_EIP1_PortErr Communications
Port1 Error
This is the error status variable for the
communications port.
It represents the collective status of the
following error flags.
•
_EIP1_MacAdrErr (Port1 MAC Address
Error)
•
_EIP1_LanHwErr (Port1 Communications
Controller Error)
•
_EIP1_EtnCfgErr (Port1 Basic Ethernet Set-
ting Error)
•
_EIP1_IPAdrCfgErr (Port1 IP Address Set-
ting Error)
•
_EIP1_IPAdrDupErr (Port1 IP Address
Duplication Error)
•
_EIP1_BootpErr (Port1 BOOTP Server
Error)
•
_EIP_DNSCfgErr (DNS Setting Error)
•
_EIP_DNSSrvErr (DNS Server Connection
Error)
•
_EIP_IPRTblErr (IP Route Table Error)
Note If a Link OFF Detected or Built-in
EtherNet/IP Processing Error
occurs, it is recorded in the event
log and then the corresponding bit
turns ON.
Refer to information on the mean-
ings of the error status bits at the
end of this appendix for details.
Note You can use this system-defined vari-
able only for NX-series CPU Units.

ings of the error status bits at the
end of this appendix for details.
Note You can use this system-defined vari-
able only for the NX701 CPU Units.
