If an AppEngine is deployed before Historian is started, history data can be stored locally by HCAL until the objects successfully register with the Historian.
Note: Except for Late Data, a ViewEngine object contains the same historical attributes as an AppEngine object. A WebViewEngine object does not store any historical data.
