I've encountered a strange problem - after I write a value to PI via UpdateValue() it is available for some minutes(seconds?) but then completely disappears. I presume it might be that it gets into the Snapshot but is refused to be written to Archive. That's strange because archiving is on and compression is completely off. What could be the reasons for such behaviour?
