UNS Explorer

Browse live tag values, quality indicators, and history in the Unified Namespace.

UNS Explorer (/uns) is the live view of all tag paths across your plants.

Browse the tree

  1. Open UNS Explorer from the sidebar
  2. Expand plant → machine → device → tag nodes
  3. Click a tag to see its current value, quality, and unit

Live values

Values update from the Redis latest-value cache. Quality indicators show data health:

QualityMeaning
GOODValid reading
BADInvalid or out-of-range
UNCERTAINQuestionable reading
TIMEOUTNo response from source
DISCONNECTEDDevice not reporting
CONFIG_ERRORTag or adapter misconfiguration

Inactive tags are hidden from the tree by default. Only active tags receive live updates — see Active and inactive tags.

Tree layout and pagination

Large plants can use Classic tree mode for a compact folder-style hierarchy. When a device has many tags, the values panel paginates results and offers Show more to load additional rows without scanning the full Redis hash.

History

Select a tag and open the history panel to query time-series data from PostgreSQL. Useful for troubleshooting rule triggers and verifying adapter output.

You can overlay up to four tag paths. The URL stores them as ?paths=plant/a,plant/b plus optional windowMinutes (15, 120, or 480). Use Copy link to share the same series in another browser.

Search and filter

Use the search box to find tags by path fragment. Plant-scoped users see only tags within their assigned plant and UNS path filter.

Permissions

Requires tags.read permission. Export requires telemetry.export.
