良好的接地是抑制噪聲干擾和電壓沖擊保證PLC可靠工作的重要條件。PLC系統(tǒng)接地的基本原則是單點(diǎn)接地，一般用獨(dú)自的接地裝置，單獨(dú)接地，接地線應(yīng)盡量短，一般不超過20m，使接地點(diǎn)盡量靠近PLC。
有些PLC控制既有"手動(dòng)控制"又有"自動(dòng)控制"，而自動(dòng)控制程序和手動(dòng)控制程序不會(huì)同時(shí)執(zhí)行，這時(shí)可將自動(dòng)與手動(dòng)信號(hào)按不同控制狀態(tài)要求分組接入PLC輸入端子，如圖1所示(本文以三菱FX2小型PLC編號(hào)分配為例進(jìn)行梯形圖設(shè)計(jì))。
變頻器的VC控制方式的做法是將異步電動(dòng)機(jī)在三相坐標(biāo)系下的定子電流Ia、Ib、Ic、通過三相－二相變換，等效成兩相靜止坐標(biāo)系下的交流電流Ia1Ib1，再通過按轉(zhuǎn)子磁場(chǎng)定向旋轉(zhuǎn)變換，等效成同步旋轉(zhuǎn)坐標(biāo)系下的直流電流Im1、It1(Im1相當(dāng)于直流電動(dòng)機(jī)的勵(lì)磁電流；
一個(gè)程序編好后要把它輸入PLC中，過去用的較多的是手持編程器，要人工輸入，比較麻煩，容易出錯(cuò)。近年來年隨著計(jì)算機(jī)的普及，已逐漸被各種編程軟件所取代。例如三菱公司的FXG-P，歐姆公司的CX-PROGRAMMER。西門子公司的STEP-7-MICRO-WIN32等。這些工具軟件都可以在WINDOWS的環(huán)境下運(yùn)行，用起來很方便，當(dāng)你選定了一個(gè)廠家PLC后，一定要學(xué)會(huì)使用它的編程軟件，因?yàn)檫@將極大的節(jié)約你的編程和調(diào)試時(shí)間.

功能表圖語言和語句描述語言是高級(jí)的程序設(shè)計(jì)語言，它可根據(jù)需要去執(zhí)行更有效的操作，例如，模擬量的控制，數(shù)據(jù)的操縱，報(bào)表的報(bào)印和其他基本程序設(shè)計(jì)語言無法完成的功能。
這類故障一般是由于變頻器運(yùn)行參數(shù)設(shè)定不合適，或外部工況、條件不滿足變頻器使用要求所產(chǎn)生的一種保護(hù)動(dòng)作現(xiàn)象；另一類是由于使用環(huán)境惡劣，高溫、導(dǎo)電粉塵引起的短路、潮濕引起的絕緣降低或擊穿等突發(fā)故障(嚴(yán)重時(shí)，會(huì)出現(xiàn)打火、爆炸等異?，F(xiàn)象)。這類故障發(fā)生后，一般會(huì)使變頻器無任何顯示，其處理方法是先對(duì)變頻器解體檢查，重點(diǎn)查找損壞件，根據(jù)故障發(fā)生區(qū)，進(jìn)行清理、測(cè)量、更換，然后全面測(cè)試，再恢復(fù)系統(tǒng)，空載試運(yùn)行，觀察觸發(fā)回路輸出側(cè)的波形，當(dāng)6組波形大小、相位差相等后，再加載運(yùn)行，達(dá)到解決故障的目的。本文主要闡述第二類故障的分析和處理方法
邏輯設(shè)計(jì)法的優(yōu)點(diǎn)是能獲得理想、經(jīng)濟(jì)的方案，但這種方法設(shè)計(jì)難度較大，整個(gè)設(shè)計(jì)過程較復(fù)雜，還要涉及一些新概念，因此，在一般常規(guī)設(shè)計(jì)中，很少單獨(dú)采用。其具體設(shè)計(jì)過程可參閱專門論述資料，這里不再作進(jìn)一步介紹
