The UAMonitoredItemArguments class contains a Boolean AutoConditionRefresh property. When set (this is the default), a UA ConditionRefresh will be automatically performed when needed to keep the condition information up-to-date.
The component handles special events reserved for condition refresh automatically, and translates them to event notifications with a special form of event arguments. Event notifications (EasyUAEventNotificationArgs) that related to condition refresh have their Refresh property set to ‘true’. In addition, a start of condition refresh is indicated by a notification with event arguments that have their RefreshInitiated property set to ‘true’. Correspondingly, an end of condition refresh is indicated by a notification with event arguments that have their RefreshComplete property set to ‘true’.
