I am using an UpdateValue(s) call to delete a series of PI Tag Values in a time range, and then shortly following that performing a series of UpdateValue(s) calls to repopulate the time range. However I am getting a a number of error messages in the log file

 

eg. "SnapshotDeleteEvent, PtID: 452, Event Time: 10-Jan-17 02:08:25, Status: [-11133] New snapshot event received while pending delete"

 

The point being the one that the code is working with.

 

I am also noticing that InterpolatedValue calls made shortly after this are returning unreliable results.

 

Is the PIPoint.UpdateValue(s) call asynchronous, if so is there a way to force it to by synchronous?

 

Thanks in advance.
