| Abstract: | A P87C591 based DeviceNet node interface was designed.P87C591 is chosen as CPU of the system,PCA82C250 as the transceiver for DeviceNet physical interface,and C51 language is used for programming the DeviceNet application layer communication protocol.A test experiment was carried out between IXXAT IPC-I320 DeviceNet communication interface card and this DeviceNet development node.The experimental result shows that the DeviceNet node interface fully meets the demand of DeviceNet specification. |
