New Features

  • The Historian plugin card has a new Schema entry. It opens a page that lists the tables of the Historian database and their columns, with a link to the ready-made queries in the Topic Browser. The LLM Context button shows the schema, its rules and example queries as Markdown, to copy or download for an AI assistant.

Improvements

  • Historian bridges and the bridge templates with a write flow now subscribe to UMH topics beneath their own bridge location. Bridges that are already deployed keep their topics
  • Write flow topics can now be picked by data contract, version and tags
  • Long data contract names were cut off in the contract column and in its dropdown, so you couldn't tell which contract a row used. The dropdown now widens to fit the longest name, up to a cap. Names that still don't fit scroll slowly to their end when you hover them or move onto them with the arrow keys.
  • A Beckhoff ADS bridge now says under its Port that the port only checks that the PLC is reachable, and to use the PLC's web server port. Under the read type it says to use interval for hundreds of symbols.
  • Write flows now show a warning message, that they are not yet ready to be used in critical infrastructure.
  • A historian bridge subscribes to one version of one data contract, picked in the UMH topic table. Save to Historian on the data models page picks the latest version of the data model.
  • The search text is highlighted in the topic and folder names that match in the topic browser.
  • The historian status on the Data Models page now lists the data model versions that the historian bridge saves when you hover over it.
  • Updated the networking library golang.org/x/net to v0.62.0, which includes security fixes for HTTP/2 and HTML handling.

Fixes

  • Topic browser SQL queries now start from a tag's last value before the selected range and weight each value by how long it held, so tags that change rarely no longer show empty intervals or skewed averages
  • On new umh-core instances the password fields in bridges with UI-template will now be automatically hidden
  • Topics and folders in the topic browser tree are sorted by name and numbers in order again.
  • The topic browser tree scrolls to the selected topic when you return to the page.
  • The example table in the Historian Setup Guide is now readable in light mode
