Function Block Diagram program (FBD program)
Function Block Diagram is a graphical programming language used to create a program by
arranging functions and function blocks on a network (circuit). Unlike Ladder Diagram
programs, contacts, coils and other ladder logic elements cannot be arranged in Function Block
Diagram programs.
In addition to the five programming languages compliant with IEC 61131-3, Continuous
Function Chart (CFC) and Page-Oriented CFC can also be used.

Instruction List program (IL program)
Instruction List is a programming language that creates assembler-like instructions sequentially
in text format. This language is suitable when you want to perform high-speed processing,
restrict the memory usage, and perform other similar operations.
In addition to the five programming languages compliant with IEC 61131-3, Continuous
Function Chart (CFC) and Page-Oriented CFC can also be used.
