Troubleshooting Using Indicators
Section 10-1
Node Cannot Participate in Data Link
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.
Data Link Cannot be Stopped
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.
Note Stop the data link from the node at which the LNK indicator is lit (indicating
active data links). Data links cannot be stopped from nodes which do not have
active data links.

Refer to 5-2-2 Manual Setting
and remake 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.)
Refer to 5-2-4 Automatic Set-
ting: Select All, 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.
When automatic setting is
used, the local node is not set
to participate in the data link at
the startup node.
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.

When manual setting is used,
there are no data link tables
set for the local node.
Set data link tables for the
local node.
