![]() ![]() Not every SCADA system is greatly optimized. SCADA systems are used in energy, manufacturing, power, recycling, transportation, oil, and gas, as well as many other industries. Thanks to the versatile capabilities of SCADA systems, they can be used in both simple and complex installations. This further leads to the faster decision-making process and smarter use of time. The reason they’re being used is to maintain efficiency and accelerate the data distribution. Where is SCADA Used?Īs we mentioned earlier, SCADA systems are mostly used in factories and industrial organizations in both private and public sectors. This data can be checked via an HMI, which we’ll talk about later. If there’s an error somewhere in the process, it notifies the operator who can then pause the production process and check the data from the SCADA system. The sheer power of SCADA software allows us to process, distribute, and display the required data, thus making it easier for employees to analyze it and come up with solutions if needed. A PLC is essentially a microcomputer that directly communicates with a plethora of objects such as end devices, sensors, or numerous factory machines.Ī PLC, however, is directly hooked to the factory machine, while the RTU is used remotely, as its name implies. As such, the SCADA architecture consists of two basic parts – an RTU (Remote Terminal Unit) and a PLC (Programmable Logic Controller). These systems help save some time, they increase efficiency, they process data faster and with accuracy, and they allow for smooth communication between various parts of the system. In the modern time, there isn’t a serious organization that doesn’t take advantage of SCADA systems. ![]() Monitoring, acquiring, and processing real-time data.Interaction with sensors, pumps, motors, and valves through an HMI (Human-Machine Interface) software.Control of various processes from a remote location or locally.As we said earlier, it’s a system that has both software and hardware elements and is usually used for a couple of things: SCADA didn’t get its name by luck, it is actually an abbreviation that stands for Supervisory Control and Data Acquisition. We suggest that you grab a cup of coffee– it’s going to be a long read! ![]() Furthermore, we’ll discuss how they work together in a seamless system that controls different functions. In this article, we’ll talk about each of them and explain their functions. Since the SCADA system and an HMI can complete more or less the same functions, it’s crucial that you know the difference between these two. But, an HMI is also a system that works in conjunction with a PLC. A PLC is a hardware-based device, SCADA is a system that works in conjunction with the PLC. When it comes to the process automation and advanced system design, PLCs, SCADA, and HMIs play crucial roles.
