Periodic Event Dimension Update

For long production events, it may be desirable to monitor event progress during the course of an event. For example, you may want to track the quantity manufactured or other variables that control alarms.

Control of Periodic Event Dimension Updating

In Plant Applications 6.1.4 (April 2015), 6.2.3 (July 2015), and 6.3, a new Auto Move End Time (Minutes) configuration parameter is added to the Production Event model to automatically adjust the end time of an event, while the event is in process, and to update event dimensions. “In process” means that an event is available for consumption. Data collection is done when an event is created or the end time changes, regardless of the associated status. But now for events that have an “in-process” status, the following actions are taken:

  • Data collection (updating dimensions, which may involve calculations) and updating is not done by default and only done when the Ignore Event Status flag for a variable is turned on.

  • History recording is controlled by certain site parameters. A new value, History Based on Event Status, is added so that the status of the related event is checked every time a record changes.  If the Bypass History flag is selected for any Event Status, history is not recorded.  

Setting Up Periodic Event Dimension Updating

Follow these steps using the Plant Applications Administrator to set up periodic event dimension updating:

  1. In the General tab of an Edit Model screen (event configuration) for a Production Event, set the Auto Move End Time (Minutes) value to determine the interval at which the end time is automatically moved. The parameter tells the Event Manager to move the end time for the latest event on the unit as long as the event is “in process.”  Setting the parameter to a value of “0” (zero) disables the auto-move function.

  2. In the Site Parameters screen accessed from Global Configuration, set the Value for any of the following Site Parameters to History Based on Event Status for events for which you want to selectively turn off history recording through an Event Status:    

    • Populate Event_Detail_History

    • Populate Event_History

    • Populate Test_History

    • Populate Waste_Event_Detail_History

  3. Define or change an event status through Administer Production Status under Global Configuration, and select Bypass Event to stop history recording.

  4. Associate production statuses (Productions Statuses tab) with a unit by right-clicking on a unit in the Plant Model and selecting Edit <unit> Properties to display the Properties Configuration screen for a unit. Production statuses having the Bypass History flag do not record history.

  5. For selected variables in the Variables Sheet, accessed from a Production Unit, select the Ignore Event Status option to collect data for “in-process” events when using event status to turn off control data collection.
