In the realm of industrial automation and process control, safety is paramount, especially when dealing with critical systems where human lives and significant assets are at stake. Three key concepts related to functional safety often come up: SIL (Safety Integrity Level), SIS (Safety Instrumented System), and SIF (Safety Instrumented Function). These terms form the backbone […]

1. Function of Terminal Boxes in SIS Systems In the wiring process of Safety Instrumented Systems (SIS), terminal boxes are commonly used for connection and signal distribution. They play a crucial role in simplifying wiring structures and enhancing system flexibility, particularly in complex process automation systems. The primary functions of terminal boxes in SIS systems

1. Introduction In industrial process control, ensuring operational safety and stability under abnormal or limiting conditions is a crucial challenge. Traditional methods for handling such non-standard operating conditions typically include emergency shutdowns or manual intervention. However, these approaches are often reactive rather than proactive. Selective control systems represent a more advanced solution by proactively switching

In industrial process control, whether a solution is perceived as “simple” or “difficult” often depends not only on technical complexity but also on how well the underlying problem is understood. Based on our practical experience in chemical plants, here are insights into what makes a control strategy effective—or frustrating—and how engineering mindset, collaboration, and empathy

In the process industry, once a system is operating normally, there are rarely unsolvable problems—most challenges revolve around efficiency and optimization. These issues can be addressed through human expertise, more advanced equipment, or knowledge-driven automation. Every industrial system, no matter how well-designed, will always have room for improvement. Acknowledging existing problems is the first step

Introduction In the realm of industrial automation, the Modbus protocol is highly regarded for its simplicity and broad applicability. For engineers and technicians, understanding the size of a Modbus frame is not merely a theoretical pursuit but a critical consideration in practical applications. The frame size directly influences communication efficiency, system response times, and network

Introduction Industrial Control Systems (ICS) play a critical role in monitoring and controlling equipment and processes in various industrial environments. These systems are indispensable in industries such as manufacturing, energy, transportation, and infrastructure, ensuring efficiency, quality, and safety. The core of ICS involves technologies and components like Programmable Logic Controllers (PLC), Supervisory Control and Data

In the quest to improve process automation in industrial environments, one crucial but often overlooked starting point is a deep understanding of the problem itself. Before introducing advanced technologies, it is essential to recognize the foundational role of basic control principles. However, in practice, many automation initiatives quickly jump to buzzwords—advanced control, expert systems, or

Advanced Process Control (APC) is a critical technology in industrial automation, widely used to optimize and enhance the efficiency of complex, multi-variable processes. By employing predictive modeling, optimization algorithms, and advanced control strategies, APC surpasses traditional methods like Proportional-Integral-Derivative (PID) control in precision and effectiveness. Its primary goals include ensuring product consistency, minimizing energy consumption,

In the pursuit of higher levels of automation, many industrial plants are investing heavily in new equipment and instrumentation. These investments are often necessary, and they do bring measurable improvements. However, installing hardware is only the starting point. The true objective of automation is not simply to add more devices—it is to enhance plant safety,
