【Abstract】 With the high development of network technology, Ethernet communication technology got a very quickly develop speed in the industrial control area. It has penetrated into the network bottom of industrial automation system, and competed with the fieldbua technology. In this paper a kind of method with Ethernet that realized the communication of control system was discussed. And it realized the interconnected communication successfully between CPU24x series PLC of HOLLYSYS Company and S7-300/400 series PLC of SIEMENS Company.更多还原
