When wiring in industrial settings, the 9-pin interface of the PROFIBUS connector is a familiar sight for engineers—pins 3 and 8 are responsible for data transmission, which is common knowledge. But have you noticed that pins 2 and 7 are labeled for 24V power output? What are they used for? This easily overlooked detail is … Read more

Task Introduction In the production processes of enterprises, various intelligent production devices operate under the unified control and management of automated intelligent control units, forming an industrial-grade network working mode characterized by interconnection … Read more
Editor: Multi-line Source: Scarlett Evans, IoT World Today According to IoT World Today, two independent astronaut-assist robots played “hide and seek” on the International Space Station, marking a milestone in the field of robotics. The two robots, deployed by the German Aerospace Center (DLR) and the Japan Aerospace Exploration Agency (JAXA), communicated with each other … Read more
The IoT card, officially known as the IoT communication card, is a mobile communication access service provided by operators specifically for smart terminal devices. Unlike the mobile SIM cards we use daily, IoT cards use exclusive number ranges and are primarily sold in bulk to enterprise users, providing data transmission, remote control, and management services … Read more
In the field of industrial IoT and industrial control, it is inevitable to deal with Modbus devices, and debugging and managing these devices can often be complex and frustrating. OpenModScan, an open-source and free tool, addresses this pain point! If you need to quickly debug Modbus devices and easily parse data, this tool is your … Read more
According to industry experts such as PROCENTEC, applications based on RS-485 fieldbus technology (PROFIBUS®) are continuously growing, and industrial Ethernet (PROFINET) applications are also rapidly increasing. In 2018, a total of 61 million PROFIBUS fieldbus nodes were installed globally, with a 7% year-on-year growth in PROFIBUS process automation (PA) devices. The installation base for PROFINET … Read more
Someone is usingthe STM32H563 development productand has enabledDMA mode forSPI communication. They discovered an issue where, when theSPI data width is configured to16 bits or32 bits, using theSTM32 HAL library’sSPI DMA API start function results in no data transmission. However, if theSPI data width is configured to8 bits, the transmission works normally. What could be … Read more
Overview:The I2C communication interface is one of the most commonly used MCU peripherals in our daily applications. Initially, before MCUs had hardware I2C, I2C communication was accomplished by simulating I2C timing through GPIO ports. Later, as MCUs began to include I2C peripheral interfaces, the use of hardware I2C became commonplace. More importantly, this not only … Read more
Introduction Overview From deep space exploration to intelligent driving, FPGAs are driving system transformation When a satellite traverses layers of atmosphere and enters orbit, you may rarely think about the “programmable logic chip” hidden in its heart—FPGA. In the aerospace field, FPGAs (Field-Programmable Gate Arrays) are widely used for: ▪ Onboard data processing: Real-time processing … Read more
Click on the blue text above to intuitively learn about machinery and subscribe to us for long-term updates. I have previously worked on microcontroller and Modbus RTU serial communication for the following 20 types of PLCs. Here, I share the mapping of these PLC input, output, and register components to their corresponding Modbus address. Mitsubishi … Read more
