Troubleshooting Using Indicators Section 9-1
Lit --- --- Not lit Terminating resistance is
not set correctly. (Wired
Unit)
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 are 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.
Refer to 8-1-2 Setting the
Polling and Polled 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).
Refer to Section SEC-
TION 4 Preparations for
Communications and reset
the baud rate.
The Wired Network 62
Node Enable Bit is ON in
some nodes and OFF in
other nodes in the network.
When using node address
33 or higher, turn ON the
Wired Network 62 Node
Enable Bit in all the nodes,
then turn the power supply
OFF and ON again.
When using node address
33 or higher, configure the
network so that all nodes
are CS1W-CLK21-V1,
CJ1W-CLK21-V1, or
3G8F7-CLK21-V1. The
CS1W-CLK21, CJ1W-
CLK21, C200HW-CLK21,
CVM1-CLK21, or CQM1H-
CLK21 cannot be used.
