Application of PLC in Power System Automation What is PLC? PLC (Programmable Logic Controller) is an electronic system designed for digital operation and automation control in industrial environments. It controls the start, stop, adjustment, and protection functions of various electrical devices through programming. The high stability and flexibility of PLCs have made them widely used … Read more
The project was completed two years ago, at a time when there wasn’t as much information about Fanuc robots available online. This project was completed through exploration, and I am writing this article based on my memory. If there are any inaccuracies, please take it lightly and consider this article as a reference idea.1. Control … Read more
In various scenarios, it is often necessary to monitor and control a large number of similar devices, each of which needs to display its own parameters and control options on the Human-Machine Interface (HMI). Designing sub-screens for each device on the HMI would greatly increase repetitive work and make the HMI program cumbersome. To simplify … Read more
The TextBox control in VB is widely used, and as learners of VB, it is essential for us to master it seriously. The TextBox control, also known as the text box control, is used to display information entered by the user and is a commonly used control for human-computer interaction. Below is a summary … Read more

Focusing on Automation Training for 14 YearsTechnical Training Network“ The programming soft components of the PLC are essentially memory units, each with a unique address. To facilitate different programming functions, the memory units are partitioned, resulting in various types of programming components. Soft components are devices within the PLC that have certain functions, composed of … Read more
Currently, PLCs are widely used centralized control devices in industrial production and automation control, replacing cumbersome relay cabinets, AC contactor cabinets, etc., and are gradually being popularized in production and control. Correct wiring of the PLC is a prerequisite for its functionality, and mastering the wiring of PLC input and output terminals is essential for … Read more
PLC Programming Algorithm (1): Digital Signals In PLC, there are three main types: digital signals, analog signals, and pulse signals. Understanding the relationship between these three will allow you to master PLCs proficiently. 1. Digital Signals are also known as logical signals, referring to two values: 0 or 1, ON or OFF. This is the … Read more
In many situations, there are a large number of similar devices that need to display and control device parameters through sub-screens in the HMI. If a sub-screen is drawn for each device in the HMI, it will lead to a lot of repetitive work and make the HMI program lengthy. Therefore, drawing a panel for … Read more
1. Design Concept PART 01 1. Use PLC to control a one-dimensional motion platform to achieve automatic forward and reverse operation of the motor as well as manual forward and reverse operation; 2. There are limit switches at both ends of the one-dimensional motion platform, defined as the forward limit and reverse limit respectively; 3. … Read more
