Port Error
This is the error status variable for the com-
munications port.
It represents the following error flags.
• _EIP_MacAdrErr (MAC Address Error)
• _EIP_LanHwErr (Communications Control-
ler Error)
• _EIP_EtnCfgErr (Basic Ethernet Setting
Error)
• _EIP_IPAdrCfgErr (TCP/IP Basic Setting
Error)
• _EIP_IPAdrDupErr (IP Address Duplication
Error)
• _EIP_BootpErr (BOOTP Server Error)
• _EIP_IPRTblErr (TCP/IP Advanced Setting
Error)
Note If a Link OFF or Built-in EtherNet/IP
Processing Error occurs, it is recorded
in the event log and then the corre-
sponding bit turns ON. Refer to infor-
mation on the meanings of the error
