1. Overview of APL Two-Wire Ethernet Technology Definition and Principle APL (Advanced Physical Layer) is an Ethernet-based physical layer technology specifically designed for the process automation industry. It uses only two wires for both power supply and data communication, enabling safe and reliable operation even in hazardous areas. APL employs advanced modulation and encoding techniques, […]

In industrial process control, two types of control strategies dominate real-world applications: PID (Proportional-Integral-Derivative) control and MPC (Model Predictive Control). Despite the rapid development of modern control theory, these two methods continue to prevail in manufacturing plants worldwide. But why? 🔍 1. Process Control Is Not Just About Algorithms—It’s an Engineering Art Successful implementation of

In the realm of industrial automation, the need for seamless communication between field devices and centralized control systems is more critical than ever. While RS-485 continues to dominate field-level communication due to its reliability and cost-effectiveness, Ethernet-based networks have become the standard for modern industrial control and data acquisition systems. Bridging this gap is the

Relays are essential components in electrical circuits, often used for switching and control applications.
