Development of an Industrial IoT Gateway Prototype

Abstract:

Nowadays, many industries have started to use different devices that allow the integration of process data through the internet to incorporate manufacturing into an Industry 4.0 scheme. In this regard, the present work involves the development of an IIoT Gateway to acquire data from industrial devices and through standard digital or analog inputs and outputs. The prototype provides bi-directional interaction with a remote station through Modbus RTU serial communications protocol under RS-485 interface. The implementation is based on an Arduino UNO board that incorporates an Ethernet module. The necessary functions are implemented in this board to establish communication and allow data management in higher layers under the MQTT protocol. A complementary monitoring interface was also developed using Node-RED. Several features were integrated within this interface, which includes an organized data displaying, real-time charts generation, and alarms that can be set and visualized based on the values of certain variables obtained through the developed gateway. The prototype and interface were tested to validate their operation and performance. The gateway is based on low-cost technologies and allows the integration of multiple protocols and industrial devices for possible future projects.
