  3.1.8 interpolated bounding values
  interpolated bounding values bounding values determined by a calculation using the nearest Good value Note 1 to entry:  Interpolated Bounding Values using SlopedInterpolation are calculated as follows ... search a time range which is at least the size of the ProcessingInterval. Interpolated Bounding Values using SlopedExtrapolation are calculated as follows: find the first non-Bad Raw value before

  3.1.7 bounding values
  ways to determine Bounding Values for an interval. One way (called Interpolated Bounding Values ) uses the first non-Bad data points found before and after the timestamp to estimate ... portion is determined by the rules specified by the bound or Aggregate . The Interpolated Bounding Values approach (see 3.1.8 ) is the same as what is used in Classic OPC Historical

  5.4.3.6 TimeAverage
  TimeAverage The TimeAverage Aggregate defined in Table 54 uses Interpolated Bounding Values (see 3.1.8 ) to find the value of a point at the beginning and end of an interval. Starting ... Values exist in the interval then they are omitted from the calculation and the StatusCode is set to Uncertain_DataSubNormal . Sloped lines are drawn between the Good values when calculating
