What is the effect of changing a PI Points Point Source?

Christine

I have data being brought into a PI Point with Point Source L. I want to backfill some data using the PI Interface for UFL. The Point Source configured in the interface of UFL is 'UFL'. The interface cannot find the PI Points to write to if it has a different point source it seems. How would I go about trying to backfill data using the Interface for UFL? Do I need to change the Point Source of the PI Point temporarily to 'UFL'? Would it still collect data from it's other data source if I did that?

    Hi. First, what other data source does the PI Point have, if it's using ptsrc=L? L or Lab is meant for manual input, not connected to interfaces or other data sources. I presume this other data source might be a custom application in that case, and if so, it's probably using the tag name or the PointID to access it. Then changing the Point Source doesn't affect the normal data collection, and you can go ahead and change to ptsrc=UFL
