Robust OPC-HDA client library/component/object?

[Pete.S.]

Hi guys!

We need to pull historic data into an application using OPC-HDA.

Searching the net I find plenty of OPC-DA client libraries/components/objects but no OPC-HDA for historic data access. Do you know of any or can recommend anything?

My primary concern is stability - it has to be rock solid.

Thanks,
Pete

Last year I was searching for an OPD SDK and found this:

They offer evaluation software (you have to restart after 30 mins). I did not try the software as I had to move to a different project.
