由于各PLC廠家產(chǎn)品在指令系統(tǒng)上的差異及編程方法上用戶要求不同,近年來IEC制訂了基于Windows的編程語(yǔ)言標(biāo)準(zhǔn)IEC61131-3(1993年IEC頒布可編程序控制器的國(guó)際標(biāo)準(zhǔn)IEC1131),它規(guī)定了指令表(IL)、梯形圖(LD)、順序功能圖(SFC)、功能塊圖(FBD)、結(jié)構(gòu)化文本(ST)五種編程語(yǔ)言。這包括了文本化編程(IL、ST)和圖形編程(LD、FBD)兩個(gè)方面,而SFC則在兩類編程語(yǔ)言中均可使用。IEC技術(shù)委員會(huì)(TC65)進(jìn)來開展了 IEC61499項(xiàng)目,將IEC61131-3進(jìn)行了擴(kuò)展,它是針對(duì)通過通信網(wǎng)絡(luò)互聯(lián)的模塊化分布系統(tǒng)的體系結(jié)構(gòu)的標(biāo)準(zhǔn),將對(duì)IEC61131-3有所改善。這是以數(shù)字技術(shù)為基礎(chǔ)的可編程序邏輯控制裝置在高層次上走向開放性的標(biāo)準(zhǔn)化文件,是PLC發(fā)展的一大趨勢(shì)。
