The Design of a Low Cost CANopen Slave Node Based on STC90C514RD

Abstract:

CANopen is a kind of higher layer protocol based on CAN, and it is widely used in industrial automation field, especially in distributed motion control systems. The paper presents an approach of realizing CANopen slave node. Microcontroller STC90C514RD is used as a core chip to design the control system; the design adopts CTM1050 as the CAN transceiver and uses SJA1000 as the CAN controller. And the system consists of a CANopen slave node, input module and output module. MicroCANopen, which is an open source protocol stack of CANopen, is transplanted to main controller so that the function of CANopen could be implemented. Moreover the experimental platform is built to test the design of the system. The results prove that the design is feasible and valid.
