Words n+16 to n+19 show the registration status of the target nodes that are
connected with the EtherNet/IP Unit as the originator.
These words show the status of nodes 0 to 63 only. If it is necessary to show
the status of nodes higher than node 63, select “user settings” as the layout
pattern. For details, refer to 4-4 User Settings Area.
Words n+20 to n+23 show the connection status of the target nodes that are
connected with the EtherNet/IP Unit as the originator. With revision 2 or
higher, the flag turns ON after all data for multiple connections for individual
target devices is refreshed in the CPU Unit. With revision 1, each flag immedi-
ately turns ON when all connections are established.
These words show the status of nodes 0 to 63 only. If it is necessary to show
the status of nodes higher than node 63, select “user settings” as the layout
pattern. For details, refer to 4-4 User Settings Area.
Word n+24 shows the status of FINS/TCP connections. For details, refer to
SECTION 8 FINS Communications.
