Hello Folks,


Greetings for the day!


Using PI ACE (VB.NET), I would like to know if the value for a given tags has been updated from past 15 mins.

Is there any method in ACE that would do the same. Or How could I write a look to pull the values by providing the starttime and end time and loop around by comparing the 2 values.


Note: I am using PI Module database to configure the signals (Input_Aliases).


Thanks in Advance.


Thanks & Regards,
