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. [ 1 ] It is designed for programmable logic controllers (PLCs).
The S5 product line was usually programmed with a PC based software programming tool called STEP 5. STEP 5 was used for programming, testing, and commissioning, and for documentation of programs for S5 PLCs. The original STEP 5 versions ran on the CP/M operating system. Later versions ran on MS-DOS, and then versions of Windows through Windows ...

There is usually limited support for arrays and loops, often resulting in duplication of code to express cases that in other languages would call for use of indexed variables. As microprocessors have become more powerful, notations such as sequential function charts and function block diagrams can replace ladder logic for some limited applications.
Standard IEC 61131 is divided into several parts: [3]. Part 1: General information. It is the introductory chapter; it contains definitions of terms that are used in the subsequent parts of the standard and outlines the main functional properties and characteristics of PLCs.
The CODESYS Professional Developer Edition offers the option to add components to the tool which are subject to licensing, e.g. integrated UML support, a connection to the version control systems Apache Subversion and Git, online runtime performance analysis ("Profiler"), static code analysis of the application code or script-based automated ...
The software system is modular. The functionalities of the COMOS platform support the digital transformation [5] of a plant via the object-oriented database and a special layer technology that permits joint and consistent work on data and documents. Object properties or attributes can be changed in data sheets and various entry masks.
