📌 IEC 61131-3 PROGRAMMING LANGUAGES IN CONTROL EXPERT
All Five Standard Languages
Control Expert supports all five IEC 61131-3 programming languages:
| Language | Best For |
|---|---|
| Ladder Diagram (LD) | Discrete control, interlocks, safety |
| Function Block Diagram (FBD) | Process control, analog signals |
| Structured Text (ST) | Complex calculations, algorithms |
| Sequential Function Chart (SFC) | Batch processes, sequences |
| Instruction List (IL) | Legacy support |
FBD: The Preferred Language for Process Control
FBD is particularly popular in Schneider's process automation applications. "EcoStruxure Control Expert incorporates advanced functions to facilitate the configuration of PLC modules". The FBD environment allows engineers to build complex control strategies using pre-built function blocks.
DFBs: Derived Function Blocks
"Creating and using DFBs" (Derived Function Blocks) is a key feature of Control Expert. DFBs allow you to:
Create reusable code blocks
Encapsulate complex logic
Build libraries for future projects
Standardize programming across teams
