The history collection function defines the module or node parameters that are monitored and stored in the DeltaV Continuous Historian.
History collection is an integral part of a module. If you copy a module that has history collection, the new module includes the history collection. This enables you to set up history collection for key parameters and copy the module for similar applications. Library modules include history collection so that you do not have to set up history collection when you copy a library module to an area. You can add additional history collection to a library module.
In earlier exercises, you set up history collection in Control Studio for the module that you created from scratch (LI-101) and acquired history collection for the other modules that you copied from the Library.
