Basics of Structured Text (ST) Programming | Examples & Applications

Overview

This video introduces Structured Text (ST) programming, one of the standard programming languages used in PLC systems according to IEC 61131-3.

Structured Text is a high-level, text-based programming language similar to languages like Pascal, making it suitable for complex calculations, algorithms, and advanced control logic.

The video explains the basic syntax, control structures such as IF statements and loops, and how ST is used in real industrial automation applications.
