Hi Team,

We have PI OPC interface configured to receive data from PlantState Suite OPC-DA server. Data gets updated on OPC server everyday at around 6:00 AM and PI OPC interface scan class is configured with 24 hours frequency to receive data at 7:30 AM (f=24:00:00,07:30:00). Currently, we are facing issue where interface is reading 1 day older data (Example - 1/07/2019 7:30 timestamps value in PI matches with 30/06/2019 6:00 value in OPC). We have checked value on OPC server using PI OPC Client and it matches with OPC server value and timestamp. It looks like issue with PI OPC interface. Kindly assist.
