Correct Answer - Option 1 : Forward language 

Different Programming languages identified for PLC are:

  1. Ladder diagrams (LAD)
  2. Instruction list (IL)
  3. Sequential function charts (SFC)
  4. Structured text (ST)
  5. Function block diagrams or charts (FBD)
     

Ladder diagrams (LAD):

  • It is visual programming language is a PLC programming language called ladder logic or ladder diagram (LD).
  • It is a graphical PLC programming language that expresses binary logic operations with symbolic notation using ladder diagrams.
     

Instruction list (IL):

  • Instruction lists (or ILs) are one of the five PLC programming languages defined by the IEC 61131-3 standard.
  • ILs are not graphical programming languages. Instead, they most resemble assembly language programming.
  • It comes along with the Ladder Logic.
     

Sequential function chart (SFC):

  • It is a graphical programming language used for programmable logic controllers (PLCs).
  • The SFC standard is defined as, Preparation of function charts for control systems, and was based on GRAFCET (itself based on binary Petri nets).
     

Structured text (ST or STX):

  • It is one of the five languages supported by the IEC 61131-3 standard, designed for programmable logic controllers (PLCs).
  • It is a high-level language that is block-structured and syntactically resembles Pascal, on which it is based.
     

Function block diagrams or chart (FBD):

  • It widely used PLC programming language is the Function Block Diagram (FBD).
  • It is a simple and graphical way to program any functions together in a PLC program.
