The node address
is larger than the
maximum node
address set in the
network parame-
ters.
Either change the
maximum node
address setting
with the Controller
Link Support Soft-
ware (Ver. 2.00 or
later) or set a node
address below the
maximum.
No other nodes
exist.
Make sure that 2 or
more nodes exist
within the Network.
No node has been
set as the polling
node.
Refer to 9-1-2 Set-
ting the Polling and
Polled Nodes s and
set the Controller
Link Unit as the
polling node.
(If both types of
optical Units are
used in a network,
use the Optical
Ring Units as
polled nodes.)
The transmission
path format setting
is different in the
polling node.
Change the set-
ting to match the
one in the polling
node and turn the
power ON again.
