Currently I am using PI DNP3 interface to collect data from some electric meters. Now I can see the real-time data values refreshing in "Current Value" tab in PI System Management Tool. However, I cannot see any previous records in "Archive Editor" tab. Is there anything to do with the setting of those points? In the "Points Builder" tab in PI SMT, there are some settings for archiving. What I did is just turning off the "Compressing", coz I want all of the raw data from meters. Am I missing anything here?
