Hi All,


I'm trying to write a expression in PI Datalink to pull only unique values with last timestamp i.e, duplicate values to be removed and result only with unique values.



Raw Data from PI Datalink.



Expected Value after filter expression in PI Datalink is,


Number of Values:5
01-Apr-15 10:20:0617
22-Mar-15 17:04:24405
22-Mar-15 17:04:23270
