In the context of Industry 4.0, digitalization and remote process control have become key enablers for increasing efficiency and operational flexibility in industrial environments. This study presents the design and implementation of a web-based remote-control system for a centrifugal pump, integrating Internet of Things (IoT) principles with the PROFINET communication protocol. A web server was deployed within a local Ethernet network using Node-RED, providing a responsive graphical interface accessible from mobile and desktop devices. This platform enables real-time monitoring, configuration, and operation of an electric actuator via a variable frequency drive. Experimental results validated the system’s ability to remotely start and stop the pump, modify operational parameters, and monitor tank levels with minimal latency. The solution significantly reduced system setup times and improved response capabilities. Overall, the integration of modern web technologies and industrial communication protocols proved effective in enhancing automation processes, demonstrating the potential of IoT-based platforms in scalable and accessible industrial control applications.
