Master CoDeSys OOP: Write Scalable PLC Code with Methods, Inheritance & Interfaces
What you'll learn
Implement core CoDeSys OOP features like Methods, Properties, and Access Specifiers to create well-encapsulated Function Blocks.
Design and utilize Inheritance (EXTENDS, ABSTRACT, SUPER) and Interfaces (IMPLEMENTS) to build flexible, reusable, and maintainable Function Block hierarchies.
Apply Polymorphism using Interface variables (IF 0) and runtime checks (__QUERY...) to create decoupled and adaptable automation logic.
Safely and effectively use Pointers (POINTER TO) and References (REFERENCE TO) in CoDeSys, understanding critical validity checks.
Apply key OOP Design Patterns (State, Command, Observer) to solve common automation software challenges.
Evaluate when and how to appropriately apply OOP principles and patterns in PLC projects, avoiding common pitfalls like over-engineering.
Requirements
Solid understanding of fundamental PLC programming concepts (variables, data types, logic, control flow).
Practical experience programming PLCs using Structured Text (ST) within the CoDeSys V3 development environment (IDE navigation, creating basic POUs, downloading, going online/debugging).
Experience creating and using standard Function Blocks (FBs) in CoDeSys.
No prior Object-Oriented Programming (OOP) knowledge is required - We will build from your existing PLC programming foundation.
