    How to set an element attribute value with a system digital state?


      Hi folks,

      I tried to send a system digital state to an attribute, which is associated to a Float32 PI Point. Here is the part of the code I used for this:


                              Dim sysStateSet As Asset.AFEnumerationSet = OSIsoft.AF.Asset.AFEnumerationSet.SystemStateSet
                              Dim enumSystemValue As Asset.AFEnumerationValue = sysStateSet(value)
                              If enumSystemValue <> Nothing Then
                                  afValue = New Asset.AFValue(enumSystemValue, timeStamp)
                                  Throw New Exception("Value type does not match attribute type nor the possible value existing in the system digital state set.")
                              End If


      I set the "value" variable with "No Data". The objects afAttr and timeStamp have already been set.


      When the code is executed, I see the number 248 in the archive (which corresponds to the "No Data" system digital state number). I was expecting to see "No Data" instead.


      What am I doing wrong?
