TSXDEY16A4施耐德模塊
梯形圖的設(shè)定可以分為兩部分：輸入信號(hào)的捕獲和輸出信號(hào)的驅(qū)動(dòng)。輸入信號(hào)的捕獲發(fā)生在梯形圖的頂部，可以是傳感器的信號(hào)或者其他控制輸入的信號(hào)。輸出信號(hào)的驅(qū)動(dòng)發(fā)生在梯形圖的底部，可以是控制器輸出的信號(hào)或者其他控制輸出的信號(hào)。
邏輯操作可以按照設(shè)計(jì)要求在水平線路上設(shè)置，例如在控制輸出前需要檢查輸入狀態(tài)是否正確以及信號(hào)之間的邏輯關(guān)系和時(shí)序關(guān)系等等。
PLC梯形圖的時(shí)序圖，是指用時(shí)序圖來(lái)描述 PLC 梯形圖中各部分圖形之間的時(shí)序關(guān)系。
在 PLC 控制系統(tǒng)中，PLC 梯形圖是最常用的表示形式之一。它可以描述輸入輸出的關(guān)系和邏輯運(yùn)算的過(guò)程，以及各個(gè)事件和任務(wù)之間的邏輯關(guān)系。而時(shí)序圖則可以清晰地表示各部分圖形之間的時(shí)間關(guān)系和時(shí)序流程，因此，在 PLC 控制系統(tǒng)的設(shè)計(jì)中，時(shí)序圖被廣泛應(yīng)用于 PLC 梯形圖的表達(dá)和設(shè)計(jì)。
