This article primarily focuses on formalisation and model checking of Function Block Diagram (FBD) algorithms. However, the presented methods can also be extended to other programming languages.

Functional programming, as the name implies, is about functions. While functions are part of just about every programming paradigm, including JavaScript, a functional programmer has unique ...

Functional programming with arrays Although JavaScript’s arrays are very capable out of the box, the functional paradigm improves the clarity and maintainability of array code.

The IDE itself supports programming ladder diagrams, functional block diagrams, and other programming systems covered under the IEC 61131-3 standard.

In the programmable logic controller programming tool software, the conversion from function block diagram to instruction list plays an important role. Aiming at the problems of the existing algorithm ...

PLC's are the standard platform for automation applications, and can they can be programmed in one or more of the 4 programming languages as defined by IEC116131-3: Instruction List, Ladder Diagram, ...

IEC-61131 languages In addition to ladder logic, the standard supports other programming methods that are compatible with each other. They include function block diagram; structured text; sequential ...

A function block diagram is a more intuitive depiction of the algorithms used by a PLC. Instruction list (IL) is a low-level language that represents sub-algorithms and functions in a simple list.
