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.

 

Example:

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
22-Mar-15 17:04:22242
22-Mar-15 17:04:2127

 

Regards,

 

Yasin
