Supervisory control and data acquisition (SCADA) systems have been the cornerstone for managing, monitoring, and automating industrial processes for decades. However, everything changes and moves to a combination of SCADA and IoT. In fact:
A modern SCADA system cannot help but incorporate IoT approaches. Still, it’s impossible to disregard local solutions like PLCs and RTUs, tried and tested in this field over the years.

Offering IoT product development services, we know what it takes to create custom SCADA software solutions. Our very own product, 2Smart Standalone, initially an automation platform, has evolved to complement the needs of SCADA systems perfectly.
Using 2Smart Standalone as an example, we’ll explore:

Before SCADA systems emerged, industrial processes relied on simple dials displaying pressure, temperature, utility meter data, and other equipment indicators. Controlling these required a physical presence — engineers constantly monitoring devices and manipulating wired control panels with switches and buttons.
Needless to say, ensuring 24/7 operation meant a dedicated team on-site.

Maintenance cost reduction was the driving force behind SCADA’s development. Early systems incorporated existing solutions like time relays, offering a taste of automation. However, this approach introduced new challenges during maintenance, replacement, and reconfiguration.

The rise of microprocessors in the 1950s was a turning point. These compact devices became the perfect solution for automation and monitoring in SCADA systems.
Architecturally, SCADA comprised a set of sensors and controls connected to factory equipment. The equipment was linked to PLCs or RTUs and further integrated into a single network. A server running specific software was connected to this network for data collection and analysis. The PLC or RTU performed automation logic. Physical human-machine interfaces (HMIs) were and are still being used for manual control.
Before integrating IoT in SCADA, these systems were proprietary and didn’t allow combining equipment from different manufacturers into one ecosystem. However, with the growth of the IT industry in the 2000s, they started implementing open protocols and approaches. This shift enabled industrial businesses to combine various hardware sets into cohesive SCADA systems.

Now, as technology advances, SCADA’s reliance on wired connections between system components is decreasing. More solutions for remote control and monitoring appear.

It’s at this point using the Internet of Things in a SCADA system becomes prevalent.
Using IoT in SCADA offers plenty of benefits for improving industrial processes. Let’s explore how this combination impacts your operations:
Overall equipment effectiveness, or OEE, shows how well your equipment is used compared to its full potential. Using IoT and SCADA lets you better understand equipment health, ultimately tackling performance bottlenecks and optimizing production efficiency.
Owing to the connectivity technologies in IoT, you combine all your devices and equipment into a single ecosystem. As a result, you get a seamless data exchange and next-level automation.
Traditional SCADA systems rely on a limited set of data points. IoT, instead, captures info from previously inaccessible areas. This makes process optimization and decision-making even easier.
IoT and SCADA integration enables real-time monitoring and management of your operations from anywhere. This is especially beneficial in situations that require quick response.
Combining SCADA and IoT lets you access additional security features. Those include advanced monitoring, access controls, intrusion detection, and threat detection software.
As your business needs evolve, so too can your SCADA system. Given the modular nature of IoT devices and platforms, Scaling IoT devices and platforms is a relatively simple process.
The Internet of Things cuts operational costs by improving efficiency, reducing energy consumption, and offering predictive maintenance. Wonder how much an IoT prototype will cost? Check out our recent article on IoT prototype cost estimation.
The IoT and SCADA combination lets you leverage predictive analysis for your equipment. You can study data from IoT sensors to tackle equipment failures before they occur.
WebbyLab’s product, 2Smart Standalone, can be used as a form of SCADA software.
Only after implementing 2Smart Standalone did we realize that this product could serve as excellent SCADA software. Though it requires specific modifications for this field, its flexible architecture makes it absolutely ready for this.

Here is how 2Smart Standalone can be used as SCADA in IoT:
3. The product is highly versatile and flexible in terms of connecting devices. These could be off-the-shelf devices using Modbus or KNX protocols, or any devices with communication interfaces like MQTT or REST API.
Thanks to the built-in bridge architecture, we can integrate with any device. This is currently a must-have task for SCADA systems to avoid limitations in equipment from one manufacturer.

6. The built-in automation feature enables the configuration of alerting scenarios and maintenance predictions, and, if necessary, automatic equipment control.
The potential benefits of using SCADA and the Internet of Things are highly promising. Still, there are several challenges to consider:
Using the SCADA system in IoT leads to the next level of industrial automation, monitoring, and control. Promising enhanced efficiency, improved decision-making, and optimized operations, you cannot but adopt IoT solutions.

Leveraging SCADA protocols in IoT lets devices seamlessly communicate with SCADA systems. Ultimately, this ensures reliable and efficient data exchange for uninterrupted industrial processes.
SCADA systems primarily focus on monitoring and controlling industrial processes. IoT, on the other hand, is responsible for connecting numerous devices, ensuring data exchange, and improving performance.
It’s hardly possible. Instead, SCADA systems and IoT are expected to work together. SCADA solutions will continue to provide the core functionality for monitoring and control, while IoT’s interconnectedness will facilitate the whole process.
SCADA systems combine hardware and software technologies like RTUs, PLCs, HMIs, communication networks, and specific data collection platforms.
