Instruction List


Instruction List

IL (Instruction List) — язык программирования стандарта IEC61131-3. Предназначен для программирования промышленных контроллеров. По синтаксису напоминает ассемблер. Ориентирован на профессиональных программистов и разработчиков контроллеров и ПО для них. Является вместе с LD одним из самых распространённых при программировании ПЛК.

Пример: Линейное преобразование Y(x)=A*x+B

LD   x
MUL  A
ADD  B
ST   Y

Реализация языка Instruction List для контроллеров SIMATIC S7 производства SIEMENS носит наименование STL (Statement List) или AWL (Anweisungsliste).
