In the development of industry, fieldbus plays a very important role, mainly applied in fields such as petroleum, chemical, electric power, medicine, metallurgy, manufacturing, transportation, national defense, aerospace, agriculture, and buildings. Today, I will introduce several types of fieldbus such as the Modbus communication protocol, PROFIBUS, FF, and CAN bus. Origin and Development of Modbus … Read more
Field of Application Smart Manufacturing Pain Points ยท Issue 1: Insufficient Bandwidth and Poor Anti-Interference of Traditional Fieldbus Technology With the intelligent development of the manufacturing industry and the exponential increase in the number of bus nodes, traditional fieldbus technologies (such as CAN, Profibus, etc.) can no longer meet the transmission requirements of massive data. … Read more
Bus control, as the name suggests, involves a single bus circuit connected to multiple devices. As shown in the figure below, all smoke exhaust outlets in the same smoke control zone can be controlled by a single bus control line. By pressing one button on the bus control panel, all smoke exhaust outlets can be … Read more
Introduction to In-Vehicle Networks As the complexity of electronic control systems increases, and the demand for communication capabilities among the electronic control units (ECUs) within vehicles grows, the use of point-to-point connections leads to an increase in wiring harnesses inside the vehicle. This creates significant challenges for reliability, safety, and quality in automotive design and … Read more
