FBD Complexity Tool is a Java program used for measuring code complexity metrics of IEC 61131-3 Function Block Diagram programs. The tool supports FBD programs saved in the PLC Open TC6 XML schema.

Ladder logic continues to be the dominant language for programming PLCs, accounting for more than 81% of the global market, despite the availability of several other languages defined in the IEC 61131 ...

This paper attempts a journey right from configuring a PLC, writing application program to code generation along with run-time configurations and RTOS abstraction for embedding it into PLC hardware ...

The FBD diagram describes a function between input and output variables. A function is described as a network of elementary blocks. Input and output variables are connected to the blocks by link arcs.

Abstract: Industrial process engineering and PLC program development have traditionally favored Function Block Diagram (FBD) programming over classical imperative style programming like the object ...
