Variable Description
_EIP_TargetPLCModeSta[255]
*1
(Target
PLC Operating Mode)
(Corresponds to the Controller Operating
Flag in the Controller status.)
This variable shows the operating status of the target node Control-
ler that is connected with the built-in EtherNet/IP port as the origina-
tor
.
The information in this area is valid only when the corresponding
Normal Target Node Information is TRUE. If the value is FALSE, the
Target Node Controller Operating Information indicates the previous
operating status.
Array[x] is TRUE: The target Controller with a node address of x
is in operating status.
Array[x] is FALSE: Other than the above.
_EIP_TargetNodeErr[255]
*2
(T
arget Node
Error Information)
(Corresponds to the Controller Error Flag
in the Controller status.)
This variable indicates that the connection for Registered Target
Node Information is not established or that an error has occurred in
the target the Controller
.
The array elements are valid only when the Registered Target Node
Information is TRUE.
Array[x] is TRUE: The Registered Target Node Information for a
node address of x is TRUE, and the Normal
T
arget Node Information is FALSE or the Target
PLC Error Information is TRUE.
Array[x] is FALSE: When the Registered Target Node Information
for a node address of x is F
ALSE, or when the
Registered Target Node Information is TRUE,
the Normal Target Node Information is TRUE,
and the Target PLC Error Information is FALSE.
_EIP_EstbTargetSta[255]
*3
(Normal T
ar-
get Node Information)
(This status is not included in the Control-
ler status.)
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 node ad-
dress of x is established normally
.
Array[x] is FALSE: A connection is not established yet, or an error
has occurred.
*1. This is a system-defined variable for NJ-series CPU Units.
For NX701 and NX102 CPU Units, the variable varies depending on the built-in EtherNet/IP port, as shown
below
.
Built-in EtherNet/IP port 1: _EIP1_TargetPLCModeSta
Built-in EtherNet/IP port 2: _EIP2_TargetPLCModeSta
For NX1P2 CPU Units, the variable is as below.
Built-in EtherNet/IP port 1: _EIP1_TargetPLCModeSta
*2. This is a system-defined variable for NJ-series CPU Units.
For NX701 and NX102 CPU Units, the variable varies depending on the built-in EtherNet/IP port, as shown
below.
Built-in EtherNet/IP port 1: _EIP1_TargetNodeErr
Built-in EtherNet/IP port 2: _EIP2_TargetNodeErr
For NX1P2 CPU Units, the variable is as below.
Built-in EtherNet/IP port 1: _EIP1_TargetNodeErr
*3. This is a system-defined variable for NJ-series CPU Units.
For NX701 and NX102 CPU Units, the variable varies depending on the built-in EtherNet/IP port, as shown
below
.
Built-in EtherNet/IP port 1: _EIP1_EstbTargetSta
Built-in EtherNet/IP port 2: _EIP2_EstbTargetSta
For NX1P2 CPU Units, the variable is as below.
Built-in EtherNet/IP port 1: _EIP1_EstbTargetSta
