A design case study based on the Industrial IoT and CPSmart profile: monitoring measurement points, verifying alerts, assigning maintenance and closing the loop.

Evidence status

IoT/CPSmart capability documentation exists; the dashboards, assistant and apps in this kit are design prototypes not connected to real equipment.

Sample UIs use synthetic data. Existing DocAgent screenshots have record/partner/figure data redacted. No real customer or employee results are used for illustration.

Collect

Log timestamp, equipment, measurement point and signal quality.

Verify

Operations receives the alert and checks data reliability.

Assign

Create an inspection request for the right technician.

Maintain

Record the checklist, on-site result and evidence of work.

Close the loop

The manager checks the result before closing the alert.

Why does this measurement point need verification? Sourced simulated scenario; no LLM call.

02 / Role-based apps

Every role has a clear workflow.

The apps focus on frequent tasks. In production they share the APIs, file codes, permission policy and history of the business platform.

Module mapping & permission limits

RoleModuleScope
OperatorMonitoring → Alerts → Maintenance requestAcknowledges and reports state; cannot change thresholds or control machines.
Maintenance technicianWork order → Checklist → Inspection resultAssigned work only. Cannot close alerts before approval.
Plant managerDashboard → Maintenance → Close approval → Audit logApproves state within scope; OT control changes need a separate procedure.

The first role completes the checklist and submits evidence; the next role records an evidence-based result; the approver confirms or returns with a reason. The sample session logs every step.

Prototype boundary

No real sensor connection, no machine-operation instructions, no PLC/SCADA writes.

Sample state is stored in the same browser, separated per solution. There is no authentication, multi-user backend, cross-device sync, push or LLM connection. Those must be built and accepted before real operation.

Sources to compare, not automatic conclusions.

SENSOR-DEMO v1

Simulated point: 78 °C with an illustrative 75 °C threshold. Not a recommended threshold for real equipment.

WORK-DEMO v1

Sample work order; on-site verification follows the plant-approved maintenance procedure.

POLICY-DEMO-OT

The prototype only tracks state; no PLC/SCADA connection and no control commands.

The simulated 78 °C signal exceeds the 75 °C sample threshold. Timestamp, sensor quality and site conditions must be checked per plant procedure; there is not enough evidence to conclude a failure. No control command is sent.

DEMO sources are synthetic data for simulation. Real business documents must be collected with usage rights, versioned and quality-checked.

Pilot & acceptance roadmap

  1. Survey measurement points, protocols and the OT/IT boundary.
  2. Connect read-only; check timestamps, missing data and buffering.
  3. Run trial alerts; cross-check with operations/maintenance.
  4. Accept the confirm–handle–close loop and recovery capability.

Conditions to verify

  • Alerts store source, time and measurement-point quality.
  • No closing without an inspection result.
  • Delayed / disconnected data shows the correct state.
  • The monitoring flow never generates control commands.

Agree scope, baseline, sample size, confirming person and operating responsibility before the pilot. Demos do not replace acceptance results or performance commitments.
