Prologue Using a computer for industrial process control is relatively easy to achieve now. We already have microcomputers and specialized industrial computers (Industrial Computer), and many devices and instruments in industrial production processes have also been “digitized”. They even have their own “embedded computers” and SOC components. They can operate independently and connect with each … Read more

This design guide discusses how to design RS-485 interface circuits. The necessity of balanced transmission line standards is discussed, along with an example of process control design. The article also covers line load, signal attenuation, failure protection, and current isolation under different headings. 1. Why Balanced Transmission Line Standards Are Needed This article focuses on … Read more
(1) Process Concept A process is a program that has been executed. It does not occupy disk space but consumes system memory, CPU resources, and each running process corresponds to its own virtual address space. (2) Concepts of Parallelism and Concurrency The CPU allocates a time slice to each process, and a process can run … Read more
Today, let’s talk about the differences between Modbus and TCP. These two protocols have both differences and close connections. Their combination not only enables remote network communication based on the Modbus/TCP/IP protocol but also promotes the use of Modbus in its corresponding fields. The Modbus protocol is mainly used in electrical automation and process control, … Read more
