基于CAN总线的PLC通信技术的研究
PLC Communication Technology Based on CAN Bus
摘要
Abstract
If CAN bus can convert with PPI protocol,then the intelligent nodes on the CAN bus can access S7-200 se-ries PLC,thus realizing the data communication between different networks.In this paper,the realization of the hardware design scheme of PPI protocol and CAN protocol is researched.The PPI interface circuit and CAN interface circuit are de-signed.The CAN application layer protocol is analyzed.The whole software structure and operation is analyzed.Finally,the conversion protocol is tested.关键词
