Does GeoSCADA support OPC UA HDA (Historical Data Access) drivers

[sbogavilli]

Hello all,

I am looking for some help on the GeoSCADA OPC UA HDA driver's connectivity to access historical data from our client server. In our previous projects, we used the AirODBC protocol to access historical data from our client server (via ODBC). GeoSCADA AirODBC driver is now superseded, and we do not want to use WindODBC protocol; instead, we want to access the data using OPC UA HDA. Can anyone please confirm if the GeoSCADA supports OPC UA HDA drivers and if anyone tested in the real world?

Thanks all in advance.

Kind regards,

Sam

The Geo SCADA OPC UA client driver does not support historical data (part 11 of the OPC UA standard), it only supports current data (part 8) and discovery services (part 12).
