I am thankful to all for your contributions. This forum page is helping me to clarify all my ongoing doubts and to explore the provided service..
From my formar posts, you might have observed that I am consuming PI Webservice and calling GetPIArchieveData.
But to full fill the ongoing requirements, I have to explore this service more closely. So I have a question for you now.
If I pass start date and end date, then I will get the values provided values should be available in that time range.
But what if I need value in my response even there are no values in that time range?
Start Date: 2010-12-03T00:00:00Z (YYYY-MM-DDTHH:mm:ss)
End Date: 2010-12-04T00:00:00Z
If there is no value in this time range, any any possibility (using PIArchMannar) to get last reads? That is on old date....i.e on date 2010-12-02?
Will any combination of "compressed + outside" or "Interpolated+ outside" work ? Can I get old values, if there is no values in provided time range?
