SAP MII 11.5 to 12.2 Migration Extended PI API Functionality Replacement Suggestions

We are in the process of migrating from SAP MII 11.5 to 12.2  as a result of this migration functionality for use of extended API calls was not carried forward to the PCo connector which is not based on the PI-SDK.  For most things we can use PI-OLEDB classic to accomplish what we need.  However, we made extensive use of the API call piar_timedvaluesfil to in our condition based maintenance(CBM) application to calculate equipment run time.  Since MII no longer supports this I am look for solutions that I could leverage through PI-OLEDB classic, the PI Web API or PI Web Services which are tag based to accomplish the same thing.  I have found ways to do simple 1 tag solution with PE expressions through PI-OLEDB Classic(i.e. TIMEEQ, TIMELT, TIMEGT, etc), but need to support more complex scenios that would use a filter expression like the original API call did.

 

Any suggestions would be greatly appreciated.
