In the field of industrial automation, if you have paid attention to the methods of sensor signal transmission, you will definitely notice a strange phenomenon: Why do so many sensors choose to use 4-20mA for signal transmission? What is the secret behind this? Five Major Advantages There is a lot of noise interference in industrial … Read more
“The Path of an Excellent Engineer in Three Stages” 1. Basic Stage: Boto PLC technology. 2. Intermediate Stage: Boto and C# advanced language technology. 3. Advanced Stage: Standardized programming methods for PLCs. The Path to Standardization! An engineer asked me about the method of creating function blocks, which has probably puzzled him for a long … Read more
1. Overview of TCP Server Communication for PLC Sockets: In socket TCP server communication, the server first creates a socket, binds it to a specified IP address and port, and then listens for incoming connections. When a client initiates a connection request, the server establishes a reliable connection through a three-way handshake. The communication protocol … Read more
In non-standard automation projects, the delivery of equipment is just the beginning; the real test lies in subsequent maintenance. A standardized PLC program not only allows maintenance engineers to quickly get up to speed but also significantly reduces equipment failure rates and maintenance costs. Naming Conventions: Let the Program “Speak for Itself” The Golden Rules … Read more
Twenty years ago, MEMS inkjet print heads were widely used in printers, replacing traditional mechanical print heads, making companies like HP and Canon giants in the MEMS field.Ten years ago, with the rise of smartphones, MEMS microphones became widely used, replacing traditional electret microphones. Several MEMS companies in China, such as GoerTek, AAC Technologies, and … Read more
On September 3, the President of the American Society of Echocardiography, Dr. Cynthia C. Taub from the State University of New York Upstate Medical University, published a paper titled “Guidelines for the Standardization of Adult Echocardiography Reporting: Recommendations From the American Society of Echocardiography” in the Journal of the American Society of Echocardiography. This paper … Read more
Source: Semiconductor Industry Observer With the support of technical heavyweights, RISC-V is continuously growing, but it also brings challenges: encouraging CPU designers to maintain consistency and avoid the kind of fragmentation that occurred with MIPS and Android. In light of this, RISC-V International, which coordinates the development of the open-source instruction set architecture (ISA), has … Read more
1. Overview of PLC Socket TCP Client Communication: In socket TCP client communication, the client first calls a system function to create a TCP socket, then initiates a connection request to the server at a specified IP address and port. A reliable connection is established through a three-way handshake. The communication protocol can be customized … Read more
Why should M and T be avoided in PLC programs? The core logic of programming standardization. 1. Fundamental Flaws of Global Variables In PLC programming, global variables such as M (memory relay) and T (timer) are widely used but have inherent weaknesses: unclear ownership and a scope that covers the entire program. The M and … Read more
2025 is referred to as the “Year of Humanoid Robots” in the industry. The number of orders and market attention are rapidly rising, with the industry shifting from technical demonstrations of “running and jumping” to real-world validations of “working and delivering”. However, behind the prosperous facade, the industry is also undergoing a profound test. 1. … Read more
