Meaning
Shows the error status (logical OR of fa-
tal and non-fatal errors) of the target
node Controllers that are connected for
CIP communications 2, with the built-in
EtherNet/IP ports as the originator. The
array elements are valid only when the
corresponding Normal Target Node Infor-
mation is TRUE. The immediately pre-
ceding value is retained if this variable is
FALSE.
Array[x] is TRUE:
A fatal or non-fatal error occurred in the
target Controller with a target node ID of
x.
Array[x] is FALSE:
Other than the above.
Indicates that the connection for the Reg-
istered Target Node Information for CIP
communications 1 was not established or
that an error occurred in the target Con-
troller.
The array elements are valid only when
the Registered Target Node Information
is TRUE.
Array[x] is TRUE:
A connection was not normally establish-
ed with the target node for a target node
ID of x (the Registered Target Node Infor-
mation is TRUE and the Normal Target
Node Information is FALSE), or a con-
nection was established with the target
node but an error occurred in the target
Controller.
Array[x] is FALSE:
The target node is not registered for a
target node ID of x (the Registered Target
Node Information is FALSE), or a con-
nection was normally established with the
target node (the Registered Target Node
Information is TRUE and the Normal Tar-
get Node Information is TRUE).
An error occurred in the target Controller
(the Target PLC Error Information is
TRUE).
