A Modular Industrial IoT Scheme to Monitor and Control Distribution in a Substation Model

IoT - based remote monitoring and controlling of the substation is proposed in this work. It is done by using a Flexy-205 IoT Gateway and remote access router. The substation automation plant model has different model divisions such as City, Urban, Rural 1, and Rural 2, which have circuit breakers and lights. This model is controlled with the help of Siemens S7-300 programmable logic controller. A ladder logic program has developed in Simatic Manager software. The Flexy-205 is an advanced internet data gateway that allows machine builders to access and collect data remotely for evaluation and analytical maintenance. The remote access and data collection from the substation plant using S7-300 PLC with Flexy-205 is done by using Ebuddy and ECatcher software. The Graphical User Interface for substation remote access is created using viewON software. The proposed method is successfully tested on the substation remotely.
