Rockwell Automation FactoryTalk Metrics User Guide - Manual (Page 262)

Appendix A Report Data Sources
• Shift information.
• The OEE calculation for that period of time.
• The value for each configured user-defined summarization
criterion.
Records will be created as long as FactoryTalk Metrics is collecting
data—24 hours a day, 7 days a week, whether the monitored
equipment is running or not. The Performance Data Trending
Rate interval selected for an activity area specifies the duration of
the Workcell History record. The current record is updated every 10
seconds with new performance information. When the Performance
Data Trending Rate interval has passed, the current record is closed
and a new record is created. The current Workcell History record
will also be closed and a new one will be created if any of the
following occurs:
• The scheduled shift changes.
• The Scheduled Availability status for the activity area changes.
• The number of the part that the activity area is building
changes.
• The value of a configured user-defined summarization
criterion changes.
• The ideal cycle time changes.
• Data collection stops (a new record is not created).
Since there is one record in the database for each activity area for
each Performance Data Trending Rate interval, it is not possible to
report on periods of time less than the specified rate. For example, if
the Performance Data Trending Rate for the activity area is set to 10
minutes and you try to report on Workcell History data between
12:00 and 12:05, you will get data between 12:00 and 12:10.
