_EIP_CipErr CIP Communications
Error
This is the error status variable for CIP
communications.
NX-series CPU Units: 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)
NJ-series CPU Units: Represents the col-
lective status of the following error flags.
• _EIP_IdentityErr (Identity Error)
• _EIP_TDLinkCfgErr (Tag Data Link
Setting Error)
• _EIP_TDLinkOpnErr (Tag Data Link
Connection Failed)
• _EIP_TDLinkErr (Tag Data Link Com-
munications Error)
• _EIP_TagAdrErr (Tag Name Resolu-
tion Error)
• _EIP_MultiSwOnErr (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.
