I setup a single historical tag. The historical data doesn’t seem to return values after the start of October. The values are currently being written into the database but when an EasyChart is bound to the Historical Tag, it only returns values up to 10/1/2010 11:59:59 pm and the rest of the chart is not populated. I also tried a Table Tag History binding. As soon as I specify the end date into October (>10/1/2010 5:00 am), no values are returned and the query times out. When choosing start and end times both in October, the queries also time out.
While trying to configure the historian, I did change the partition units from month to week, and I know I deleted tag history and then added again in the designer. Not exactly sure what the sequence was. I’m pretty sure the partition tracking may have gone a little whacky.
I configured this tag the last week of Sept. and I have three tables:
The last table is currently being populated. Any ideas what might have caused this or how to recover?
