Application of PLC using MQTT protocol and AWS Services

This paper explores the integration of Programmable Logic Controllers (PLCs) with the Message Queuing Telemetry Transport (MQTT) protocol and Amazon Web Services (AWS) to enhance modern industrial automation. PLCs provide reliable control and automation in industrial environments, while MQTT facilitates lightweight, real-time communication over constrained networks. AWS IoT Core enables seamless data transfer, remote monitoring, and control of PLCs via cloud-based applications. Through this combination, industries can achieve improved operational efficiency, reduced downtime, and cost savings. A case study of Enel Green Power demonstrates how integrating these technologies significantly improved uptime, enhanced predictive maintenance capabilities, and enabled remote operations, showcasing the system’s scalability and resilience. The paper concludes by emphasizing the critical role this integration plays in advancing industrial automation and maintaining competitiveness in evolving markets.
