发明名称 METHOD FOR CHECKING IP ADDRESS COLLISION OF ETHERNET COMMUNICATION MODULE OF PLC
摘要 A method for checking an IP address collision is provided. The method includes: transmitting an ARP (Access Resolution Protocol) request message by setting an IP address of the PLC Ethernet communication module as a destination; receiving an ARP reply message responding to the ARP request message; determining whether an MAC (Media Access Control) address included in the ARP reply message is identical to an MAC address of the PLC Ethernet communication module; and determining that an IP address collision occurs, when the MAC (Media Access Control) address included in the ARP reply message is not identical to the MAC address of the PLC Ethernet communication module.
