How Can IoT Take SCADA Systems to the Next Level?

The growth and acceptance of IoT technology in businesses would redefine a smart and intelligent system that does its job automatically. The presence of IoT would complement SCADA by widening the opportunities and allowing better functioning. With the help of predictable analysis, a data-driven approach, preventative maintenance of the equipment, detailed and organized report generation, and a customizable and personalized user dashboard, IoT-enabled SCADA would reach the new heights businesses have longed for.

With the increasing number of interconnected devices and steadfast growth in connectivity, the data has also potentially increased. To handle such massive data and keep it organized in numerous ways, IoT has to come into action sooner or later. With the inclusion of the Internet of Things as a brand-new concept in industries, performing analytical tasks and automated processing would come into play to render better services. This also provides benefits to managers in simplified information sharing and improved transparency.

It has been almost 40 years since SCADA systems have helped various industries to monitor and manage processes and applications. It has further boosted operational efficiencies and reduced overall costs. But with the advancement in technologies like the advent of IoT, it can be made better along with the needed improvements in equipment efficiency. With SCADA being an end-to-end supervisory system, acquiring data through remote terminal units (RTUs) connected to sensors, IoT is also an end-to-end system that uses advanced sensors to gather data from the assets for smooth functioning. However, with the installation of IoT-powered solutions and transformational attributes of sensor devices, gateways, and user-oriented dashboards, it is high time for industrialists to switch to IoT solutions. The answer can be installed in the existing SCADA system and offers quality services to the owners.

How does a SCADA system benefit from the integration of IoT technology?

The Internet of Things (IoT) is a disruptive technology that utilizes sensors, gateways, and interactive dashboards to improve business productivity across all areas. Unlike the current industrial SCADA system, which is limited to the factory floor and only displays data from within the plant, IoT can significantly enhance data accessibility and operability for various operations in different industries. Integrating IoT technology with existing SCADA systems can equip businesses with remarkable features like scalability, interoperability, and enhanced security for overall industrial processing. Furthermore, IoT can work alongside the SCADA system, transforming the entire SCADA landscape. To get started, it’s essential to identify the right IoT platform that offers a variety of adapters and connectors to integrate with the SCADA system. Here are eight significant benefits of implementing the Internet of Things into a SCADA system.

Overall Equipment Effectiveness (OEE)

The measurement of Overall Equipment Effectiveness (OEE) is a crucial metric for evaluating equipment availability, quality, and performance, whether a single machine or an entire business process. For the past 40 years, SCADA has been widely used in industries to monitor utility networks and industrial operations, providing detailed information on asset performance that enables managers to make informed decisions. However, the integration of IoT in SCADA significantly improves equipment effectiveness by applying real-time monitoring controls and advanced methods for maintenance controls like automatic data extraction, secured data transfer, and idle time collection. This utilization of IoT technology for OEE benefits production in industries and improves how managers retrieve and respond to equipment information.

Machine-to-machine Communication

The Internet of Things (IoT) focuses on machine-to-machine communication, allowing industrial equipment to interconnect via sensors, gateways, and other advanced technologies. By integrating IoT with SCADA systems, machine-to-machine communication can significantly improve, revolutionizing how industries operate. Incorporating IoT into existing SCADA systems enables managers to maintain real-time records of industrial processes more efficiently. Additionally, IoT technology offers quick accessibility through smart gadget connectivity, displaying the relevant details of the preferred device for the specific user. This facilitates efficient plant management and enables on-the-spot decision-making.

Data Acquisition

Integrating an IoT solution with a SCADA system can significantly enhance the data collection process in industries that rely on SCADA. While a SCADA system enables remote human interaction with industrial processes, IoT technology focuses on machine-to-machine communication. As SCADA systems continue to evolve, they will likely transition into IoT systems, providing a more intelligent and well-integrated platform. Therefore, one of the significant benefits of integrating IoT with SCADA is improved data acquisition, which allows for a better understanding and extraction of data. By utilizing the Internet of Things capabilities, data acquired can generate production and utility reports within an industry.


In data-driven production, security is a critical aspect that requires a well-informed infrastructure to manage effectively. Traditional SCADA systems lack systematic security measures, which can be significantly improved by integrating IoT-based solutions such as remote monitoring, anomaly detection, and secured data transfer. This enables server and application protection for the entire process across the data center, reducing the risk of data breaches. Additionally, managers can keep a live track of plant functioning and relevant details through an IoT SCADA system. By utilizing an IoT SCADA system, businesses can add value by ensuring well-monitored assets, secured networks, and assessed risks for better decision-making.

Remote Management and Monitoring

Open SCADA platforms are typically compatible with most OEMs and communicate well with PLCs from any OEM, reducing the likelihood of integration issues. This allows consumers or industrialists to easily customize the entire system, making an IoT SCADA a completely custom-built SCADA system. However, due to increased data capturing, asset owners now demand the integration of predictive algorithms, optimized asset health conditions, and cost savings. Therefore, utilizing IoT solutions for industrial SCADA systems proves efficient regarding plant management and keen monitoring.
