I am using IHUAPI.dll in c#.net for fetching records from Proficy Historian Database. It gives me only 100,000 Records.

following is function i am using :

result= IHUAPI.ihuRetrieveSampledData(handle, tags, start, end,ihuSamplingMode.Trend,0, (uint)interval, out tagValues, out resultError);

I don't understand whether it is limitation of API or missing something ,Also i didn't find any docs related to this.

Anyone has gone through this ..!!

Thanks in advance.

    Given that ihuWriteData method has the following note: You cannot write more than 100,000 samples at in one call to this function, we can assume that it's API limitation. – Ulugbek Umirov Oct 16 '14 at 07:57
  • Thanks.. Yes ihuWriteData() has upto 100,000 records for write.But i am Retriving data from Historian, So not confirm of ihuRetrieveSampledData() method also has Limitations upto 100,000 records. – uttam palkar Oct 16 '14 at 12:30
