Abstract

The Industrial Internet of Thing (IIoT) mainly focuses on integrating and utilizing data completely within the production environment. To enhance IIoT the data from various devices and protocols are converted which help in providing a proper communication between the devices. There are still a lot of serial Modbus-based devices in use in industrial settings today. In modern industries serial Modbus-based communication is considered as one of the widely used one for maximum number of devices. Nearly all of the main manufacturers use MODBUS RTU in their new product as it is one of the mostly used industrial protocol for linking devices. The Modbus protocol has master-slave architecture where only device control and others follow. In other hand MQTT is a type of communication method which is well suited for IOT and they work on publish and subscribe model where devices send message (publish) and receive message (subscribe) based on specific topic. In this research, we used a low-cost Raspberry Pi single-board computer along with RS485 add-on board that contains the required ICs for data transfer and together they create a Modbus to MQTT gateway for Industrial IoT cloud applications. In addition, the system uses a Modbus RTU interface to over RS485 to provide efficient two-way communication between field devices and cloud applications.
