“…In this paper, we present the detailed design of a SCADA system using very few low-cost, low-power, and completely open source components. In our proposed SCADA solution, a locally installed Thinger.IO Server IoT Platform serves as the Master Terminal Unit where HMIs are created for data visualization and processing, and the versatile Sparkfun ESP32 Thing micro-controller serves as the Remote Terminal Unit for receiving and sending the sensor data from the Field Instrumentation Devices (sensors), while a local Wi-Fi Network provides the Communication Channel between the MTU and the RTU, resulting in a form of industrial network as implemented by the commercial SCADA vendors all over the world [3,9,11].…”

“…Unlike our work where a locally installed Thinger.IO IoT server is used, these authors have used the web-based Thinger.IO platform requiring the public internet for access which means that the resulting monitoring solutions are vulnerable to internet attacks. Security in a SCADA system is a serious issue as attacks on a SCADA system can compromise the critical process facilities being managed [4,9,25,26]. To ensure the security of a SCADA system, several techniques can be used.…”

“…It should be noted that the SCADA system solution presented in this paper is similar in functionalities to our previous open source IoT-based SCADA system [9], where we used a locally installed EMONCMS IoT server as the Master Terminal Unit, and Arduino Uno and Raspberry Pi as the RTUs to receive sensor data, with Node-RED flows, which used Ethernet for communication, serving as the Communication Channel between the MTU and the RTUs. However, as the components and the design and implementation methodologies used in both systems are totally different, the work presented here is not a continuation of our previous work but rather a different open source SCADA system solution meant to tackle the shortcomings in the available commercial SCADA systems, and the reviewed open source SCADA system solutions.…”

“…In this work, we propose a low-cost, open source SCADA system based on the most recent SCADA architecture, which is the Internet of Things [6,10,15]. Our proposed SCADA system uses reliable and commonly available components to achieve the four basic functions of a SCADA system which the available commercial SCADA systems also perform: Data acquisition, networked data communication, data presentation, and remote monitoring and supervisory control [1,9].…”

Supervisory Control and Data Acquisition (SCADA) is a technology for monitoring and controlling distributed processes. SCADA provides real-time data exchange between a control/monitoring centre and field devices connected to the distributed processes. A SCADA system performs these functions using its four basic elements: Field Instrumentation Devices (FIDs) such as sensors and actuators which are connected to the distributed process plants being managed, Remote Terminal Units (RTUs) such as single board computers for receiving, processing and sending the remote data from the field instrumentation devices, Master Terminal Units (MTUs) for handling data processing and human machine interactions, and lastly SCADA Communication Channels for connecting the RTUs to the MTUs, and for parsing the acquired data. Generally, there are two classes of SCADA hardware and software; Proprietary (Commercial) and Open Source. In this paper, we present the design and implementation of a low-cost, Open Source SCADA system by using Thinger.IO local server IoT platform as the MTU and ESP32 Thing micro-controller as the RTU. SCADA architectures have evolved over the years from monolithic (stand-alone) through distributed and networked architectures to the latest Internet of Things (IoT) architecture. The SCADA system proposed in this work is based on the Internet of Things SCADA architecture which incorporates web services with the conventional (traditional) SCADA for a more robust supervisory control and monitoring. It comprises of analog Current and Voltage Sensors, the low-power ESP32 Thing micro-controller, a Raspberry Pi micro-controller, and a local Wi-Fi Router. In its implementation, the current and voltage sensors acquire the desired data from the process plant, the ESP32 micro-controller receives, processes and sends the acquired sensor data via a Wi-Fi network to the Thinger.IO local server IoT platform for data storage, real-time monitoring and remote control. The Thinger.IO server is locally hosted by the Raspberry Pi micro-controller, while the Wi-Fi network which forms the SCADA communication channel is created using the Wi-Fi Router. In order to test the proposed SCADA system solution, the designed hardware was set up to remotely monitor the Photovoltaic (PV) voltage, current, and power, as well as the storage battery voltage of a 260 W, 12 V Solar PV System. Some of the created Human Machine Interfaces (HMIs) on Thinger.IO Server where an operator can remotely monitor the data in the cloud, as well as initiate supervisory control activities if the acquired data are not in the expected range, using both a computer connected to the network, and Thinger.IO Mobile Apps are presented in the paper.2 of 24 plants and industrial processes both locally and remotely. The system involves the examination, collection, and processing of data in real time, as well as data logging for historical purposes. The architectural design of a standard SCADA system starts with Remote Terminal Units (RTUs), and/or Programmable Logic Controllers...

“…Traditional and innovative SCADA technology enables plant users to collect data from one or more facilities, and limited control instructions are sometimes implemented. The new IoT paradigm opens up great potential services (e.g., PV coupled with Storage and new features in the context of plant digitalization and the Industry 4.0 context-for example, also using optical character recognition (OCR) systems) [18].…”

Photovoltaic (PV) plant monitoring and maintenance has become an often critical activity: the high efficiency requirements of the new European policy have often been in contrast with the many low-quality plants installed in several countries over the past few years. In actual industrial practices, heterogeneous information is produced, and they are often managed in a fragmented way. Several software tools have been developed for obtaining reliable and valuable information from the PV plant's raw data. With the aim of gathering and managing all these data in a more complex and integrated manner, an information managing system is proposed in this work-it is composed of a structured database, called the Photovoltaic Indexed Database, and a user interface, called the Digital Map, that allows for easy access and completion of the information present in the database. This information managment system and PV plant digitalization process is able to analyze and properly index the IR in the database, as well as the visual images obtained in photovoltaic plant monitoring.
