Hi All,

I have a situation where i need to fetch very first value of a Pi Point and also it's time stamp

for example there is a pi point named : ABC and it is having number of values in it, now i want to find very first value written on that Pi Point

is there any method to find this ?

I am using .NET Framework 4.5 and C# or VB.Net

any one knows the method kindly share as soon as possible, it will be highly appreciated.

Thanks & Regards

Hello Sujit,

If you want to find the oldest value within a PI Point, please refer to code snippet below using PI AF SDK and C#:

This might not be the first value written on the PI Point since the events might be out of order.

Please let us know if this is what you are looking for.
