| Abstract: | Aiming at the point to point real-time communication demand of field bus communication in FPGA＋ ARM system architecture of small programmable controllers, this paper analyzes the characteristics of the PLC communication and designs the 11-bit Standard Identifier, which includes the priority of the destination node and node number, according to CAN acceptance filter features and functionality. And the paper also presents the acceptance filter driver development and design of the identifier format. Tests show the design can achieve point to point real-time CAN communication. |
