In practical control projects centered around PLCs, the vast majority of cases rely on the collaboration of touch screens or host computers. This is because we use PLCs for control, mainly to handle some analog quantities, which are the values we need to monitor, such as pressure, temperature, and flow on the equipment. These detected … Read more

Human-Machine Interface connects programmable logic controllers (PLC), variable frequency drives, DC speed controllers, instruments, and other industrial control devices, using a display screen to show information, and through input units (such as touch screens, keyboards, mice, etc.) to write working parameters or input operation commands, realizing digital devices that enable information interaction between humans and … Read more
Field of Application Smart Manufacturing Pain Points · 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
CAN, short for “Controller Area Network”, is one of the most widely used field buses internationally. Initially, CAN was designed for microcontroller communication in automotive environments, exchanging information between various electronic control units (ECUs) in vehicles, forming an automotive electronic control network. For example, the engine management system, transmission controller, instrument equipment, and electronic backbone … Read more
Compared to STM32, the STM8 series microcontrollers, although less well-known, hold a certain position in industrial control and embedded systems due to their efficient performance and rich peripheral interfaces, among which the I2C (Inter-Integrated Circuit) interface plays an important role. This article will analyze the characteristics of the STM8 I2C interface and explain its advantages … Read more
