Industrial Automation and Controls refer to systems that enable fully or semi-automatic control of industrial processes. These systems integrate hardware, software, and network technologies to optimize production efficiency, product quality, and operational safety. Their importance in modern manufacturing includes reducing human errors, enhancing energy efficiency, and enabling Industry 4.0 capabilities through data-driven decision-making.
