Advanced TIA Portal Tutorial#2: Multi-Instance Function Blocks & UDTs in Siemens TIA Portal

In this tutorial, we dive into two powerful concepts in Siemens TIA Portal that are essential for structured and scalable PLC programming: Multi-Instance Function Blocks (FBs) and User Defined Data Types (UDTs). You will learn how to design reusable function blocks, organize data efficiently using UDTs, and implement multi-instance FBs to simplify complex automation projects. This approach helps reduce memory usage, improves code readability, and makes large PLC programs easier to maintain. 🔧 What you will learn: What Multi-Instance Function Blocks are and why they are used Understanding User Defined Data Types (UDTs) in TIA Portal How FB instances work in Siemens PLC programming Step-by-step implementation of multi-instance FBs with UDTs Practical example for real industrial automation application
