Creating Niagara history import and history export descriptors is how you save a Niagara history to a different location (station) from where it originated. In a typical application, this is considered archiving. For example, an originating history (with a limited record count) may be in a JACE station. If imported to a supervisor station, its history import descriptor can be configured such that the imported history in the supervisor has “unlimited” record capacity. The JACE history can run collecting only the last 500 records, while the imported history in the supervisor will collect all (unlimited) records.

This section explains items unique to working with histories under a NiagaraNetwork.
