The entire system must undergo strict debugging of all functions before being put into operation until it meets the requirements and is confirmed by … Read more
Special Training Course on Simulation and Design of Distillation Towers Online – Problem-Solving Ideas for Organic Synthesis in Pharmaceutical and Chemical Engineering Special Training Course DCS (Distributed Control System), also known as a distributed control system, is a type of computer control system that is developed and evolved from centralized control systems.PLC (Programmable Logic Controller). … Read more
This is a typical block diagram of a PLC control system: 1. Used for Switch Control The PLC has a strong capability for controlling switch quantities. The number of controlled input and output points can range from a few to hundreds, thousands, or even tens of thousands. Because it can be networked, the number of … Read more
1. What Is PLC? The International Electrotechnical Commission (IEC) defines PLC as: A programmable logic controller is an electronic system that performs digital operations and is designed for applications in industrial environments. It uses programmable memory to store instructions for executing logic operations, sequential control, timing, counting, and arithmetic operations, and controls various types of … Read more
Search on WeChat Jicheng Training If you’ve had any experience with PLC programming, you’ve probably heard terms like self-locking, interlocking, and mutual locking. These are typical fundamental programming steps in PLC programming that we must master. Below, I will share several of the most classic small programs. 1. Self-Locking (Start-Stop Control) Self-locking requires a normally … Read more
1. Used for Discrete Control The ability of PLC to control discrete signals is very strong. The number of input and output points can range from a few dozen to several hundred, even thousands or tens of thousands. Because it can be networked, the number of points is almost unlimited, and it can control any … Read more
The basic working method of a PLC is to sequentially execute the user program, executing one instruction per clock cycle. There are generally two types of execution for the user program: cyclic scanning and timed scanning. The scanning process is divided into three stages: input sampling stage, program execution stage, and output refresh stage, as … Read more
Today, I will share with you the content about PLC, giving you a simple introduction to PLC. I will briefly introduce the following five points. 1. First, let’s talk about what a control system and a controller are. Whether in the industrial field or in real life, such as air conditioners, humidifiers, refrigerators, elevators, or … Read more
Search on WeChat Technical Training Did you know that any complex engineering application consists of several basic programming steps? Therefore, we must master the basic programming steps and some typical basic control designs. Today’s article introduces the most basic controls of the PLC control system, including initialization control, fault control, output prohibition control upon power … Read more
Before understanding the PLC control cabinet, we need to grasp a few requirements. 01 Wiring according to the diagram is the highest principle. First, before wiring, you must carefully read the drawings and fully understand the designer’s intentions, rather than relying on personal so-called rich experience. If there are unclear or contradictory points, you should … Read more
