Checking with Instructions That Read Error Status
You can use instructions in the user program to check the error status of each function module. The fol-
lowing table gives the instruction that is used to get error information for the EtherNet/IP Function Mod-
ule.
Instruction
GetEIPError
For details on the instructions that get error status, refer to the NJ/NX-series Instructions Reference
Manual (Cat. No. W502).
Checking with System-defined Variables
You can use system-defined variables to check for errors in the EtherNet/IP Master Function Module.
 Error Status Variables
You can check for errors in each function module of the NJ/NX-series Controller with error status
variables. The following variables show the error status of the EtherNet/IP Function Module.
Variable name
_EIP_ErrSta
_EIP_PortErr
_EIP1_PortErr
_EIP2_PortErr
_EIP_CipErr
_EIP1_CipErr
_EIP2_CipErr
_EIP_TcpAppErr

Outline of function
The GetEIPError instruction gets the highest level status
(partial fault or minor fault) and highest level event code
of the current Controller errors in the EtherNet/IP Func-
tion Module.
Gives the collective error status of all error
status for the EtherNet/IP Error Function
Module.
Gives the collective error status of all error
status for the EtherNet/IP communications
port on an NJ-series CPU Unit.
For an NX-series CPU Unit, this variable
gives the same status as the Communica-
tions Port 1 Error variable and you can use it
instead of the Communications Port 1 Error
variable.
Gives the collective error status of all error
status for the EtherNet/IP communications
port 1 on an NX-series CPU Unit.
Gives the collective error status of all error
status for the EtherNet/IP communications
port 2 on an NX701 CPU Unit.
Gives the collective error status of all error
status for CIP communications on an NJ-
series CPU Unit.
For an NX-series CPU Unit, this variable
gives the same status as the CIP Communi-
cations 1 Error variable and you can use it
instead of the CIP Communications 1 Error
variable.
Gives the collective error status for CIP
communications 1 for an NX-series CPU
Unit.
Gives the collective error status for CIP
communications 2 for an NX701 CPU Unit.
Gives the collective error status for TCP
applications communications.
