1. RS-232 RS-232-C is a serial physical interface standard established by the Electronic Industry Association (EIA) in the United States. RS stands for “Recommended Standard,” 232 is the identification number, and C indicates the revision number. Its full name is “Serial binary data exchange interface technology standard between Data Terminal Equipment (DTE) and Data Communication … Read more
Introduction: In the previous article (Architecture of LoRa IoT), we discussed the network structure of LoRaWAN. This article will focus on the end devices in the LoRaWAN network structure. There are generally four ways to develop end devices. 1. Module Pure RF module: Generally has an SPI interface and requires an external MCU, which eliminates … Read more
In the current field of industrial automation, EtherCAT (Ethernet for Control Automation Technology) has been widely used as a high-performance, real-time industrial Ethernet communication protocol. With its efficient data transmission capabilities, precise synchronization performance, and flexible topology, it has become an indispensable part of many automation systems. As the basic unit in the EtherCAT network, … Read more
In order to achieve information collection and command output over as large a range as possible, we need to distribute the IO through a fieldbus. How can this be achieved? The answer is to connect several IO couplers on the communication bus, which communicate data with controllers such as PLC. The PLC and other controllers … Read more

To build a stable and reliable Profibus-DP network, termination resistors can be considered a “small component with a big role”! Many engineers often overlook their importance, resulting in spending several days troubleshooting inexplicable communication failures, only to find out that it was the termination resistors causing the trouble. Today, we will analyze this seemingly simple … Read more
In a Profibus-DP network, the bus length is one of the key factors affecting system stability. As the bus length increases, signal attenuation, delay, and interference also increase, which changes the requirements for termination resistors. Today, we will discuss in detail how to correctly choose and install termination resistors for different lengths of Profibus-DP buses. … Read more
