PROFINET Controller on Cloud

PROFINET (Process Field Network) is an industrial Ethernet standard widely used for real-time data communication in automation systems, with over 60 million active nodes as of 2024. It facilitates fast and reliable cyclic data transmission, enabling real-time monitoring and control between devices such as programmable logic controllers (PLCs), sensors, and actuators. Traditionally, controllers and devices needed to operate within close physical proximity to ensure successful IO data exchange. However, advancements in network technology now allow PROFINET IO data to be transmitted over VPN connections with acceptable latency. This development enables real-time data to be redirected from factory-level devices to cloud systems, overcoming hardware limitations, enabling data storage and analysis, and supporting complex algorithms for more flexible and efficient production. This study investigates the feasibility and benefits of using a PROFINET controller deployed on a cloud virtual machine and communicating over VPN technology, with a focus on the efficiency and communication characteristics between the controller and its network.
