Programming languages

The ve IEC 61131-3 compliant languages

The ve graphical or textual languages available in Unity Pro are used for

programming Modicon M340, Modicon M580, 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 ve 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 specic to Modicon M340, Modicon M580, Premium and

Quantum PLCs, these extensions support the development of more complex

applications in order to maximize the potential of the specic features of each of

these platforms.

LL984 language

LL984 (Ladder Logic 984) language enables migration from legacy Modicon ranges.

It is used to program Modicon M340 and Quantum automation platforms.
