How can I export tag data? I don't have excel as on PI DL.
I want to compare a number of trends with same sampling intervals.
Step 1: Open PI System Explorer
Step 2 : Select the attribute (tag reference ) you want to extract sample data
Step 3: Right Click and Select Time Series Data
Step 4 : Select Sample tab
Step 5 : copy the data.
Is it possible to get the data before its compressed and filtered?
Compression is done on data at the point it moves from snapshot to archives. At this point, the data that is compressed out is discarded. There is no way to retroactively retrieve the data that was compressed out.
To archive all values for any given tag, compression and exception should be disabled in order to archive all values moving forward.
