Scenario: I have a PI Server (in L2) that acquires data from source systems (GE EMS System). I've observed that values for some tags in the L2 PI Server are being marked as "substituted" from the source. However, these same tags in the destination PI Server (corporate network) do not exhibit substitution when receiving data through the PI-to-PI Interface from the L2 PI Server. Query: I'm seeking guidance on how to address this data substitution inconsistency in destination PI Server. Determining if modifications to the PI-to-PI Interface or specific tag attributes are necessary to ensure consistent data transfer. Any insights or suggestions from the community would be greatly appreciated. P.S: Compression is not applied to any of those tags for a reason. Thank you,

Inconsistent Data Substitution Between Source PI Server and Destination PI Server

Scenario:

I have a PI Server (in L2) that acquires data from source systems (GE EMS System).
I've observed that values for some tags in the L2 PI Server are being marked as "substituted" from the source.
However, these same tags in the destination PI Server (corporate network) do not exhibit substitution when receiving data through the PI-to-PI Interface from the L2 PI Server.

Query:

Determining if modifications to the PI-to-PI Interface or specific tag attributes are necessary to ensure consistent data transfer.

Any insights or suggestions from the community would be greatly appreciated.
