Not lit Terminating resistance is
not set correctly.
Turn ON the terminating
resistance at the nodes at
both ends of the Network
and turn it OFF at all other
nodes.
Cables are not connected
correctly.
Check the cable connec-
tions and reconnect cor-
rectly.
The node address is larger
than the maximum node
address set for the network
parameters.
Either reset the maximum
node address using the
Controller Link Support
Software or reset the node
address to below the maxi-
mum.
No other nodes exist.
Make sure that 2 or more
nodes exist within the Net-
work.
No nodes have been set as
polling nodes.
and set at least one polling
node. (Controller Link
Units should normally be
set as polling nodes.)
The set baud rate is differ-
ent to other nodes (Wired
Unit).
and set all nodes on
the network to the same
baud rate.
