Supervisory Control and Data Acquisition Approach in Node-RED: Application and Discussions

Abstract

The Internet of Things (IoT) represents the binder of two worlds, specifically the real one and the digital one: tangible objects become recognizable in the virtual world, having digital matches, thus creating a network that enables the connection in-between the components. With the contemporary evolution of this domain, interconnectivity has become a primary fraction of new research and development directions. The Industrial Internet of Things (IIoT) is a concept that covers the more industrial level of the physical and digital connection and stays behind the Industry 4.0 concept. Supervisory control and data acquisition (SCADA) applications are important in the industry, their core being very present as complex products of big companies, at high prices. The Node-RED environment quickly evolved as one of the most important perspectives in IIoT, able to replace, up to a certain level, classic SCADA applications, bringing benefits to the industry. In this paper, the main focus is to evidence this aspect and to develop an application that will demonstrate the functionality of the concept, making use of protocols such as Modbus TCP (Transmission Control Protocol) for interacting with industrial devices and Message Queuing Telemetry Transport (MQTT) to interact with higher-levels, which provides a publish-subscribe structuring and a low band-width usage. The application uses logging and archiving modules based on InfluxDB database and is conceived to achieve the visual supervisory structure as close as possible to well-known SCADA solutions. The presented work results prove the efficiency of the solution.

“…In addition, the used load is legacy equipment which does not support modern communication interfaces, so being able to manage such valuable equipment is an important advantage. In fact, IoT technologies must contribute to solve compatibility and interoperability issues with legacy devices [47,48].…”

Review of Industry 4.0 from the Perspective of Automation and Supervision Systems: Definitions, Architectures and Recent Trends

“…SCADA systems and IIoT share some characteristics, such as data acquisition, processing and visualization. However, they are not mutually exclusive; on the contrary, they are complementary technologies [99,117,119].…”

“…Thus, the fourth generation of SCADA systems emerges as an evolution in which IoT enhances rather than replaces SCADA systems [116]. In this sense, IoT expands the vision of SCADA systems [117], providing the ability to collect and transfer data through a multitude of different protocols [119]. The deployment and use of SCADA systems are facilitated by the IIoT due to its ability to connect devices and processes [106].…”

“…The main purpose of this research is to investigate and analyze the phenomena under investigation to achieve a more thorough understanding of its underlying components and consequences. The study's importance lies in its ability to enhance the existing body of knowledge in the field, as well as its potential to offer insights and guidance for future research efforts and practical applications [1]. The optimization of network performance is facilitated by enhanced node clustering in the context of the Internet of Things (IoT), provide a notable advantage.…”

“…Despite the multitude of connections and opportunities presented by the Internet of Things (IoT) for end users and industry insights across many application fields, there exists a discernible lack in the construction of an effective architecture and standardized technological framework. The lack of this element poses a barrier to the smooth incorporation of the physical and virtual domains within a cohesive structure [1]. Several significant concerns have been discovered as follows.…”
