Additional Information
Communications Status with Target Node
The communications status with the target node of an NY-series Controller is shown by the com-
bination of the values of four system-defined variables.
•
_EIP_RegTargetSta
(Registered Target Node Information)
•
_EIP_EstbTargetSta
(Normal Target Node Information)
•
_EIP_TargetPLCErr
(Target PLC Error Information)
•
_EIP_TargetNodeErr
(Target Node Error Information)
Functional Classification: EtherNet/IP Communications Switches
You can start and stop tag data links.
.ExecTime
NTP Last Operation
Time
NY-series Controller: No change from the
initial value.
DATE_AND_
TIME
Depends on
data type.
.ExecNormal
NTP Operation Result NY-series Controller: No change from the
initial value.
BOOL
TRUE or
FALSE
Value of
_EIP_RegTarget-
Sta

_EIP_EstbTar-
getSta
Value of
_EIP_Target-
PLCErr
Value of
_EIP_Target-
NodeErr
Communications status with target
node
TRUE
TRUE
FALSE
FALSE
A connection with the target node was
established normally and there is no error
in the target PLC.
TRUE
TRUE
A connection with the target node was
established but there is an error in the
target PLC.
FALSE
Disabled
TRUE
A connection with the target node was
not established normally.
FALSE
Disabled
Disabled
Disabled
The information is not valid because the
target node is not registered.

Switch
NY-series Controller: Change this variable
to TRUE to start tag data links for CIP
communications 1.
It automatically changes back to FALSE
after tag data link operation starts.
Note
Do not force this switch to change
to FALSE from the user program or
from the Sysmac Studio. It changes
to FALSE automatically.

munications Stop
Switch
NY-series Controller: Change this variable
to TRUE to stop tag data links for CIP
communications 1.
It automatically changes back to FALSE
after tag data link operation stops.
Note
Do not force this switch to change
