History Collection and Archiving
PlantScape can be configured to store the values of points at predetermined
intervals to create a history of process values. This process is known as history
collection and archiving.
This historical information can then be called up on a Station Trend display so
that operators can monitor the trends in the processes represented by those
points.
Note You might also want to use the event archiving option for event collection,
storage, and retrieval. For information about the event archiving system, refer to
“Configuring Extended Event Archiving” on page 383.
You can use Station to configure history collection for points. For points on
PlantScape Control Processors, this is the only way you can configure history
collection. For details, see “Viewing History Collection Configuration” on
page 169.
You use Quick Builder to define history collection for status, analog, or
accumulator points on other types of controllers.
Types of History Collection
When you configure a point to store historical values, the server scans the point
parameters at pre-determined intervals according to the following choices for
history collection:
•Standard
• Extended
•Fast
To define the type of history to be collected for a point, select one or more
history collection type check boxes for the parameters defined for a point. The
choices are described below.
Standard History
When you configure Standard History collection for a point, the following
snapshots and averages are stored:
• 1-minute snapshots
• 6-minute averages of the 1-minute snapshots
