Hmi Runtime Overview

Goal

Section titled “Goal”

View a project’s HMI screens running against a live runtime, so the components show real values and accept operator input.

Before you start

Section titled “Before you start”
  • Prerequisites: A PLC with HMI project (see HMI lifecycle) deployed to a started runtime (see Runtime control overview).
  • Required role/permission: A role that can open the visualization; operating controls that write values requires edit/operator rights — a Viewer sees the live HMI but write actions may be blocked.
  • Settings that affect behavior:
    • Runtime must be running — the HMI shows live values only when bound to a started runtime serving the deployed build.
    • Resolution — the HMI view shown matches the resolution(s) configured in the project.
    • Variable bindings — components reflect the project/global variables they are bound to; unbound components show no live data.
    • Edge HMI updates — on edge devices, on-change update behavior affects how quickly values refresh (see Edge HMI on-change updates).

Steps

Section titled “Steps”
  1. Build the PLC with HMI project and deploy it to a runtime; start the runtime (see Runtime control overview).
  2. Open the project’s visualization at /portal/workspace/visualization/:id.
  3. Select the running runtime as the live source for the HMI.
  4. Observe live values updating; interact with operator controls to write values back to the runtime.

No captured steps yet. Run make regenerate-flows after a portal-e2e:docflow pipeline run produces docflow-output/hmi-runtime-overview.json.
