摘要
可編程序控制器作為一種工業(yè)控制計算機(jī)，其最大特點是“可編程”， 即突出了軟件的柔性控制思想。與其它控制設(shè)備相比較，它具有功能完善、擴(kuò)展靈活和可靠性高等明顯優(yōu)勢，目前已成為工業(yè)生產(chǎn)控制領(lǐng)域中最常見最重要的核心裝置。
本文結(jié)合可遍程序控制器的應(yīng)用現(xiàn)狀，分析了它的基本原理與實現(xiàn)方式，提出了一種基于通用微機(jī)（工控PC機(jī)）ISA總線技術(shù)開發(fā)的智能化嵌入式可編程序控制器系統(tǒng)設(shè)計方案，并且詳細(xì)說明了組成系統(tǒng)的硬件電路設(shè)計；同時針對梯形圖編輯軟件專用性太強(qiáng)的現(xiàn)況，順應(yīng)控制領(lǐng)域開發(fā)化的潮流，設(shè)計了梯形圖集成開發(fā)環(huán)境，著重論述了梯形圖程序的編輯、編譯部分。

ABSTRACT
Programmable Logic Controller(PLC) is a kind of industrial control computer, the most important feature is “programmable”, which gives prominence to the idea of software’s flexible control. Compared with other control equipment, PLC possesses many advantages such as perfect function, convenient expand and high reliability etc, and at present becomes the most important and the widely used center device.
Combined with application actuality, the elemental principle and effectuation mode of PLC are analyzed in details in this thesis, and based on ISA technique of microcomputer or industrial control PC a design plan of intelligent embedded PLC system is presented as well. The author also explains the system hardware circuit design in detail. At the same time, in order to conform the opening tendency of control filed and solve the problem that ladder diagram software is narrowly limited to special purpose, in this thesis the edit, compile part of ladder program are emphatically discussed.
