I'm working on a PI System using some tags to monitor the PI server health. A tag was created to monitor the health of a PI Server. Initially the tag was a point type String. But I attempted to assign it to a multi-state symbol but failed to because of the Point type. So to solve the issue the point type was changed to Digital and was assigned a digital set. Then the tag was able to be assigned to a multi-state symbol. But after some time the tag's point type reverts to a string type. This has been going on maybe for a few weeks now. Whenever the point type is changed back to a digital tag after some time it reverts back to a string tag. The quickest I've observed this happen I believe has been within 30 minutes. Does anyone have any idea why this is occurring or how to solve this issue? Any suggestions or recommendations are appreciated.
