3 System-defined Variables Related to the Built-in EtherNet/IP Port
Variable name
_EIP_CipErr
Meaning
CIP Communications Error
Function
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 Communications1 Identity Error)
• _EIP1_TDLinkCfgErr (CIP Communications1 Tag Data Link Setting Error)
• _EIP1_TDLinkOpnErr (CIP Communications1 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 Communications1 Multiple Switches ON Error)
NJ-series CPU Units: Represents the collective 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 Communications Error)
