文字符號分為基本文字符號和輔助文字符號。文字符號適用于電氣技術(shù)領(lǐng)域中技術(shù)文件的編制，也可表示在電氣設(shè)備、裝置和元件上或其近旁以標(biāo)明它們的名稱、功能、狀態(tài)和特征
PLC采用循環(huán)掃描的工作方式，在PLC中用戶程序按先后順序存放，CPU從第一條指令開始執(zhí)行程序，直到遇到結(jié)束符后又返回第一條，如此周而復(fù)始不斷循環(huán)。PLC的掃描過程分為內(nèi)部處理、通信操作、程序輸入處理、程序執(zhí)行、程序輸出幾個(gè)階段。

變頻器通電后無顯示，也是較常見的故障現(xiàn)象之一，引起這類故障原因，多數(shù)也是由于開關(guān)電源的損壞所致。如MF系列變頻器的開關(guān)電源采用的是較常見的反激式開關(guān)電源控制方式，開關(guān)電源的輸出級電路發(fā)生短路也會(huì)引起開關(guān)電源損壞，從而導(dǎo)致變頻器無顯示。
用編程軟件將輸出點(diǎn)強(qiáng)制ON/OFF，觀察對應(yīng)的控制柜內(nèi)PLC負(fù)載（指示燈、接觸器等）的動(dòng)作是否正常，或?qū)?yīng)的接線端子上的輸出信號的狀態(tài)變化是否正確。
