Introduction In the first half of this year, we implemented significant improvements in the sulfuric acid plant’s DCS (Distributed Control System). By optimizing control processes, we reduced operational events and alarms by over 90%. While this achievement is exciting, what inspires us even more is the innovative problem-solving applied within the DCS to achieve this […]

In control theory, the PID (Proportional-Integral-Derivative) controller is often considered the simplest and most effective control algorithm. For systems with a strong, single-variable cause-and-effect relationship, PID is not only straightforward but also highly efficient. The tuning of PID parameters is an essential skill for control engineers, and it remains the foundational knowledge for designing control

Introduction In a certain workshop, a PLC (Programmable Logic Controller) device, which had been running stably for some time, started experiencing frequent output failures. This malfunction caused the control of solenoid valves to fail, leading to a complete halt of the production line. Initially, maintenance electricians struggled to address the issue, unable to find a

Even if you don’t have in-depth knowledge of PLCs, you can still perform initial troubleshooting and maintenance by following these steps. However, for more complex issues, it’s recommended to consult a professional technician. 1. Initial Inspection Power Supply Check: Ensure the PLC power supply is functioning correctly. Check if the power indicator light is on.

Safety Instrumented Systems (SIS) play a critical role in ensuring the safety and reliability of industrial processes, particularly in high-risk sectors such as oil and gas, chemical manufacturing, power generation, and nuclear energy. SIS is a crucial layer of protection that automatically intervenes when abnormal or hazardous conditions are detected, mitigating risks to people, equipment,
