I remember when I first joined the industry, I took over a project to upgrade an injection molding machine. The communication between the inverter and the PLC was always intermittent. After several days of troubleshooting, I discovered that the grounding was not done correctly, which caused interference. Today, I will share my experiences and techniques … Read more
Industrial Control Systems (ICS) are the core support of modern industrial fields, encompassing various types of control systems, among which the Supervisory Control and Data Acquisition (SCADA) system, Distributed Control System (DCS), Programmable Logic Controller (PLC), and Fieldbus Control System (FCS) are the most critical. These systems are not only widely used in power, water … Read more
With the rapid development of industrial technology, distributed control systems and fieldbus control systems have emerged one after another. In some industries, some people believe that FCS is developed from PLC, while others believe that FCS is developed from DCS. There is a close connection between FCS, PLC, and DCS, yet there are essential differences. … Read more
