描述

由于PLC強大的功能和優(yōu)良的性能，以及應(yīng)用成本的不斷下降和使用的方便性，促使PLC的應(yīng)用領(lǐng)域不斷擴展，市場潛力巨大，于是，全世界許多公司紛紛推出自己的PLC產(chǎn)品。出于壟斷或市場保護的目的，各家公司的PLC產(chǎn)品各有差別，互不兼容。當形形色色的PLC涌入市場時，國際電工委員會與有關(guān)PLC制造商多次協(xié)商，于1993年制定了IEC1131標準以引導(dǎo)PLC健康地發(fā)展。

IEC1131標準共分為5個部分：IEC1131-1為一般信息，即對通用邏輯編程作了一般性介紹并討論了邏輯編程的基本概念、術(shù)語和定義；IEC1131-2為裝配和測試需要，從機械和電氣兩部分介紹了邏輯編程對硬件設(shè)備的要求和測試需要；IEC1131-3為編程語言的標準，它吸取了多種編程語言的長處，并制定了5種標準語言；IEC1131-4為用戶指導(dǎo)，提供了有關(guān)選擇、安裝、維護的信息資料和用戶指導(dǎo)手冊；IEC1131-5為通信規(guī)范，規(guī)定了邏輯控制設(shè)備與其他裝置的通信聯(lián)系規(guī)范。IEC1131標準后更名為IEC61131標準。
