CIP Communica-
tions1 Registered
Target Node Informa-
tion
Gives a list of nodes for which
EtherNet/IP connections are registered
for CIP communications 1.
This variable is valid only when the
EtherNet/IP port is the originator.
Array[x] is TRUE:
The connection to the node with a target
node ID of x is registered
.
Array[x] is FALSE:
The connection to the node with a target
node ID of x is not registered.

tus.TargetPLCMo-
deSta[255]
CIP Communica-
tions1 Target PLC
Operating Mode
Shows the operating status of the target
node Controllers that are connected for
CIP communications 1, with the Ether-
Net/IP port as the originator.
The array elements are valid only when
the corresponding Normal T
arget Node
Information is TRUE. If the corresponding
Normal Target Node Information is
FALSE, it indicates the previous operat-
ing 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.
