 FX系列PLC梯形圖中的編程元件的名稱有字母和數(shù)字組成，他們分別表示元件的類型和元件號(hào)，如Y10，M129。輸入繼電器與輸出繼電器的元件號(hào)用八進(jìn)制數(shù)表示，八進(jìn)制數(shù)只有0~7這8個(gè)數(shù)字符號(hào)，遵循“逢8進(jìn)1”的運(yùn)算規(guī)則。例如，八進(jìn)制數(shù)X17和X20是兩個(gè)相鄰的整數(shù)。表3–3給出了FX2N系列PLC的輸入/輸出繼電器元件號(hào)。


1．輸入繼電器(X)  
 輸入繼電器是PLC接收外部輸入的開關(guān)量信號(hào)的窗口。PLC通過光耦合器，將外部信號(hào)的狀態(tài)讀入并存儲(chǔ)在輸入映像寄存器中。輸入端可以外接常開觸點(diǎn)或常閉觸點(diǎn)，也可以接多個(gè)觸點(diǎn)組成的串并聯(lián)電路或電子傳感器(如接近開關(guān))。在梯形圖中，可以多次使用輸入繼電器的常開觸點(diǎn)和常閉觸點(diǎn)。  
 圖3–6是一個(gè)PLC控制系統(tǒng)的示意圖，X0端子外接的輸入電路接通時(shí)，它對(duì)應(yīng)的輸入映像寄存器為1狀態(tài)，斷開時(shí)為0狀態(tài)。輸入繼電器的狀態(tài)惟一地取決于外部輸入信號(hào)的狀態(tài)，不可能受用戶程序的控制，因此在梯形圖中絕對(duì)不能出現(xiàn)輸入繼電器的線圈。

因?yàn)镻LC只是在每一掃描周期開始時(shí)讀取輸入信號(hào)，輸入信號(hào)為ON或OFF的持續(xù)時(shí)間應(yīng)大于PLC的掃描周期。如果不滿足這一條件，可能會(huì)丟失輸入信號(hào)。
 2. 輸出繼電器(Y)
 輸出繼電器是PLC向外部負(fù)載發(fā)送信號(hào)的窗口。輸出繼電器用來將PLc的輸出信號(hào)傳
送給輸出模塊，再由后者驅(qū)動(dòng)外部負(fù)載。如果圖3-6梯形圖中Y4的線圈“通電”，繼電器型輸出模塊中對(duì)應(yīng)的硬件繼電器的常開觸點(diǎn)閉合，使外部負(fù)載工作。輸出模塊中的每一個(gè)硬件繼電器僅有一對(duì)常開觸點(diǎn)，但是在梯形圖中，每一個(gè)輸出繼電器的常開觸點(diǎn)和常閉觸點(diǎn)都可以多次使用。
