With the rapid advancements in automation technologies, many have begun questioning whether Human-Machine Interfaces (HMIs) will remain relevant in the future. While automation and artificial intelligence are reducing the need for human intervention, HMIs are still crucial for many reasons. This article explores the evolving role of HMIs in the automation industry and examines their […]

1. Introduction to STS (Static Transfer Switch) A Static Transfer Switch (STS) is an advanced electronic switch used in Uninterruptible Power Supply (UPS) systems to ensure seamless and reliable power transfer between two independent power sources. Built with semiconductor devices such as Silicon-Controlled Rectifiers (SCRs) or Insulated-Gate Bipolar Transistors (IGBTs), STS can switch power sources

Before performing a shutdown of a Distributed Control System (DCS), it is essential to conduct a thorough inspection to ensure a smooth and risk-free process. Below is a detailed checklist for pre-shutdown inspection: 1. Data Backup Purpose: To prevent data loss and ensure quick recovery in case of system failure after the shutdown. Verify that

PLC (Programmable Logic Controller) control cabinets are advanced automation solutions that combine compact design, reliable operation, and comprehensive functionality. These cabinets feature essential protections such as overload, short circuit, and phase loss protection. Their modularity allows them to scale with control requirements, supporting standalone automation or integration into distributed control systems (DCS) via industrial Ethernet

In modern automation systems, the transmission and processing of signals are core components of system design. Particularly for communication between devices and systems, the integration of signals, such as SDI (Serial Data Input) and SDO (Serial Data Output), into Distributed Control Systems (DCS) is a critical technical task. This article explores how SDI and SDO

The control of drum level in heat recovery boilers has often followed traditional guidelines, such as: The proportional control action for drum level should not be too aggressive due to the presence of false level indications. To address significant fluctuations in steam load, three-element drum level control is often considered the preferred method for conventional

Introduction In electrical control systems, two-wire and four-wire configurations are commonly used wiring methods. They differ significantly in terms of working principles, applicable scenarios, and advantages and disadvantages. This article provides an in-depth analysis of the basic principles, features, application scenarios, and pros and cons of these two wiring methods, offering readers a clearer understanding

Programmable Logic Controllers (PLCs) have been a cornerstone of industrial automation since their introduction in the 1970s. Designed as electronic systems capable of performing digital operations in industrial settings, PLCs have become essential in modern industrial control systems due to their reliability and efficiency. This article delves into the pivotal role PLCs play in the

Programmable Logic Controllers (PLCs) are the cornerstone of modern industrial automation systems. The choice of a PLC programming language has a significant impact on the efficiency, maintainability, and performance of these systems. With a variety of programming languages available, each with its own strengths and suitable applications, it is essential to understand their characteristics to

Introduction Industrial automation is a cornerstone of a company’s competitive advantage, directly influencing safety and efficiency. Among the critical aspects of automation management is the self-control utilization rate, which measures the degree to which automated systems are deployed effectively in production processes. While management tools such as inspections, rankings, and performance evaluations are commonly applied,
