The instruction list (IL) is a programming language used in automation technology to program control systems such as PLCs (programmable logic controllers). It is one of the oldest and most widely used programming languages in this field and is used to create control programs that automate the sequences in industrial production processes.

IL consists of a list of commands and instructions arranged in a structured form. These instructions are executed by the controller in sequence to perform the desired tasks. Typical tasks that can be programmed with IL include switching actuators such as motors and valves on and off, monitoring sensors and processing input signals.

The IL syntax resembles a mixture of textual and graphical elements. It consists of instructions such as SET (set), RESET (reset), ADD (addition), SUB (subtraction), JMP (jump), CALL (call) and others. These instructions are arranged in a hierarchical structure to implement complex control logic.

The instruction list offers a high degree of flexibility and performance when programming control systems. It enables engineers and technicians to develop customized control programs tailored to the requirements of a specific application. In addition, the clear and structured syntax of the IL facilitates troubleshooting and maintenance of control programs.

Overall, the instruction list is an indispensable tool in automation technology that makes it possible to efficiently control and monitor complex industrial processes. It forms the basis for the implementation of Industry 4.0 applications and contributes to the optimization of production processes in numerous industries.
