Development of a Programmable Logic Controller (PLC) Prototype Using Microcontrollers

Abstract

Process automation is essential for enhancing efficiency and competitiveness in modern industries; however, conventional systems such as traditional programmable logic controllers (PLCs) often involve high costs and complexity. This work proposes the design of a microcontroller-based PLC prototype using open-source software to reduce operational expenses. The prototype aims to provide an affordable automation solution for small and medium-sized enterprises seeking to implement automation without significant initial investments. The design focuses on key aspects such as hardware flexibility, adaptability to diverse applications, and cost-effectiveness. Preliminary results demonstrate the prototype's potential to improve productivity while maintaining economic feasibility. The study highlights the advantages of using open-source platforms and microcontroller technology as viable alternatives to traditional
