Abstract :
CAN bus is one of the most widely used field bus. In the light of the faults of PLC industrial network established by RS485, this paper presents a scheme for PLC accessing to the CAN bus network, which is based on the 32 bit MCU LPC2294. The author describes in detail the features of 32 bit ARM microcontroller, LPC2294 and CAN TJA1050T transceiver and gives the hardware structure and software design of PLC using as a CAN bus intelligent node. Combining with the actual use of the hardware, the author puts forward the anti interference measures.
