Target Node PLC
Error Information
(EtherNet/IP Unit to
CPU Unit) (n + 6 to n +
9)
These words show the error status (logical OR of fatal and non-fatal errors) of
the target node PLCs that are connected with the EtherNet/IP Unit as the orig-
inator. This status information is enabled when the PLC status is included in
the communications data in both the originator and target node.
These words show the error status of nodes 0 to 63 only. If it is necessary to
show the error status of nodes higher than node 63, select “user settings” as
the layout pattern. For details, refer to 4-4 User Settings Area.
The flags are valid only when the corresponding Normal Target Node Flag is
ON. If the corresponding Normal Target Node Flag is OFF, the Target Node
PLC Error Flag indicates the previous error status.
