I have 5 tags that are all triggered to change in a ControlLogix at the same time. These same values are also objects in Archestra System Platform, which have the history extension enabled. Roughly, I have a coil complete trigger in the PLC which updates time, total length, good length, scrap length and bar-code value. When viewing historical data, I can open a trend in WW Historian Client and add these objects, then select "past week" and then right click the trend and select Data Log - Wide format. This gives me a nice log of all those values in a spreadsheet form, EXCEPT, every now and then one of the values will be updated a tenth of a second later than the other values and will create a separate row for that value, which can be somewhat confusing. I've tried using the WW Query program to align all the values, but I'm not too familiar with SQL. I'm not sure if this is something I need to change in the WW historical setting, or something that could be cleaned up in the WW Query program. Any suggestions?
Thanks
