可视化的PLC程序使用XML
摘要:由于P LC程序日益复杂,在PLC应用方面有越来越多的兴趣爱好者。形式化方法,让僵化的证明系统属性被核查和验证。一个传统思路的方法就是在PLC编程中设立一个正式的设计方法。不过,现有的软件已被优化,改变,或移植到新系统.有需要找到从某一PLC程序开始的方法。因此,规范PLC程序是一个现在研究的热点。该文章概述了基于形式化的PLC程序基础上从新启动的方法。转型成为一个独立的格式和可视化的结构,在这个过程中,PLC程序的确定是作为这项措施的重要中间步骤。这表明如何XML和相应的技术可用于形式化和可视化现有的PLC程序。
Visualization of PLC Programs using XML
Abstract - Due to the growing complexity of PLC programs there is an increasing interest in the application of formal methods in this area. Formal methods allow rigid proving of system properties in verification and validation. One way to apply formal methods is to utilize a formal design approach in PLC programming. However, for existing software that has to be optimized, changed, or ported to new systems .There is the need for an approach that can start from a given PLC program. Therefore, formalization of PLC programs is a topic of current research. The paper outlines a re-engineering approach based on the formalization of PLC programs. The transformation into a vendor independent format and the visualization of the structure of PLC programs is identified as an important intermediate step in this process. It is shown how XML and corresponding technologies can be used for the formalization and visualization of an existing PLC program.
