_EIP_CipErr CIP Communica-
tions Error
This is the error status variable for CIP com-
munications.
It represents the following error flags.
•
_EIP_IdentityErr (Identity Error)
•
_EIP_TDLinkCfgErr (Tag Data Link Setting
Error)
• _EIP_TDLinkOpnErr (Tag Data Link Con-
nection Failed)
• _EIP_TDLinkErr (Tag Data Link Communi-
cations Error)
• _EIP_TagAdrErr (Tag Name Resolution
Error)
• _EIP_MultiSwONErr (Multiple Switches ON
Error)
Note If a Tag Resolution Error occurs, it is
recorded in the event log and this vari-
able changes to TRUE. Refer to
Mean-
ings of Error Status Bits given later for
the meaning of individual bits.
