We are seeing "PIPointInvalidException [-12002] Code Not Found in PInt" and "PIPointInvalidException [-11147] Point ID not found in archive".  When looking into the archives using SMT, we can see that there is in fact data in the archive for the tag names.


We know that the PI Tag Attribute "Point Type" has recently been changed from Float32 to Int32 using AFSDK (piPoint.SetAttribute("PointType", PIPointType.Int32);).  Is this the reason for these errors? 


What do these error messages mean and how to resolve them?


What should we expect to see when changing point types?


Is there a recommended procedure for changing point types of existing tags?
