_EIP1_CipErr CIP Communica-
tions1 Error
This is the error status variable for CIP
communications 1.
It represents the collective status of the
following error flags.
• _EIP1_IdentityErr (CIP Communica-
tions1 Identity Error)
• _EIP1_TDLinkCfgErr (CIP Communi-
cations1 T
ag Data Link Setting Error)
• _EIP1_TDLinkOpnErr (CIP Communi-
cations1 Tag Data Link Connection
Failed)
• _EIP1_TDLinkErr (CIP Communica-
tions1 Tag Data Link Communications
Error)
• _EIP1_TagAdrErr (CIP Communica-
tions1 Tag Name Resolution Error)
• _EIP1_MultiSwONErr (CIP Communi-
cations1 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 in-
formation on the meanings of
the error status bits at the end
of this appendix for details.
Note You can use this system-de-
fined variable only for NX-ser-
ies CPU Units.
