The field bus control system (FCS) will be the mainstream of automatic control system development in the new century, and 3BHE024577R0101 PPC907BE is the new generation of control system after DCS. Fieldbus is a necessity for the development of comprehensive automation, and intelligent instruments and meters have laid the foundation for the emergence of fieldbus.

CAN (Controller Area Network) is a type of fieldbus, first introduced by Bosch in Germany in the 1980s, mainly used for internal inspection of automobiles and data communication between control systems. The CAN bus communication protocol fully considers the industrial field environment, and 3BHE024577R0101 PPC907BE adopts the three layers of the ISO-OSI model, namely the physical layer, data layer, and application layer. The CAN bus specification has been formulated by the International Organization for Standardization as the international standard ISO11898, and has received support from several well-known semiconductor device manufacturers, launching various chip products that integrate the CAN protocol. The CAN bus has been widely used and is recognized as one of the most promising fieldbuses.

Function and Characteristics of 3BHE024577R0101 PPC907BE CAN Bus

The communication medium of CAN bus generally uses twisted pair cables, coaxial cables, or optical fibers, which can achieve the function of long-distance data transmission in strong electromagnetic interference environments. Its hardware cost is low, transmission reliability is high, and software overhead is small. It belongs to the bus type serial communication network and has characteristics different from other communication protocols.
