Remake and set the routing tables
correctly, referring to System Settings
and Project Properties in the CX-
Designer's Online Help.
When the routing tables are not being
used, delete the routing tables.
Send a FINS command to the Control-
ler Link Interface Unit to read status,
correct the data where the error has
occurred, and reset the Board. If the
error occurs again, replace the
Controller Link Interface Unit.
Turn ON the terminating resistance at
the nodes at both ends of the network
and turn it OFF at all other nodes.
Check the cable connections and re-
connect correctly.
Either reset the maximum node ad-
dress using Controller Link Support
Software or reset the node address to
below the maximum.
Ensure that 2 or more nodes exist
within the Network.
Set the polling node using the CX-
Server.
Reset the baud rate for the Controller
Link in the CX-Designer's Communica-
tion Setting. For details on setting the
baud rate, refer to System Settings
and Project Properties in the CX-
Designer's Online Help.
