摘要：
本文描述的是PLC軟件開發(fā)的一種基本方法。其本質(zhì)是采用一種被稱為程序——圖表語言的新型程序建模語言。這種語言與傳統(tǒng)方法的區(qū)別在于其對(duì)控制系統(tǒng)程序方面的處理方式且允許軟件處于一個(gè)更高的技術(shù)規(guī)格。此建模語言適用于圖形模擬軟件和自動(dòng)代碼生成軟件工具的研發(fā)。這種符號(hào)技術(shù)規(guī)范已試用于工業(yè)應(yīng)用軟件的開發(fā)，且已經(jīng)過實(shí)驗(yàn)室環(huán)境的測(cè)試。

Abstract
This paper presents a model-based approach to PLC software development. The essence of this approach is the
introduction of a new procedural modeling language called ProcGraph. In contrast to commonly used methods, Proc-
Graph deals with the procedural aspect of the control system and allows software specification at a higher level of
abstraction. The modeling language has been supported with the development of a software tool which facilitates
graphical model design and automatic code generation. The specification notation has been tested in the development
of software for industrial applications. The supporting tool has been tested in a laboratory environment. © 2003
