC按從左至右、從上到下的步驟逐個(gè)執(zhí)行程序。但遇到程序跳轉(zhuǎn)指令，則根據(jù)跳轉(zhuǎn)條件是否滿(mǎn)足來(lái)決定程序跳轉(zhuǎn)地址。程序執(zhí)行過(guò)程中，當(dāng)指令中涉及輸入、輸出狀態(tài)時(shí)，PLC就從輸入映像寄存器中“讀入"對(duì)應(yīng)輸入端子狀態(tài)，從輸出映像寄存器“讀入"對(duì)

 PLC的外部接線圖后，同時(shí)也確定了PLC的各輸入信號(hào)和輸出負(fù)載對(duì)應(yīng)的輸入繼電器和輸出繼電器的元件號(hào)。例如圖2中控制搖臂上升的按鈕SB3接在PLC的X0輸入端子上，該控制信號(hào)在梯形圖中對(duì)應(yīng)的輸入繼電器的元件號(hào)X0。在梯形圖中，可以將X0的觸點(diǎn)想象為SB3的觸點(diǎn)。確定與繼電器電路圖的中間繼電器、時(shí)間繼電路對(duì)應(yīng)的梯形圖中的輔助繼電器（M）和定時(shí)器（T）的元件號(hào)。繼電器電路圖中的元件和梯形圖中的元件號(hào)之間的對(duì)應(yīng)關(guān)系。為梯形圖的設(shè)計(jì)打下了基礎(chǔ)。
