First Screen Checks

Browser HMI overview

Figure: The runtime-hosted HMI dashboard. Look here first for connection state, alarms, live values, and operator status.

  1. Confirm the connection badge is healthy.
  2. Confirm freshness is current enough for the task.
  3. Open the overview page before changing pages.
  4. Check alarms before forcing or acknowledging anything.
  5. Compare suspicious values against trends, runtime panel, or field state.

What This Page Is Not

This is not the HMI authoring workflow. Do not edit hmi/*.toml from an operator session. If the page layout or bindings are wrong, hand the issue to an engineering workflow and use HMI Authoring.

Success State

  • the HMI URL opens
  • connection and freshness indicators are visible
  • operator status, alarms, and live values are readable
  • the local runbook explains what the operator may acknowledge or change
