Our OPC server had an 8 hour outrage about 16 hours ago, now I need do a history recovery to fill in the data gap. Can you just simply set the History Recovery Maximum Time to 24 hours and restart the OPC HDA interfaces? Will the current tag values continue flow in? Will the history recovery overwrite the existing tag values?
