Troubleshooting Using Indicators
Note Stop the data link from the node at which the LNK indicator is lit (indicating
The following table describes the LNK and M/A indicators when a node can-
not participate in the data links.
Data link participation depends on the Controller Link Unit operating normally
and participating in the Network. Refer to Troubleshooting with RUN, ERC,
ERH and INS Indicators earlier in this section and check Unit operation before
using the following table.
Stopping the data link depends on the Controller Link Unit operating normally
and participating in the Network. Read the above explanations before
attempting to stop operation.
active data links). Data links cannot be stopped from nodes which do not have
active data links.
To configure a network that uses a node address higher than 32, all nodes
must be CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, CJ1W-CLK23,
3G8F7-CLK21-V1, or 3G8F7-CLK23-E. The Wired Network 62 Node Enable
Bit in the DM Parameters Area must also be turned ON (62 nodes max.) for all
nodes. If the nodes are set differently, the network will not be configured cor-
rectly. If the settings are incorrect, the following problems will occur.

Data link operating normally.
When manual setting is used,
there is an error in the data link
table.
When automatic setting is
used, the data link parameters
at the startup node are incor-
rect for the local node (the
data link area is out of range
for the local node.)
When automatic setting is
used, the local node is not set
to participate in the data link at
the startup node.
Automatic setting is used with
1:N allocations, but the device
does not support this function.
When a number exceeding
12,000 was set for the data
link send and receive words or
the same memory area was
set for Area 1 and Area 2
using a CS/CJ-series Control-
ler Link Unit with unit version
1.2 or later that was then
replaced with a CS/CJ-series
pre-Ver. 1.2 Controller Link
Unit.
When manual setting is used,
there are no data link tables
set for the local node.
Probable cause
---
Refer to 5-2-2 Manual Setting
and remake the data link table.
Refer to 5-2-4 Automatic Set-
ting, reset the parameters for
the startup node DM Area so
that the local node can partici-
pate in the data link, and then
restart the data link.
Stop the data link, reset the
parameters for the startup
node DM Area so that the local
node can participate in the
data link, and then restart the
data link.
Use a Controller Link Unit that
supports automatic data link
creation with 1:N allocations.
Refer to Automatic Setting on
page 131 for details.
The number of data link send
and receive words cannot
exceed 12,000 and the same
memory area cannot be set for
Area 1 and Area 2 when using
a CS/CJ-series pre-Ver. 1.2
Controller Link Unit. Either use
a CS/CJ-series Controller Link
Unit with unit version 1.2 or
later or reset the data link
tables.
Set data link tables for the
local node.
