Design and Implementation of Group2 only Slave Node Based on DeviceNet

Referred to the protocol specification of DeviceNet, the hardware structure was set up by analysis of the physical layer and data link layer. Then it emphasized the software implementation procedure of the communication between master and slave from the view of application layer. With the software and hardware design method, a group 2 only communication node based on DeviceNet was designed through the platform of CAN controller SJA1000. Finally both IXXAT Corporation’s DNSDT protocol analysis software and RockWell’s master device were used to test the slave node. And the experimental data is detailed to verify that this slave node can fully meet the requirements specification of DeviceNet.
