ObixHistoryDeviceExt (default name Histories) is a frozen device extension of the ObixClient and R2ObixClient component. It allows the import of historical data from the oBIX server into the NiagaraAX history space. Use its default ObixHistoryManager view to add ObixHistoryImport descriptors.

See “About the Histories extension” and “History Import Manager” in the Drivers Guide for general information. For details specific to an R2ObixClient, see the “R2ObixClient Histories (logs and archives)” section in the engineering notes document Niagara R2 to NiagaraAX via oBIX.
