Processing raw data stored in an historian device for determining an amount of products passed through a process element in a process control environment is described. A count value is incremented by a counter at a rate at which products pass through the process element. The count value rolls over to zero when the count value reaches a rollover value R. An historian device periodically receives count value data points from the counter. A deadband value D is set in the historian device for distinguishing between rollovers, resets, and reversals. A client device queries the historian device for an amount of products passed through the process element for a timeframe. The historian device selects a set of count value data points from within the queried timeframe. The historian device determines, based on the selected data points and their quality, an amount of products passed through the process element.

An object of the present invention is to prevent rejection of a subsequent paper sheet even if counting of paper sheets is accelerated. Provided is a paper sheet handling system including a paper sheet identification device that identifies paper sheets, and a paper sheet counting device that counts the paper sheets identified by the paper sheet identification device. The paper sheet handling system generates previous process data including read specific codes in the order of fed paper sheets, and memorizes therein the feed-out number K of paper sheets that have been already fed at the point in time when a specific code of one paper sheet is read. A batch quantity N is an integer larger than the feed-out number K. Every time the specific code is read, the specific code is matched with the previous process data, to specify the Zth paper sheet from the paper sheet with the matched specific code as a batch expected paper sheet. Specific codes from the batch expected paper sheet to the paper sheet K before thereof are extracted from the previous process data. When it is judged that any of the specific codes from the batch expected paper sheet to the paper sheet K before thereof matches with the read specific code, an operation of a second feeding unit is stopped.
