Can the 800xA History server fetch log data from 800xA Basic History ?
When using 800xA for Advant Master, Time Tagged Data (TTD) are stored in 800xA Basic History. Question: Can the Data Collector Nodes, for the 800xA History server, fetch data from 800xA Basic History ? in a way so that the 800xA History server can be used for long time storage af 800xA Basic History data (and thereby long time storage of 800xA for Advant Master TTD logs) ?

The Data Collector Nodes will fetch the OPC DA from System 800xA OPCSurrogate service and stores in it and forwards to History server.
The Data collector nodes will not read any data from 800xA Basic History (either TTD logs) and it is not required to configure TTD logs as well.
In case of IM, collects data from TTD. But in case of 800xA History it will directly connects to OPC source of system 800xA.
