I have created a database to store the alarms and events. In the "Alarm and Event Historian Database Properties", i have checked Archived events older than:" and set to 1day. Then run the application for some time. To save time and prevent long wait, i change the date of my computer to 1day faster than the exact date. Supposedly, the alarm data will be archived and save in the specified location. However, i don't see any archive file created in the specified location. Anyone has solution to this problem?? Your help will be appreciated.
