IEC 62541-13:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62541-13:2025 defines the information model associated with Aggregates. Programmatically produced aggregate examples are listed in Annex A. This third edition cancels and replaces the second edition published in 2020. This edition constitutes a technical revision. This edition includes the following technical changes with respect to the previous edition: a) Multiple fixes for the computation of aggregates • The Raw status bit is always set for non-bad StatusCodes for the Start and End aggregates. • Entries in the Interpolative examples Tables A2.2 Historian1, Historian2, and Historian3 have been changed from Good to Good, Raw status codes when the timestamp matches with the timestamp of the data source. • Missing tables have been added for DurationInStateZero and DurationInStateNonZero. • The value of zero has been removed for results with a StatusCode of bad. • Data Type was listed as "Status Code" when it is "Double" for both Standard Deviation and both Variance Aggregates. • Rounding Error in TimeAverage and TimeAverage2 have been corrected. • The status codes have been corrected for the last two intervals and the value has been corrected in the last interval. • The wording has been changed to be more consistent with the certification testing tool. • UsedSlopedExtrapolation set to true for Historian2 and all examples locations needed new values or status are modified. • Values affected by percent good and percent bad have been updated. • PercentGood/PercentBad are now accounted for in the calculation. • TimeAverage uses SlopedInterpolation but the Time aggregate is incorrectly allowed to used Stepped Interpolation. • Partial bit is now correctly calculated. • Unclear sentence was removed. • Examples have been moved to a CSV. • The value and status code for Historian 3 have been updated. • TimeAverage2 Historian1 now takes uncertain regions into account when calculating StatusCodes. • TimeAverage2 Historian2 now takes uncertain regions into account when calculating StatusCodes. • Total2 Historian1 now takes uncertain regions into account when calculating StatusCodes • Total2 Historian2 now takes uncertain regions into account when calculating StatusCodes • Maximum2 Historian1 now takes uncertain regions into account when calculating StatusCodes • MaximumActualTime2 Historian1 now takes uncertain regions into account when calculating StatusCodes • Minimum2 Historian1 now takes uncertain regions into account when calculating StatusCodes • MinimumActualTime2 Historian1 now has the StatusCodes calculated while using the TreatUncertainAsBad flag. • Range2 Historian1 now looks at TreatUncertainAsBad in the calculation of the StatusCodes. • Clarifications have been made to the text defining how PercentGood/PercentBad are used. The table values and StatusCodes of the TimeAverage2 and Total2 aggregates have been corrected.
