_EIP_EstbTargetSta
[255]
Normal Target Node
Information
NX-series CPU Units: Gives a list of
nodes that have normally established Eth-
erNet/IP connections for CIP communica-
tions 1.
Array[x] is TRUE:
The connection to the node with a target
node ID of x was established normally.
Array[x] is FALSE:
The connection to the node with a tar-
get node ID of x was not established, or
an error occurred.
NJ-series CPU Units: Gives a list of nodes
that have normally established Ether-
Net/IP connections.
Array[x] is TRUE:
The connection to the node with a target
node ID of x was established normally.
Array[x] is FALSE:
The connection to the node with a tar-
get node ID of x was not established, or
an error occurred.
