The answer is unfortunately no. Depending on your application you can have your MDB synced with your AF Server and might be able to access what you want through a path pointing to an AF attribute. Here is an excerpt from PI Web Services Users' Manual:
The Web service provides two interfaces:
- IPITimeSeries – for the retrieval of time series data supported by the PI System. This includes PI points and time series data referenced by AF Attributes. Future releases will add support for the other major PI System data types.
- IPISearch – for searches the PI System that yield search results consisting of paths for use with IPITimeSeries.
