  • Abstract The CAN bus uses the message identifier as a priority by-bit arbitration mechanism, message can be delivered within a limited delay, suitable for use in real-time environment, an important basic layer protocol for the automation network. The Modbus protocol is an openly published and royalty-free application layer protocol, it is easy to deploy and maintain, simply and robust, high supportability, easy to be integrated in different devices, and has become a de facto standard communication protocol for HMI and PLC in SCADA system. The DNP3 protocol is robust, efficient, and interoperable, it provides multiplexing, data fragmentation, error checking, link control, and prioritization, suitable for large-scale distributed automation network architecture. This study proposes a distributed network architecture model that supports Modbus and DNP3, it is constructing based on CAN bus with low-cost and powerful error detection and correction capabilities. The design of Modbus and DNP3 protocol on the CAN bus can run Modbus commands on CAN bus and communicate between CAN and TCP/IP on Ethernet through the gateway, for achieving an automation area network which is reliable, easy to use and has well expandability to SCADA system.
