Overview of Tag Data Links 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.
Name (allocated area) Contents
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.

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.

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)
