WeChat Search Skill Training When electrical workers use PLCs, they will encounter many communication protocols and communication interfaces. Do you understand the most basic PLC serial communication and basic communication interfaces? 01 What is Serial Communication? Serial communication is a very common device communication protocol on computers (do not confuse it with Universal Serial Bus … Read more
Here we introduce thetouch screen and PLC connection considerations. The article may be a bit complex, but with careful reading, it can be understood. Interface Types (1) Connect to the PLC port (RS-422) 9-pin D-sub, female. It can connect to the PLC via RS-422, or connect two or more GOT modules (except for F920GOT-K) through … Read more
When using PLCs, you will encounter many communication protocols and communication interfaces. 01 What Is Serial Communication? A serial port is a very common device communication protocol on computers (do not confuse it with Universal Serial Bus or USB). Most computers have two RS232-based serial ports. The serial port is also a common communication protocol … Read more
Serial Communication My Diary 2024 Is the most basic communication method faced by electrical engineers, with RS-232 being the simplest among them. Many beginners often struggle to understand the relationship and differences between UART and RS-232, RS-422, RS-485. This article will discuss these concepts to help clarify their relationships. If we compare serial communication to … Read more
Serial communication is one of the most basic communication methods faced by electronic engineers. Although it seems simple, many people are not clear about the subtle differences between UART, RS-232, RS-422, and RS-485. Hope this engineering note can help everyone sort out their relationships. Communication issues, like traffic issues, also have various situations such … Read more
This article introduces the basic concepts of the serial communication protocols RS-232, RS-422, and RS-485, including baud rate, data bits, stop bits, parity bits, and handshaking information. 1. What is Serial Port? The concept of serial communication is quite simple. Serial ports send and receive bytes one bit at a time. Although it is slower … Read more

01 【Common Ground】 RS-232, RS-422, and RS-485 all belong to UART, which stands for Universal Asynchronous Receiver/Transmitter. They can complete the communication process using only two signal lines (Rx and Tx); However, due to the different voltage levels used by each, when converting from UART to RS-232, RS-422, or RS-485, a chip such as SP3232E … Read more
