_EIP2_CipErr CIP Communica-
tions2 Error
This is the error status variable for CIP
communications 2.
It represents the collective status of the
following error flags.
•
_EIP2_IdentityErr (CIP Communications2
Identity Error)
•
_EIP2_TDLinkCfgErr (CIP Communica-
tions2 Tag Data Link Setting Error)
•
_EIP2_TDLinkOpnErr (CIP Communica-
tions2 Tag Data Link Connection Failed)
•
_EIP2_TDLinkErr (CIP Communications2
Tag Data Link Communications Error)
•
_EIP2_TagAdrErr (CIP Communications2
Tag Name Resolution Error)
•
_EIP2_MultiSwONErr (CIP Communica-
tions2 Multiple Switches ON Error)
Note If a Tag Name Resolution Error
occurs, it is recorded in the event
log and this variable changes to
TRUE. Refer to information on the
meanings 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.

_EIP_TcpAppErr TCP Application
Communications
Error
This is the error status variable for TCP appli-
cation communications.
It represents the collective status of the
following error flags.
•
_EIP_TcpAppCfgErr (TCP Application Set-
ting Error)
•
_EIP_NTPSrvErr (NTP Server Connection
Error)
Note Refer to information on the mean-
ings of the error status bits at the
end of this appendix for details.

_EIP_MacAdrErr MAC Address Error NX-series CPU Units: Indicates that an
error occurred when the MAC address
was read on the communications port 1 at
startup.
TRUE: Error
FALSE: Normal
NJ-series CPU Units: Indicates that an
error occurred when the MAC address
was read at startup.
TRUE: Error
FALSE: Normal
BOOL TRUE or
