Programming

Standardization

The IEC 61131-3 standard defines a unified framework for PLC programming, ensuring consistency across languages and tools. It supports five languages—Ladder Diagram, Function Block Diagram, Structured Text, Instruction List, and Sequential Function Chart—each tailored for specific needs while remaining user-friendly.

• Ladder Diagram: Graphical logic representation, resembling electrical schematics.
• Function Block Diagram: Modular blocks for function-based programming.
• Structured Text: High-level, Pascal-like language for complex logic.
• Instruction List: Low-level, assembly-style coding.
• Sequential Function Chart: Flowchart-style program sequencing.

With built-in debugging, online editing, and version control, IEC 61131-3 simplifies development and maintenance, bridging the gap between novice and expert programmers.
