描述
在學(xué)習(xí)初始階段首先要弄清PLC的內(nèi)部結(jié)構(gòu)與選型方法,并牢記PLC在實(shí)際使用當(dāng)中的禁忌。隨后用心學(xué)習(xí)理解吸收PLC的基本語(yǔ)句和梯形圖的編程方法。無(wú)論三菱還是西門子亦或國(guó)內(nèi)各品牌PLC其官網(wǎng)都提供免費(fèi)的編程軟件,好一些的還有在線仿真軟件提供,便于沒(méi)有PLC實(shí)物的學(xué)習(xí)者模擬學(xué)習(xí)。該階段我們可以將一些常用的電氣線路圖如正反轉(zhuǎn)、Y/△啟動(dòng)等線路用PLC梯形圖的方式編寫并加以仿真。
