Force a refresh for all active conditions and inactive, unacknowledged conditions
whose event notifications match the filter of the event subscription.
Clients will often need to get the current condition information from the server,
particularly at client startup, for things such as a current alarm summary.
The OPC Event Server supports this requirement by resending the most recent event
notifications which satisfy the filter in the event subscription and which are
related to active and/or unacknowledged conditions. The client can then derive
the current condition status from the “refreshed” event notifications.
