View and reset Batch Transfer Periodic Aggregation Counters using the Batch Transfer Periodic Aggregation display

This Batch Transfer Periodic Aggregation display shows the Batch Transfer Periodic Aggregation current and previous values (Hourly, Daily, Monthly, Yearly, Total) for Indicated Volume (IV), Gross Standard Volume (GSV), and Mass across batch boundaries. For this information to be available, Periodic Aggregation should be enabled on the Batch Transfer.

Note: The RealTime and Historical Mass fields are only populated for products of type Ethylene. Therefore, aggregations for the Mass field are expected to show zero for non-Ethylene products.

The Hourly, Daily, Monthly, and Yearly fields are automatically reset at the top of each period. When a reset occurs, the previous value is updated to hold the current value, then the current value is set to zero.

The Total row keeps track of values across period boundaries. Total values do not get automatically reset.

On each reset (automatic or manual), the aggregated values are sent to the Historical database.

For more information on Historical tables used to persist Periodic Aggregations for Batch Transfers, refer to Understand the BatchXferPeriodicAggregation table details within the AVEVA Pipeline Operations for Liquids Administrator Guide documentation.
