Checking Data Link Status
Make sure that the LNK
indicator is ON at nodes
participating in the active data
links.

Data links can be stopped by sending the FINS command “STOP.” The node
to which the FINS command is issued must be participating in the data link.
There are two methods for checking the status of active data links:
Check the LINK and M/A indicators on the front of the unit.
The LNK indicator will be lit at all node participating in the data links as long
as operation is normal. The data link mode (manual/automatic) can be
checked using the M/A indicator. See 9-1 Troubleshooting Using Indicators for
details.
The data link status area can be used to check for errors when data link does
not operate normally even though no abnormality has been detected by the
PLC’s CPU Unit or the Controller Link Unit. The data link status area contains
the data link status information shown below.
The number of words used for data link status and the information that is
reflected depends on the setting (8-bit or 4-bit format) for the data link status
storage format specification in the DM Parameters Area, as shown in the fol-
lowing diagram.
See 9-2 Status Area and Troubleshooting for troubleshooting procedures and
see Data Link Status Storage Format (CS/CJ Series Only) for details on set-
ting the data link status storage format in the DM Parameters Area when
using CS- and CJ-series PLCs.
