When i start the interface, i got this message: "Error [-10400] loading points. pipt_nextptwsourcelong failed for point source OPC
That usually means that the interface does not have enough permissions on the PI Server. Please check your trusts.
I am moving this thread to All Things PI > PI Interfaces.
You can refer to this link to configure access to your PI Server for the OPC interface.
My PI trust is created as piadmin. Still I'm seeing the above mentioned error. Also, I'm getting partial data from the interface too.
You should check to see what identity that your interface receives when connecting to the PI Data Archive in Network Manager Statistics as shown in this video- OSIsoft: Advanced PI Data Archive Security Troubleshooting- Check Connections/Permissions in PI SMT - YouTube. Also, it is not best practice to use piadmin. You would want to create a custom identity and give it the minimum permissions needed- https://techsupport.osisoft.com/Troubleshooting/KB/KB00833).
