- Specify the calculation period for the integral value

- Period—Specify the period of time (in seconds) for which the Field Device should calculate the integral value. Enter the required interval in the OPC Time Format. You can enter the value directly in the field, or use the Interval window (accessed via the field's browse button) to specify the required value.

The start of the week is Monday at 00:00:00 UTC (that is, midnight between Sunday and Monday).Enter the required interval in the OPC Time Format. You can enter the value directly in the field, or use the Interval window (accessed via the field's browse button) to specify the required value.
Example 1:
Period: 1H, Offset: 0
Simple hourly integral, synchronized to the hour boundary.
Example 2:
Period: 1D, Offset: 6H

- Log End of Period—Use this check box to specify whether you want the Field Device to log the integral value at the end of the specified Period. That is, before the End of Period Reset (see End of Period in the ClearSCADA Guide to Core Point Configuration). If you do this, the Field Device will log the total in each Period. Select the check box to enable logging. Clear the check box to disable logging.
