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 us-
ing 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. See 9-1 Trouble-
shooting 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 comput-
er or the Controller Link Support Board.
Data link status can be monitored using the CLK Data Link Setting Utility in Fins-
Gateway or it can be stored in FinsGateway event memory. Refer to the Fins-
Gateway online help and installation guide for details.
