Loading /Backfilling data from Uniformance PHD server using OPC HDA interface

Hi All,

We have a client requirement where we need to load / backfill data of last 7 years from Uniformance PHD server for aroung 2500 Tags in to PI server.

Here i am considering to use PI OPC HDA interface to load data from PHD server by creating a 5 Interface instance i.e. one instance for 500 tags and loading data in batches of a year.

Please share your experiances and expertise on this topic & please suggest any alternate solution if you think this is not the best one.

Thanks for your help in advance.

Regards

Vijay
