描述
狀態(tài)顯示LED指示燈共有4盞，其中，PWR（綠色）為電源的通斷指示用，電源接通時亮，電源斷開時滅；RUN（綠色）為PLC工作狀態(tài)指示用，PLC處在運行或監(jiān)控狀態(tài)時亮，處在編程狀態(tài)或運行異常時滅；COMM（橙色）為通信指示，PLC通過外設端口與外部設備通信時頻繁閃爍，不通信時熄滅；ERR/ALM（紅色）為錯誤/警告指示，當PLC出現(xiàn)致命性錯誤或非致命性錯誤時亮，兩者共用一盞指示燈作狀態(tài)指示用，不同之處在于：當PLC出現(xiàn)致命性錯誤時該指示燈亮并停止程序的運行；而當PLC出現(xiàn)非致命性錯誤（警告）時該指示燈閃爍，但PLC并不停止程序的運行，仍能維持工作。正常時（也就是既沒有錯誤也沒有警告時）該指示燈自動熄滅。
兩個模擬量設定電位器0、1位于面板中部的左側(cè)（見圖2-19），可預置參數(shù)，范圍為0～200(BCD)。
外設端口可以連接編程器，也可以通過RS232C或RS422通信適配器，連接PLC或上位計算機，構成網(wǎng)絡。
