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.

Functionally-Equivalent Formalization and Automated Model Checking of Function Block Diagrams Abstract: In the development and verification of safety-critical and safety-related Instrumentation and ...

The FlyWire connectome: neuronal wiring diagram of a complete fly brain Artificial intelligence and human expertise meet to generate a map of all the connections in the fly brain. The resource is ...

Ladder Diagram, based on the most common form of PLC programming language. Structured Text, similar to high-level information technology (IT) programming languages such as C or Pascal. Function Block ...

ISAGCA members and others from around the world contributed to the document, which encompasses advice covering the four primary programmable logic controller (PLC) programming languages: Ladder ...

In the previous articles in this series, we covered register functionality and documentation. This time, we dive deeper into block diagrams and more.

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.
