Web Server Support of Multiple Controllers Data Transfer in IoT Network

Abstract

In this paper a solution with a method for enabling data transfer among three remote industrial plants is represented. In particular, it examines the connectivity of three remote industrial plants within IoT network. Each plant is equipped with a WIFI controller along with corresponding hardware components including sensors and actuators. The sensors monitor conditions and signals when change occurs, while an actuator receives a signal and performs an action. Data that is generated by these sensors and actuators is transmitted via the controllers and consolidated onto a common single channel hosted in a designated WEB server. The setup enables the data that is collected from two controllers, designated as MASTER 1 and MASTER 2 stations, to be consolidated and accessed through a single controller referred to as SLAVE station. Within the SLAVE station, real- time visualization of the data is enabled and also, the results can be presented on SCADA screen.
