How Does a SCADA System Work?
A SCADA (Supervisory Control and Data Acquisition) system is a critical industrial control system. It monitors and controls industrial processes in real time. It combines hardware and software components that give operators centralized visibility and …
What is Redundancy in Industrial Automation?
Redundancy in industrial automation refers to the use of backup or standby systems. These systems automatically take control when the main system experiences a fault or failure. This approach ensures continuous operation and prevents expensive …
What is Human-Machine Interface?
The human-machine interface (HMI), is a key part of modern technology. It acts as a bridge between people and the automated systems they use. HMIs enable smooth communication between humans and machines. They help operators …
What is IoT in Engineering?
The Internet of Things (IoT) is a rapidly growing field. It has changed the landscape of engineering in many significant ways. IoT refers to a vast network of physical devices, often called “things,”. The latter …
What is a Variable Frequency Inverter?
A Variable Frequency Inverter (VFI), also called a Variable Frequency Drive (VFD), is a device that controls how fast an AC motor runs. It does this by changing the frequency and voltage of the electricity …
What is a DCS?
In modern industrial automation, systems have evolved to handle complex processes with high efficiency and reliability. Among the most advanced solutions is the Distributed Control System (DCS). It enables operators to manage, monitor, and control …
Types of Industrial Automation Systems
Industrial automation uses control systems, software, and machines to perform industrial processes with little human help. This technology has changed manufacturing and production by improving efficiency, safety, and product quality. Automation reduces human error, increases …
What is a PLC Input Module?
Programmable Logic Controllers (PLCs), are the heart of modern automation. They control machines, manage processes, and keep factories running smoothly. One of the most important parts of a PLC system is the input module. Without …
Differences between SCADA, HMI, and PLC
In industrial automation, SCADA, HMI, and PLC are fundamental concepts that engineers, technicians, and operators encounter on a daily basis. Even though these three terms are often mentioned together and sometimes mistakenly used interchangeably, they …
