Abstract
In the field of industrial automation, two commonly used systems for process control are PLC (Programmable Logic Controller) and DCS (Distributed Control System). This paper aims to provide a detailed comparison between these two technologies by examining differences in architecture, scalability, response speed, programming methods, cost, and industrial applications. The findings indicate that PLCs are better suited for fast, centralized control tasks, whereas DCS systems perform more effectively in complex, continuous processes that require extensive coordination. more
