Hi, I have a following problem. I insert values in PI with AF Sdk 2016 using :


var point = PIPoint.FindPIPoint(_piServer, tagName); 
point.UpdateValues(afValues, AFUpdateOption.Replace, AFBufferOption.DoNotBuffer);


I need to retrieve the inserted values shortly after the insert is done:


 point.RecordedValues(new AFTimeRange(GetAFTimeLocal(start), GetAFTimeLocal(end)), type, null, true);



Sometimes I cannot read the values for several minutes, they are not visible in PI SMT too. After that they appear.
The values are for the past and writting application is running on the same machine the PI Server is. I see such behavior for the first time. Is there an explanation why is this happenning and how can be avoided?


Thank you in advance!
