The DeltaV system supports the collection of user-specified parameter field values, alarms, and events for long-term storage, retrieval, and presentation. There are three main aspects of historical data collection and presentation:
Detection by defining history collection in the modules and nodes
Storage by the Continuous Historian subsystem
Presentation through the Process History View application
The DeltaV system also lets you export data to the Microsoft Excel spreadsheet software so that you can use that application's extensive analysis and reporting features.
