题目：一种PLC的程序设计新方法A new approach to PLC software design
字数：中文6040字
摘要：
本文描述的是PLC软件开发的一种基本方法。其本质是采用一种被称为程序——图表语言的新型程序建模语言。这种语言与传统方法的区别在于其对控制系统程序方面的处理方式且允许软件处于一个更高的技术规格。此建模语言适用于图形模拟软件和自动代码生成软件工具的研发。这种符号技术规范已试用于工业应用软件的开发，且已经过实验室环境的测试。
关键词：过程控制；软件规范；软件工程
英文摘要：
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
