Variable name _EIP_PortErr
Meaning Communications Port Error Global/local Global
Function This is the error status variable for the communications port.
It represents the following error flags.
• _EIP_MacAdrErr (MAC Address Error)
•
_EIP_LanHwErr (Communications Controller 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 corre-
sponding bit turns ON. Refer to Meanings of Error Status Bits given later for the meaning of individual bits.
Data type WORD Range of values 16#0000 to 16#00F0
R/W access R Retained Not retained. Network Publish Published.

tions
You can access this variable from the user program with the following
instruction.
• GetEIPError
Variable name _EIP_CipErr
Meaning CIP Communications Error Global/local Global
Function This is the error status variable for CIP communications.
It represents the following error flags.
