Development An Open-Source Industrial IoT Gateway

Bringing field devices and sensors to the cloud allows production plant to be connected, remotely monitored and controlled is a recently trending in industrial automation. The combination between SCADA and addition gateway, router with IoT protocols such as MQTT, CoAP... is a traditional solution in practice. This paper provides an alternative approach called Industrial IoT gateway and based on Linux tool-chain to build "unique" software and hardware solution for cloud connectivity. The set of Linux-based software including Docker and Node-RED allows generating, packaging and quickly deploying application that facilitates the data exchange from different industrial fieldbuses (Siemens S7, Modbus TCP and RTU) and IoT protocols (MQTT, HTTP). An industrial plant prototype is built and communication latency is also taken into consideration for evaluating the proof of concept.
