Sequential Function Chart (SFC) is one of the PLC programming languages defined in the IEC-61131 standard. SFC has been increasingly used in practical applications because even small controllers can ...

SFC ("Sequential Function Chart"): derived from the GRAFCET language, this high-level language allows easy programming of all sequential processes; FBD ("Function Block Diagram"): this language lets ...

The differences among and preferences for Instruction List, Structured Text, Ladder Diagram, Function Block Diagram, and Sequential Function Chart PLC programming languages, as ...

Provide program structure But with SFC—which Jensen emphasizes is structure, not language—the end-user has a better alternative to get to a problem’s source. If, in the scenario above, which could be ...

A family of programming languages for programmable logic controllers (PLCs). Of the three graphical and two textual languages, ladder logic (see example below) was the first language and widely ...
