Regarding History trend view

[induna23]

Hi,

I just observed that the history trend view shows only the first value that is returned in the history response.

The History read request for a variable node Id from the UAExpert client is as follows :


ReadRawModifiedDetails->StartTime=[2012-09-10T02:30:00.000Z]


ReadRawModifiedDetails->EndTime=[2012-09-11T14:30:00.000Z]


ReadRawModifiedDetails->IsReadModified=[0]


ReadRawModifiedDetails->NumValuesPerNode=[10000]


ReadRawModifiedDetails->ReturnBounds=[1]



The Result the server sends back is :


NoOfDataValues = [3]


SourceTime = [2012-09-11T06:41:40.628Z]
Value = [10.300000]


SourceTime = [2012-09-11T06:46:34.527Z]
Value = [22.500000]


SourceTime = [2012-09-11T06:48:26.386Z]
Value = [35.799999]


But UAExpert only plots 10.3 (ie the first value returned ) in the UAExpert history trend view.

What could be the problem ?

Thanks & Regards,

Hello,

please check following:

- Do you use the most recent relase of the UaExpert (V 1.2.2)?

- Is the StatusCode of all values returned by the server Good?

- What does UaExpert trace when reading the history values?
(e.g. HistoryReadDataResults of node 'xyz' contains 3 values)

UaExpert only shows values with a Good status, otherwise the value is skipped.

Thanks for the help.
I downloaded latest version 1.2.2 and also updated the Status code while sending the data values.
Now I am able to view the history graph with all the history values.

Thanks & Regards,
