Download these Object Oriented Programming examples in Structured Text programming language, with exercises to get hands-on in the free Codesys HMI/PLC simulator. Even if you are not designing a system, but rather just troubleshooting or modify a PLC program that uses the OOP programming method, having a working knowledge of the Object Oriented Programming language will make the job much easier. The experience gained in this OOP tutorial will be invaluable to your career advancement. Instructor Rick will walk you through creating each of the OOP examples, and then making several modifications to each program to maximize the learning experience.

This OOP Tutorial is great for those who are tired of trying to watch videos with unclear narration to learn OOP. This OOP tutorial will show you step-by-step how to program a PLC using OOP with Codesys in simple, easy to understand, examples. In case you are still not sure if you need this Object Oriented Programming experience, maybe a little more About the Object Oriented programming language below will help.

 

About the Object Oriented programming language

 

OOP is a way to package computer code or PLC (Programmable Logic Controller) instructions into reusable blocks or "objects" that can be used multiple times in a program or in other programs. OOP is a way to add structure to a program and keep program sections separate from one another so that the program does not end up with "spaghetti code" where multiple instructions affecting multiple elements are all mixed up together. OOP is not a new programming language in-and-of-itself, but rather a way to package code to make programs more efficient, reusable, and modifiable. High-level computer languages like C and C++ have used OOP for years, and recently OOP has crept into the programming of PLCs and has been added to IEC-61131-3 OOP. 

 

OOP is not a specific programming language, it is a methodology. Another PLC Object Oriented Programming example is the one the PLC programming software uses itself. The learner from this course will be well familiar with dragging a timer instruction onto the output of a rung of logic. That timer instruction dragged is an object class, and the resulting copy on the rung is an instance(copy) of that class. It is encapsulation in object oriented programming.

 

Encapsulation is an Object Oriented Programming concept that creates an instance of an object (class) by combining together the data and functions (methods) that manipulate the data (properties), and that keep both safe from outside interference and misuse. Data encapsulation led to the OOP concept of data hiding.
