Function block diagram is another graphical PLC programming language ... with high complexity control loops, debugging will be an issue. I always prefer ladder logic. Easy to use.

Ladder logic ... for programming PLCs, accounting for more than 81% of the global market, despite the availability of several other languages defined in the IEC 61131-3 standard. New research from ...

This paper proposes a formal modeling and verification approach for programming function block diagrams. Function block diagrams are formalized in a logic specification system. We consider the ...

This class explains how function block diagram programming is used to program PLCs. It examines the basic rules that are used to construct an FBD program, including Boolean logic functions. It then ...

a standard industrial PLC using ladder-logic programming, and a Raspberry Pi 3 Model B programmed in Python under the Raspbian OS (based on Linux OS). Both hardware platforms use the same sensors and ...
