A-3-6 EtherNet/IP Function Module, Category Name: _EIP
Functional Classification: EtherNet/IP Communications Status
Variable name Meaning Function Data type
Range of
values
Reference
_EIP_EtnOnlineSta Online TRUE: The built-in EtherNet/IP port’s com-
munications can be used. (The link is ON
and IP address is defined. Also, there are
no errors.)
FALSE: The built-in EtherNet/IP port’s com-
munications is disabled due to an error in
initial processing, restart processing, or link
OFF status.
BOOL TRUE or
FALSE

_EIP_TDLinkRunSta Tag Data Link
Communications
Status
TRUE: At least one connection is in normal
operation.
FALSE: Other than the above.
BOOL TRUE or
FALSE
page A-78
_EIP_TDLinkAllRunSta All Tag Data Link
Communications
Status
TRUE: Tag data links are communicating in
all connections as the originator.
FALSE: An error occurred in at least one
connection.
BOOL TRUE or
FALSE

_EIP_RegTargetSta [255] Registered
Target Node
Information
This variable gives a list of nodes for which
built-in EtherNet/IP connections are regis-
tered.
This variable is valid only when the built-in
EtherNet/IP port is the originator.
Array[x] is TRUE: The connection to the
node with a target node ID of x is regis-
tered.
Array[x] is FALSE: The connection to the
node with a target node ID of x is not regis-
tered.
ARRAY
[0..255] OF
BOOL
TRUE or
FALSE

_EIP_EstbTargetSta [255] Normal Target
Node
Information
This variable gives a list of nodes that have
normally established built-in EtherNet/IP
connections.
Array[x] is TRUE: The connection to the
node with a target node ID of x was estab-
lished normally.
Array[x] is FALSE: The connection to the
node with a target node ID of x was not
established, or an error occurred.
ARRAY
[0..255] OF
BOOL
TRUE or
FALSE

_EIP_TargetPLCModeSta
[255]
Target PLC Oper-
ating Mode
This variable shows the operating status of
the target node Controllers that are con-
nected with the built-in EtherNet/IP port as
the originator.
The array elements are valid only when the
corresponding Normal Target Node Infor-
mation is TRUE. If the corresponding Nor-
mal Target Node Information is FALSE, the
Target Node Controller Operating Informa-
tion indicates the previous operating status.
Array[x] is TRUE: This is the operating state
of the target Controller with a node address
of x.
Array[x] is FALSE: Other than the above.
ARRAY
[0..255] OF
BOOL
TRUE or
FALSE
