Section 6-1
The following table shows the operation of each the bits when multiple con-
nections are used to communicate with a node, and the PLC status is speci-
fied in all of the connections.
Note
When the PLC status is not selected in the input (consume) tags, the PLC sta-
tus information (16-bit data) can be used as reception data.

Target Node PLC Operating Flag 
Information
Layout set to default settings:
Words n+2 to n+5
Layout set to user settings:
Words n+32 to n+47
Note Corresponds to the PLC sta-
tus’s PLC Operating Flag.
Each flag indicates the operating status of the 
corresponding target node PLC of connections 
in which the EtherNet/IP Unit is the originator. 
The flag corresponding to the target node’s 
target ID will be ON when the PLC Operating 
Flags for all connections with that target node 
indicate that the PLC is operating.
Each node address’s flag location (i.e., target 
ID) can be changed from the Network Configu-
rator.
The PLC status flags are enabled when the 
PLC status is included in the communications 
data for both the originator and target.
The data in this table is refreshed when neces-
sary.
Target Node PLC Error Flag Infor-
mation
Layout set to default settings:
Words n+6 to n+9
Layout set to user settings:
Words n+48 to n+63
Note Corresponds to the PLC sta-
tus’s PLC Error Flag.
Each flag indicates the error status (logical OR 
of non-fatal and fatal errors) of the correspond-
ing target node PLC of connections in which 
the EtherNet/IP Unit is the originator. The flag 
corresponding to the target node’s target ID 
will be ON if even one error is indicated in any 
of the connections with that target node.
Each node address’s flag location (i.e., target 
ID) can be changed from the Network Configu-
rator.
The PLC status flags are enabled when the 
PLC status is included in the communications 
data for both the originator and target.
The data in this table is refreshed when neces-
sary.
Normal Target Node Flag Table
Layout set to default settings:

Layout set to user settings:
Words n+16 to n+31
Note Does not correspond to the 
PLC status.
Each flag indicates the connection status of 
the corresponding target node PLC of connec-
tions in which the EtherNet/IP Unit is the origi-
nator. The flag corresponding to the target 
node’s target ID will be ON when connections 
are established for all connections with that 
target node indicate that the PLC is operating.
Each node address’s flag location (target ID) 
can be changed from the Network Configura-
tor.
