课程名称：PLC 编程 - 高级面向对象编程 (OOP) 课程概述：您是否厌倦了与复杂且难以维护和重用的PLC代码斗争？是否准备好超越基本功能块，发掘现代PLC编程的全部潜力？本综合课程将引导您掌握专门针对CoDeSys V3环境（IEC 61131-3）的高级面向对象编程（OOP）技术。此课程旨在为熟悉结构化文本（ST）和标准功能块的有经验的PLC程序员提供指导，弥合传统方法与强大的OOP原则之间的差距。 如果您是PLC编程新手，或需在进阶OOP之前打好结构化编程概念的基础，强烈建议您先学习其他课程：“PLC 编程 - 使用 CoDeSys 学习基础知识”以及“PLC 编程 - 结构化编程与设计模式”。 课程内容包括： 1. 理解OOP在自动化中的重要性，解决常见问题，并展示其在管理复杂性方面的优势。 2. 深入应用CoDeSys中的OOP特性，通过方法、属性和访问修饰符创建更清晰、更直观的代码。掌握THIS指针的关键作用。 3. 强化内存管理：自信使用指针（如POINTER TO, ADR, ^）和引用（如REFERENCE TO, REF=），学习其语法、应用及必要的安全检查（0，__ISVALIDREF）以确保PLC代码的可靠性。 4. 构建可重用的层次结构：探索继承（EXTENDS），基于公共代码创建专业功能块，学习覆盖方法，利用SUPER指针，以及使用抽象类定义健壮模板。 5. 实现真正的灵活性：发现接口（INTERFACE，IMPLEMENTS）以定义能力契约并解锁多态性，学习如何编写与多种对象统一交互的解耦代码，使用接口变量和运行时检查（__QUERY...）。 6. 应用实践知识：学习适用于自动化的OOP设计模式（状态模式、命令模式、观察者模式、适配工厂模式），掌握特定于OOP结构的调试技术，理解关键最佳实践，包括何时不使用OOP，以及如何使用包装器模式重构遗留代码。 课程通过与自动化场景（如驱动控制）相关的实际示例，并提供练习来巩固您的理解。为确保与提供的练习项目兼容，建议学生安装CoDeSys开发系统V3.5 SP19 Patch 5。 通过本课程结束时，您将不仅仅了解OOP，还能自信地设计、实施和维护复杂、可扩展、可重用且高度可维护的PLC应用程序，使用先进的OOP技术在CoDeSys V3中实现。今天就报课，提升您的PLC编程技能到一个新水平！
Tired of wrestling with complex PLC code that's hard to maintain and reuse? Ready to move beyond basic Function Blocks and unlock the full potential of modern PLC programming?This comprehensive course is your guide to mastering Advanced Object-Oriented Programming (OOP) techniques specifically within the CoDeSys V3 environment (IEC 61131-3). Designed for experienced PLC programmers familiar with Structured Text (ST) and standard Function Blocks, this course bridges the gap between traditional methods and powerful OOP principles.This course is designed for experienced PLC programmers comfortable with Structured Text (ST) and standard Function Blocks. If you are new to PLC programming or need a stronger foundation in structured programming concepts before tackling advanced OOP, I highly recommend checking out my other courses first: "PLC Programming - Learn the Basics with CoDeSys" for beginners, and "PLC Programming - Structured Programming and Design Patterns" for intermediate concepts.We'll start by understanding why OOP matters in automation, addressing common concerns and demonstrating its benefits for managing complexity. Then, we dive deep into the practical application of CoDeSys OOP features:Enhance your Function Blocks: Learn to create cleaner, more intuitive code using Methods, Properties, and control visibility with Access Specifiers. Understand the crucial role of the THIS pointer.Master Memory Management: Gain confidence using Pointers (POINTER TO, ADR, ^) and References (REFERENCE TO, REF=), learning their syntax, applications, and essential safety checks ( 0, __ISVALIDREF) vital for reliable PLC code.Build Reusable Hierarchies: Explore Inheritance (EXTENDS) to create specialized FBs based on common code. Learn to Override methods, leverage the SUPER pointer, and utilize ABSTRACT classes to define robust templates.Achieve True Flexibility: Discover Interfaces (INTERFACE, IMPLEMENTS) to define capability contracts and unlock Polymorphism. Learn how to write decoupled code that interacts with diverse objects uniformly using Interface Variables and runtime checks (__QUERY...).Apply Practical Knowledge: Learn OOP Design Patterns adapted for automation (State, Command, Observer, adapted Factory), master Debugging techniques specific to OOP structures in CoDeSys, and understand crucial Best Practices - including when not to use OOP and how to refactor legacy code using the Wrapper pattern.Throughout the course, we use practical examples rooted in automation scenarios (like controlling drives) and provide exercises to solidify your understanding.Throughout the course, we use practical examples rooted in automation scenarios (like controlling drives) and provide exercises to solidify your understanding. To ensure compatibility with the provided exercise projects, it is advised that students install CoDeSys Development System V3.5 SP19 Patch 5.By the end of this course, you won't just know about OOP; you'll be able to confidently design, implement, and maintain complex, scalable, reusable, and highly maintainable PLC applications using advanced OOP techniques in CoDeSys V3.Enroll today and elevate your PLC programming skills to the next level
