Communication alarms

The communication line between the RTU and the host computer may encounter minor errors and problems. The details from all communication alarms and events are recorded in the Historical database (HDB).

The statistics for communication errors are recorded in the Remote table, and then transferred to the HDB’s CommStats database, where they are stored in the RemPeriodStats table. The connection statistics are recorded in the Connection table, and then transferred to the HDB’s CommStats database, where they are stored in the ConnPeriodStats table.

To view Historical results, select any field of a record’s information line on the Remote Summary window in easy eXtended Operator Station (ezXOS). When the action menu appears, select Historical Statistics to open the Communications Statistics Edit dialog box that displays Historical results.
