I want to read the timestamp of the value of a lab tag as a tag through an OPC server.
For example,i have the lab tag "Baka" and its current value is 10 with a timestamp of 2/11/2017 07:00:00 AM.
So i created a PE tag (with no compression or exception) and its excdesc== "Prevevent('Baka','*') which works in Processbook.
I get the "2/11/2017 07:00:00 AM" as the value of my new tag. The problem is (probably a format issue) that when i try to read this new tag from another server through an opc connection i get the value of 1478062848.
The same value i get in excel using datalink (1478062848).
Thank you in advance!
