3.1.1 ProcessingInterval

ProcessingInterval timespan for which derived values are produced based on a specified Aggregate Note 1 to entry: The total time domain specified for ReadProcessed is divided by the ProcessingInterval ... would result in a set of three intervals of ProcessingInterval length, with each interval having a start time of 12:00, 12:10 and 12:20 respectively. The rules used

6.5.4.2 Read processed functionality

more HistoricalDataNodes . The time domain is divided into intervals of duration ProcessingInterval . The specified Aggregate Type is calculated for each interval beginning with startTime by using the data within ... next ProcessingInterval . For example, this function can provide hourly statistics such as Maximum, Minimum, and Average for each item during the specified time domain when ProcessingInterval is 1 hour

5.4.2.2 Generating intervals

read Historical Aggregates , OPC clients shall specify three time parameters: startTime (Start) endTime (End) ProcessingInterval (Int) The OPC Server shall use these three parameters to generate a sequence of time ... means the value will be the same except the timestamps are shifted by one ProcessingInterval . E.g. when time flows forward the value at T = n is the same
