Study And Realization Of General Intelligent Interface Board Based On Devicenet

Based on the analysis of current situation and development trend of study about DeviceNet-based device, the basic contents of Field bus and CAN bus is introduced, the concept and characteristic of DeviceNet is explained, the likeness and difference between DeviceNet and CAN is analyzed, especially in the aspect of communication model, network topology and error control. The powerful application layer protocol of DeviceNet is summarized, which differs from Control Area Network. According to DeviceNet protocol specification, hardware and software of general intelligent interface board which based on DeviceNet is designed. Through debugging and running, realize the link and basic communication function between field intelligent device and DeviceNet. The anti-disturbance in the aspect of software and hardware in the system is analyzed.
