Instruction list (IL) is one of the 5 languages

supported by the initial versions of IEC 61131-3 standard, and

subsequently deprecated in the third edition.

It is designed for programmable logic controllers (PLCs).
It is a low level language and resembles assembly.
All of the languages share IEC61131 Common Elements. The variables and function call are defined by the common elements so different languages can be used in the same program.

Слайд 3Syntax of the language

Each statement begins on a new

line and contains an operator and, depending on the type

of operation, one or more operands separated by commas.

The operand can be preceded by a label ending with a colon (:).

The comment must be the last item in the line. There may be empty lines between instructions.

This language is a typical assembler with a accumulator and label transitions.

The following operators and modifiers can be used in IL:


Modifiers:
C with JMP, CAL, RET: the instruction is

executed only when the result is TRUE.
N with JMPC, CALC, RETC: the instruction is executed when the accumulator result is FALSE.
N in other cases: negate on of the operand.
