Local Historian is generally for customers with remote site nodes in geographically distributed SCADA intermittent networks. It provides functionality that can replace Store & Forward which can have issues on intermittent networks.
This is for data collection and storage at the local node only which will then be typically replicated to a Tier 2 Historian at the main site. Remote IDAS is not enabled. Data older than the last 7 days is not accessible on Local Historian. Local Historian includes a DAServer license. A Platform, if needed, must be purchased separately. If user has Historian Client at the remote site node and wants to see data beyond the 7 day limit, they simply redirect gathering of data to the Tier 2 Historian at main site.
