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 LNK indicator on the front of the Board.
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. The M/A indicator is only available in the
Controller Link Unit and cannot be used in the Controller Link Support Board.
Refer to
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
computer or the Controller Link Support Board.
Data link status can be monitored using the CLK Data Link Setting Utility in
FinsGateway or it can be stored in FinsGateway event memory. Refer to the
FinsGateway online help and installation guide for details.
