It depends on which version of the historian. You can do this via the ADO.Net remote thing (using oledb,) via a custom .net GE Historian connector using their C# SDK (please contact Steve Alexander or me via e-mail if you are interested in this approach, since it requires a bit of configuration) or via their REST APIs, if you are using the historian version 7.0 or later.
Yes I would be interested in the ado.net remote thing. Do I need to download and install .net edge software and the ado services software? On the historian box.
Have you got the answer? Would you mind to teach me? I meet the same problem when I use the oledb. And it's my first time to connect ge historian.
Looking forward to your reply.
