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, […]

Safety Instrumented Systems (SIS) are critical components in many industrial settings. While safety certifications are essential, they alone do not define a system as an SIS. There are two key criteria to determine whether a system qualifies as an SIS: technical standards and engineering standards. Technical Standards: The system must comply with IEC61511, which provides

Introduction to PID Control PID (Proportional-Integral-Derivative) control is one of the most widely used and effective control algorithms in engineering. Its popularity stems from its ability to address fundamental control system requirements: stability, responsiveness, and accuracy. Despite the emergence of modern control methods, PID remains at the core of most automation systems. By tuning PID

1. Objective The purpose of this guideline is to ensure the safe and efficient operation of Uninterruptible Power Supply (UPS) systems, reduce equipment downtime, extend service life, and prevent power interruptions from causing operational or data losses. This document provides a comprehensive framework for the installation, usage, and maintenance of UPS systems. 2. Scope This

NPN and PNP sensors are widely used in industrial automation for detecting objects, positions, or other parameters. However, situations may arise where the output type of a sensor (NPN or PNP) does not match the PLC input requirements. This guide will explain how to convert an NPN sensor to behave like a PNP sensor, and

In modern industrial automation, robust communication protocols serve as the cornerstone of efficient system operations. With advancements in technology, industrial fieldbus protocols have evolved to facilitate faster, more stable, and intelligent data exchange between devices. This article delves into three widely adopted industrial communication protocols—Modbus, PROFIBUS, and Foundation Fieldbus. We will explore their various variants,

Introduction In the field of process control, discrepancies between words and actions are prevalent. These inconsistencies are often linked to the failure to integrate knowledge with execution. Knowledge and action are two sides of the same coin in problem-solving: knowledge without application is futile, and action without understanding is reckless. However, the issue of incongruence

Calculating the capacity of an Uninterruptible Power Supply (UPS) involves multiple considerations, including load power, backup time, efficiency, and load characteristics. This guide provides a detailed breakdown to help you select the right UPS for your needs. Step 1: Determine the Total Load Power Start by calculating the total power requirements of all connected devices.

Distillation column control revolves around maintaining material balance, operational stability, and product quality. Material and energy balances, as well as preventing liquid leakage and flooding, are essential considerations in any control strategy. 1. Importance of Product Purity The quality indicators of a distillation column typically include the purity of either the top or bottom product.

Introduction EtherCAT (Ethernet for Control Automation Technology) is a high-performance, real-time industrial Ethernet communication protocol specifically designed for data transmission in automation control systems. Introduced by Beckhoff Automation in Germany in 2003, EtherCAT has rapidly become one of the most widely adopted fieldbus technologies in industrial automation due to its exceptional performance and scalability.
