Abstract:
This article puts forward a method to implement the communication of control systems by CAN bus based on analyzing the disadvantages in distributed control system, and describes the advantage and characteristics in applying CAN bus. Aimed at the measurement and control system for a dynamo, this paper presents a brief introduction to CAN module of TMS320LF2407A, including the basic architecture and the software protocol in the data acquisition system for PowerCommand 1300.
