 可編程控制器（PLC）具有結(jié)構(gòu)靈巧，硬件配置靈活方便、可靠性高、抗*力強，易學(xué)易用的特點，已作為普遍的自動化控制器件廣泛應(yīng)用于各行各業(yè)。《PLC原理及應(yīng)用》課程已成為工科院校一門覆蓋面較廣的專業(yè)課，作為學(xué)校如何培養(yǎng)出高素質(zhì)應(yīng)用型PLC人才，這成為社會、學(xué)校、教師與家長關(guān)注的焦點。根據(jù)多年的教學(xué)實踐，就影響PLC人才培養(yǎng)的各個因素的提高與協(xié)同，我提出以下幾點建議以供參考： 

    一、教學(xué)與實習(xí)設(shè)備投入。在PLC課程的實踐教學(xué)中，應(yīng)把機械、電工、電子、液壓、氣動和計算機等知識與PLC技術(shù)進(jìn)行有機地，擴大實習(xí)實訓(xùn)課時的比重，逐步加大學(xué)校相關(guān)設(shè)備的投入，建立較為完備的PLC技術(shù)仿真實訓(xùn)室，從而為“PLC仿真項目開發(fā)"的實訓(xùn)教學(xué)創(chuàng)造良好條件。教學(xué)實踐證明，只有通過PLC仿真項目方面的實訓(xùn)，讓學(xué)生親自編程、實際接線和仿真調(diào)試，并對運行過程中所遇到的問題進(jìn)行分析和改進(jìn)，才能真正培養(yǎng)學(xué)生創(chuàng)新思維和綜合職業(yè)能力，真正實現(xiàn)學(xué)生畢業(yè)后在PLC技術(shù)應(yīng)用領(lǐng)域“*上崗"的zui終教學(xué)目標(biāo)。

二、理論、實驗與實訓(xùn)教學(xué)。任何課程教學(xué)活動的首要任務(wù)都是激發(fā)學(xué)生的學(xué)習(xí)興趣，同樣在PLC教學(xué)中激發(fā)學(xué)生的興趣并不難，重要的是讓學(xué)生不斷地提高，不斷地體驗到成功的喜悅，這樣才能始終保持其濃厚的興趣。

     1、理論課的首要任務(wù)是讓學(xué)生明確PLC是什么？PLC能做什么？怎么做？教師可以通過一個簡單、形象實例（如：電機的長動控制）的完整講解、操作與演示，先讓學(xué)生了解PLC控制系統(tǒng)包括主電路與控制電路，PLC的外部硬件連線與內(nèi)部軟件編程兩個基本的環(huán)節(jié)僅僅充當(dāng)控制電路部分，讓學(xué)生整體了解PLC控制系統(tǒng)的構(gòu)成與工作過程，再以此為基礎(chǔ)進(jìn)行外部硬件連線與內(nèi)部軟件編程兩個基本環(huán)節(jié)的深入講解，這樣便于學(xué)生對比繼電接觸器控制系統(tǒng)對本課程的整體把握，明確課程的中心任務(wù)，有了目標(biāo)也就有了學(xué)習(xí)的動力。
