DESCRIPTION

Synchronizes the entries of the Eventlog in the runtime area against the stored _EVENTLOG.DBF.
The File is read record by record and missing ones are added to the runtime. The alarm summary and the actual conditions of data objects are not affected by the "Usr_EventlogRstr()" action.

The file "_EVENTLOG.DBF" is a ring buffer in which events are stored – on system stop the entries are kept and recording is continued on restarting the system.
Generally only events since system restart are shown in the Eventlog, to display events from previous sessions use the above job to list any event that is still stored.
