I am facing an issue for pulling interpolated values from PI by using History mode.
My requirement is to pull 5:30 am data from PI.Since data is coming to PI from DCS,so there are lots of entries for each day.
But I want 5:30 am interpolated data.
Suppose I am pulling March month data.
So in Tag Query,I did the following steps:
1) History mode
2) Start date as 1st march 5:30 am and End Date as 31st March 5:30 am and rowcount as 31.
It is not giving me 5:30 am interpolated data.only ist row and last row are coming 5:30 am.Other rows are not giving 5:30 am data.
I am facing this issue only for March month.For other months,it is working fine.
Problem is for 11th March.If I select 12th March to 31st March,it is working fine.If I select 1st march to 10th March,it is working fine.
So I would like to know is it because of any data?
Any idea why it is happening?
Thanks & Regards
