I have a digital tag from an OPC/UA device (advantech adam-6317). when I edit Tag Group from 'default' to any other group the Value shown in the tag browser shows "Uncertain\_InitialValue". i need this tag to be polled faster than 1second. it doesn't matter if I make the polling rate faster or slower. same result.

Is there anything obvious shown in the Tag Diagnostics? Are there any differences between your Tag Group and the `default` one, besides poll rate?
