NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
When you use multiple connections to communicate with one specific node, the information in the Con-
troller status is stored in the following variables if the Controller status is specified in the input tags and
the output tags for all connections.
Additional Information
Even if you specify including the Controller status in the output (produce) tags, you do not neces-
sarily need to include it in the input (consume) tags. If you do not include the Controller status in
an input (consume) tag, the contents of the Controller status is not updated in the Target PLC
Operating Mode and Target PLC Error Information variables, but it is sent in the input (consume)
tag. Therefore, you can use the Controller status data that was received in the input (consume)
tag as receive data.
Controller status Variable name Description of operation
Controller Operating Flag Target PLC Operating
Mode
• NX701 CPU Unit:
_EIP1_TargetPLC-
ModeSta (for built-in Eth-
erNet/IP port 1), or
_EIP2_TargetPLC-
ModeSta (for built-in Eth-
erNet/IP port 2)
• NX1P2 CPU Unit:
_EIP1_TargetPLC-
ModeSta (for built-in Eth-
erNet/IP port 1)
• NJ-series CPU Unit:
EIP_TargetPLCModeSta
This flag shows the operation information of the Controller at the
target node.
When the Built-in EtherNet/IP Port Is the Originator of the Con-
nection
The array element that corresponds to the target ID at the target
is TRUE when all information for all connections of the relevant
target node is shows operating status. You can change the target
ID of the IP address from the Network Configurator. This status
information is enabled when the Controller status is included in
the communications data in both the originator and target node.
This variable is updated when necessary.
Controller Error Flag Target PLC Error Informa-
tion
• NX701 CPU Unit:
_EIP1_TargetPLCErr (for
built-in EtherNet/IP port
1), or _EIP2_Target-
PLCErr (for built-in Ether-
Net/IP port 2)
• NX1P2 CPU Unit:
_EIP1_TargetPLCErr (for
built-in EtherNet/IP port 1)
• NJ-series CPU Unit:
_EIP_TargetPLCErr
This variable shows the error status (logical OR of fatal and non-
fatal errors) of the target node Controllers.
When the Built-in EtherNet/IP Port Is the Originator of the Con-
nection
You can change the target ID of the IP address from the Network
Configurator. The Controller Error Flags are enabled when the
Controller status is included in the communications data for both
the originator and target. This variable is updated when neces-
sary.
