Chapter One: Differences Between FCS and DCS Traditional Method: A one-to-one I/O wiring method is used to connect field devices with 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 … Read more
First, fill in the transfer function of the device to be controlled, then determine the parameters for PID control, followed by setting the simulation time and sampling interval. Next, use the anti-integral saturation calculation method to determine the integral result of the PID, and then use the PID output to control the forward function, observing … Read more
Introduction The Six Core Data Types in PLC Programming That Are “Essential for Life” In the vast field of PLC programming and control, data types serve as the foundation that supports the stable operation and precise control of the entire system. For PLC engineers, mastering and applying various data types is an essential skill for … Read more
In industrial wastewater treatment and municipal sewage systems, the stable operation of sewage pumps directly determines the efficiency of wastewater treatment and environmental safety. Traditional manual control or relay control systems have issues such as response delays, frequent failures, and high energy consumption, making it difficult to meet the precise control requirements of modern wastewater … Read more
PLC Programmable Logic Controller Programmable Logic Controller (PLC) is a digital electronic device with a microprocessor used for automation control, functioning as a digital logic controller that can load control instructions into memory for storage and execution at any time. The programmable controller is modularly composed of an internal CPU, instruction and data memory, input/output … Read more
đź“ť Basic Concepts PLC stands for Programmable Logic Controller, which is a rugged computer used for automating processes.DCS, or Distributed Control System, is similar to PLC; it is also a rugged computer controller, but DCS includes multiple autonomous controllers distributed throughout the system, also used for automating processes. 🔍 Traditional Differences Initially, PLCs were mainly … Read more
In mechanical design, sensors are key components for achieving automation, intelligence, and precise control. Below are the top ten types of sensors commonly used in mechanical design and their application scenarios: 1. Magnetic Switch Function: Detects the position of the cylinder piston and provides feedback on the piston movement stroke. Application: Used in pneumatic control … Read more
First, fill in the transfer function of the device to be controlled, then determine the PID function. Next, use the unit feedback closed-loop transfer function formula to calculate the closed-loop function. Based on the ITAE optimal function, accurately determine the PID coefficients, and then use a pre-filter to cancel the zeros of the closed-loop transfer … Read more
01 Every time a device malfunctions, the first reaction from the client is: Is there a problem with the PLC program? When I say, “The program is fine,” the look they give me makes it seem like they want to stick two words on my forehead: Excuse Maker. Come on, the program is not the … Read more
Friends in the industrial control industry may often come across a term—PLC, but those outside the industry may not be familiar with it. Today, let’s take a look at what a PLC is. 1. One-sentence definitionPLC (Programmable Logic Controller) is an “industrial computer” designed specifically for industrial scenarios. It achieves automated control of machines, production … Read more
