IoT based robust electrical energy monitoring system with Programmable Logic Controller

摘要

This paper develops an energy monitoring system with IoT integration. The platform used is based in a programmable logic controller (PLC) s7-1200 connected to a distributed power monitoring module through profinet interface. PLC is a robust and reliable solution for distributed power monitoring and enables IoT integration by using the embedded webserver functionality. In Spite of their excellent webserver capabilities, data management and human to machine interface (HMI) are limited. For this reason, a single board computer (SBC) is used in order to enhance their capabilities, providing data base management and improved data visualization. In this work, the practical aspects of both hardware and software are discussed. Results obtained by the platform are compared with a power quality analyzer.
