_EIP_CipErr CIP Communications
Error
This is the error status variable for CIP
communications.
NX-series CPU Units: Represents the col-
lective status of the following error flags.
•
_EIP1_IdentityErr (CIP Communications1
Identity Error)
•
_EIP1_TDLinkCfgErr (CIP Communica-
tions1 Tag Data Link Setting Error)
•
_EIP1_TDLinkOpnErr (CIP Communica-
tions1 Tag Data Link Connection Failed)
•
_EIP1_TDLinkErr (CIP Communications1
Tag Data Link Communications Error)
•
_EIP1_TagAdrErr (CIP Communications1
Tag Name Resolution Error)
•
_EIP1_MultiSwONErr (CIP Communica-
tions1 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 Set-
ting Error)
• _EIP_TDLinkOpnErr (Tag Data Link
Connection Failed)
• _EIP_TDLinkErr (Tag Data Link Com-
munications Error)
• _EIP_TagAdrErr (Tag Name Resolution
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 information on the
meanings of the error status bits at
the end of this appendix for details.
