Variable Description
• EIP_Comm1Status.TargetNodeErr[255] (CIP Com-
munications1 T
arget Node Error Information)
• EIP_Comm2Status.TargetNodeErr[255] (CIP Com-
munications2 Target Node Error Information)
(Corresponds to the Controller Error Flag in the Con-
troller status.)
This variable indicates that the connection for Regis-
tered 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 Regis-
tered Target Node Information is TRUE.
Array[x] is TRUE: The Registered Target Node In-
formation for a node address of x
is TRUE, and the Normal Target
Node Information is F
ALSE or the
Target PLC Error Information is
TRUE.
Array[x] is FALSE: When the Registered Target
Node Information for a node ad-
dress of x is FALSE, or when the
Registered T
arget Node Informa-
tion is TRUE, the Normal Target
Node Information is TRUE, and
the Target PLC Error Information
is FALSE.
• EIP_Comm1Status.EstbTargetSta[255] (CIP Com-
munications1 Normal T
arget Node Information)
• EIP_Comm2Status.EstbTargetSta[255] (CIP Com-
munications2 Normal Target Node Information)
(This status is not included in the Controller status.)
This variable gives a list of nodes that have normally
established EtherNet/IP connections.
Array[x] is TRUE: The connection to the node with
a node address of x is establish-
ed normally.
Array[x] is F
ALSE: A connection is not established
yet, or an error has occurred.
