The five IEC languages
The five graphical or textual languages available in Unity Pro are used for
programming Modicon M340, Premium and Quantum automation platforms.
The three graphical languages are:
b
Ladder (LD) language
b
Function Block Diagram (FBD)
b
Sequential Function Chart (SFC) or Grafcet
The two textual languages are:
b
Structured Text (ST)
b
Instruction List (IL)
For these five languages, you can use the standard set of instructions compliant with
IEC standard 61131-3 to create applications which can be transferred from one
platform to another. Unity Pro software also provides extensions to this standard set
of instructions. As they are specific to Modicon M340, Premium and Quantum PLCs,
these extensions support the development of more complex applications in order to
maximize the potential of the specific features of each of these platforms.
