PROFIBUS is defined by the German national standard DIN19245 and the European standard EN50170. In the industrial field, PROFIBUS has become a universal, open, and distinctly communicative fieldbus standard. PROFIBUS is a fieldbus technology used for data communication and control at the workshop level for factory automation, enabling a communication network from the field device … Read more
5. CAN Communication Protocol CAN stands for Controller Area Network, which was developed by the German company BOSCH, known for its automotive electronic products, and has ultimately become an international standard (ISO11519 and ISO11898). It is one of the most widely used field buses internationally. CAN is a multi-master asynchronous serial communication bus. Due to … Read more

Among the various solutions for medium to long-distance communication between MCUs, RS-485 is widely used in factory automation, industrial control, community monitoring, and water resources automatic reporting due to its simple hardware design, ease of control, and low cost. However, RS-485 bus still has defects in anti-interference, adaptability, and communication efficiency. Improper handling of some … Read more

CANopen is a high-level protocol based on the CAN (Controller Area Network) serial bus system and CAL (CAN Application Layer). CANopen assumes that connected devices have hardware with a CAN transceiver and a CAN controller that comply with the ISO 11898 standard. The CANopen communication protocol CiA DS-301 includes periodic and event-driven communication, which not … Read more
