Hydraulic Control System for Bending Machines 01 Abstract This thesis aims to design an efficient, stable, and precise hydraulic control system for bending machines. By analyzing the working principles and requirements of bending machines, combined with advanced hydraulic control technology, the design of the hydraulic servo control system for bending machines is realized. This design … Read more
Alright, my friend, I see you have directly posted your salary—18,000 Yuan per month. This figure is very realistic for someone who has worked as a PLC engineer for ten years; it can even be said to reflect the typical state of this industry: not starving, but also not getting rich; steady progress relies entirely … Read more
Background Data Block The backgroundDB block is associated withFB blocks. When creating a backgroundDB block, it is necessary to specify theFB block it belongs to, and thatFB block must already exist, as shown in Figure1. When calling anFB block, you can either assign it an already created backgroundDB block (for example, data block_1), or directly … Read more
Core Concept: From “Wiring Technician” to “System Architect” First, please change a core concept. An excellent PLC programmer is not just an “electrician” who follows wiring diagrams, but a “system architect” who oversees the entire project. They must ensure that every brick (bit logic) is placed correctly, and design the entire structure (automation system) with … Read more
Don’t be afraid of complex PID tuning and mismatched program logic in industrial temperature control debugging! Follow the actual program points step by step, and control will be easy to implement. Completely align with your program data blocks and logic, and achieve the entire process from signal conversion to PID adjustment and pump-valve coordination in … Read more
Search WeChatAutomation Knowledge Base Hello everyone, I am Lao Zhou, an electrician with over ten years of experience. Recently, many colleagues have messaged me, and the most common question is about learning PLC: “Lao Zhou, how do I learn PLC?” “Is there a quick way to get started?” “Are there any shortcuts?” Every time I … Read more
01 After working in this field for over a decade, what exhausts me the most is not the complex processes or tight deadlines, but rather the casual remark from some individuals: “Can you think of a way to write the program?” This statement seems sincere, but it is actually a curse that shifts the technical … Read more
In Huichuan PLC programming, variables often include arrays and structures. Today, I will share the usage of both. After reading, you will surely feel a sense of familiarity. Array Variables When defining custom variables in Huichuan PLC programming, arrays are frequently used, with the data type being ARRAY. First, open the variable table, enter a … Read more
How can you quickly improve your PLC programming skills? With 15 years of experience in the automation industry, I have the authority to speak on this.Thinking back to when I first encountered automation PLCs in 2010, my mind was blank; I couldn’t understand the client’s requirements, and I felt anxious when seeing projects, leading to … Read more
In the field of industrial automation, being able to write a PLC program that makes equipment operate is just the beginning. However, being able to write an excellent program that is stable, efficient, and easy to maintain is the key to distinguishing an ordinary electrician from a programming expert. So, what are the characteristics of … Read more
