FX系列PLC梯形圖中的編程元件的名稱有字母和數字組成,，他們分別表示元件的類型和元件號,，如Y10，M129,。輸入繼電器與輸出繼電器的元件號用八進制數表示,，八進制數只有0~7這8個數字符號，遵循“逢8進1”的運算規(guī)則,。例如,，八進制數X17和X20是兩個相鄰的整數。表3–3給出了FX_2N系列PLC的輸入/輸出繼電器元件號,。

1．輸入繼電器(X)  

 輸入繼電器是PLC接收外部輸入的開關量信號的窗口,。PLC通過光耦合器，將外部信號的狀態(tài)讀入并存儲在輸入映像寄存器中,。輸入端可以外接常開觸點或常閉觸點,，也可以接多個觸點組成的串并聯(lián)電路或電子傳感器(如接近開關)。在梯形圖中,，可以多次使用輸入繼電器的常開觸點和常閉觸點,。  

 圖3–6是一個PLC控制系統(tǒng)的示意圖，X0端子外接的輸入電路接通時,，它對應的輸入映像寄存器為1狀態(tài),，斷開時為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的狀態(tài),，不可能受用戶程序的控制,，因此在梯形圖中絕對不能出現(xiàn)輸入繼電器的線圈。

因為PLC只是在每一掃描周期開始時讀取輸入信號,，輸入信號為ON或OFF的持續(xù)時間應大于PLC的掃描周期,。如果不滿足這一條件，可能會丟失輸入信號,。

 2. 輸出繼電器(Y)

 輸出繼電器是PLC向外部負載發(fā)送信號的窗口,。輸出繼電器用來將PLc的輸出信號傳

送給輸出模塊,，再由后者驅動外部負載。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應的硬件繼電器的常開觸點閉合,，使外部負載工作。輸出模塊中的每一個硬件繼電器僅有一對常開觸點,，但是在梯形圖中,，每一個輸出繼電器的常開觸點和常閉觸點都可以多次使用。
