I'm using Proficy Historian Server 188.8.131.52 i need to buy data access components like oledb is there any specific version in oledb.
The Proficy Historian is not a product of OSIsoft, but from GE: GE Historian | Industrial Data Management Software | GE Digital
I'd suggest to contact GE or your local representative or reseller.
If i do remember correctly, OLEDB and/or ODBC is available for the Proficy Historian.
