Checking Data Link Status Section 5-4
Issuing the FINS Command from CVM1, CV-series, CS/CJ-series, and CQM1H-series PCs
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.
5-4 Checking Data Link Status
There are two methods for checking the status of active data links:
• Check the LED indicators on the front of the Units.
• Check the data link status area.
5-4-1 LED Indicators
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.
5-4-2 Data Link Status Area
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
PC’s CPU Unit or the Controller Link Unit. The data link status area contains
the data link status information shown below. This status information is stored
in the same words for C200HX/HG/HE PCs, CS/CJ-series, CVM1, CV-series,
and CQM1H-series PCs.
See 9-2 Status Area and Troubleshooting for troubleshooting procedures.
