027342 - ActiveFactory Trend and AFWorkbook show different values for the same time

Problem

Customer created an AF WOrkbook report to pull data from the historian every 15 minutes. When comparing the data to the trended info or from AF Query, the AF Workbook data is about 15 minutes behind in time.

Product Version: 9.2

Solution

We went through his AF Workbook function...step 3 of 4 has 2 tabs, 'Main Options' and 'Other'. After selecting the 'Other' tab, there is a section for Rules, and a TIme Stamp setting. The Time Stamp was set to "Start". We changed the Time Stamp to "End" and the AF Workbook function worked better and the timestamps matched the trends. Close.
