Controls whether VTScada will log the full, translated description of an alarm in an alarm record, in addition to logging the description's PhraseID (if there is one). The setting also tells the Alarm Page whether to display the legacy Description field in the alarm record, or just display the translated PhraseID.
This property is set to 1 (TRUE) in any new application added since 11.5 / 12.0. All older applications will default this setting to 0 (FALSE).
For new applications, which use PhraseIDs for their descriptions, all that needs to be logged is the PhraseID. Logging the translated description is a waste of resources and therefore NoLegacyAlarmDesc should be set to 1.
In legacy applications, whose descriptions were configured prior to the existence of the concept of PhraseIDs, all the historical alarm records have the alarm description stored in the legacy Description field and therefore NoLegacyAlarmDesc should be set to 0.
It is more efficient for an application to set NoLegacyAlarmDesc = 1.
