Choosing between a Programmable Logic Controller (PLC) and a Distributed Control System (DCS) requires a specific analysis based on the situation, as different applications have varying requirements for control systems. When communicating with clients, we can approach the discussion from the following aspects! PLC and DCSPLC 1. Development from switch control to sequential control, transport … Read more
Introduction As an industrial control computer, PLCs have a modular structure, flexible configuration, high processing speed, and precise data processing capabilities. PLCs also have good control capabilities for stepper motors, utilizing their high-speed pulse output function or motion control function to achieve control over stepper motors. For specific devices where both the distance and speed … Read more

Chapter One: Differences Between FCS and DCS Traditional Method: A one-to-one I/O wiring method connects field devices to controllers. Fieldbus Technology: All field devices are connected using a single cable. Detailed Comparison of FCS and DCS Chapter Two: Differences Between DCS and PLC Currently, there is no strict boundary between DCS and PLC. Most people … Read more
In the field of industrial automation, “SCADA” and “PLC” are two frequently mentioned terms, yet many people still struggle to distinguish between them. Some may ask: “Who is responsible for monitoring? Who is responsible for control?” Today, let us clarify this in a straightforward manner. What is SCADA? SCADA (Supervisory Control and Data Acquisition) is … Read more
When it comes to the work of electricians, the older generation relied on abacuses and notebooks. To calculate loads, they would simply draw a line with a pen; to change wiring, they would manually sketch a wiring diagram. Later, relays were strung together like beads on an abacus, where any movement would trigger a response, … Read more
Imagine an automated factory: conveyor belts operating precisely, robotic arms moving freely, production lines running 24/7… Who is giving the orders behind this orderly operation? Is it a group of engineers frantically operating computers in the background? No! The real conductor is a metal box called PLC. It is the “strongest brain” in the field … Read more
Click the blue text to follow us Introduction In modern welding workshops, fixtures are no longer cold steel giants. Beyond precise pneumatic and mechanical structures, they are endowed with perceptive “nerves” and “eyes.” These “eyes”—various sensors—monitor every subtle aspect of the production process in real-time, serving as the unsung heroes behind achieving high automation, high … Read more
