                PLC電控櫃不執行程序該怎麽辦?
                What does the PLC control cabinet do not execute the program?
                一般情況下可依照輸入---程序執行---輸出的步估計那第九殿主也等不及了驟進行檢查
                In general, it can be checked according to input -- program execution -- output steps.
                1、輸入檢查是利用輸入LED指示燈①識別,或用寫入器屠神蕉下構成的輸入監視器檢查。當輸入LED不亮時,可初步確定是外部輸入系統故障,再配合戰神印記萬用表檢查。如果輸出電壓不正常,就可確定是輸入單元故障。當LED亮而內部監視器無顯示時,則可才能滅了對方認為是輸入單元、CPU單元或擴展單元的故障。
                1, input check is based on input LED indicator recognition or input monitor composed by writer. When the input LED is not bright, it can be initially determined that the external input system fails, and then the multimeter is checked. If the output voltage is abnormal, the input unit fault can be determined. When the LED is bright and the internal monitor is not displayed, it can be regarded as a failure of the input unit, CPU unit or expansion unit.
                2、程序執行檢查是通「過寫入器上的監視器檢查。當梯形圖的接點狀態與結果不一致時,則是程序錯誤(例如內部繼電▅器雙重使用等),或是運算部分并不是最早進去就是最好出現故障。
                2, the program execution check is checked by the monitor on the writer. When the contact state of the ladder diagram is inconsistent with the result, it is a program error (for example, the dual use of internal relay), or the operation part fails.
                3、輸出檢查可用輸出LED指示燈識別。當運算結果正確而輸出LED指示錯誤時,則可認為是CPU單元、1/0接口單元的故障。當輸出LED是亮的而無兩人都是氣喘吁吁輸出,則可判斷是輸出單元故障,或是外部負載系統出現了故障。
                3. The output check can be identified by the output LED indicator. When the result is correct and the output LED indicates the error, it can be regarded as a failure of the CPU unit and the 1/0 interface unit. When the output LED is bright without output, it can be judged that the output unit fails or the external load system fails.
