CTC SMART TECHFrom equipment signals
to maintenance action.
A design case study based on the Industrial IoT and CPSmart profile: monitoring measurement points, verifying alerts, assigning maintenance and closing the loop.
CTC SMART TECHEvery step has an input.
Every decision has a basis.
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.
CTC SMART TECHFrom existing sources
to proposed design.
IoT/CPSmart capability documentation exists; the dashboards, assistant and apps in this kit are design prototypes not connected to real equipment.

that needs handling.
01
Review alerts and measurement-point quality.
02
Acknowledge receipt during the shift.
03
Forward the inspection request to maintenance.

CTC SMART TECHFocus on the work
that needs handling.
01
Receive the assigned work order.
02
Confirm the inspection per the on-site procedure.
03
Record the result and hand over for manager review.
CTC SMART TECHPlant manager

that needs handling.
01
Track handling status and owners.
02
Check maintenance results before closing an alert.
03
Summarise causes and improvements.
CTC SMART TECHRole-based apps.
Shared business data.
Experience
Admin workspace, mobile apps and assistant access the same record code.
Platform
Permissioned APIs, business services and change logs.
Data
Versioned sources, source-system integration and sync.
CTC SMART TECHCompare sources
before concluding.
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.
CTC SMART TECHApproval tied to
the accountable person.
Operator
Acknowledges and reports state; cannot change thresholds or control machines.
Maintenance technician
Assigned work only. Cannot close alerts before approval.
Plant manager
Approves state within scope; OT control changes need a separate procedure.
CTC SMART TECHTry in a small scope.
Measure before scaling.
01
Survey measurement points, protocols and the OT/IT boundary.
02
Connect read-only; check timestamps, missing data and buffering.
03
Run trial alerts; cross-check with operations/maintenance.
04
Accept the confirm–handle–close loop and recovery capability.
CTC SMART TECHProve it with
scenarios and data.
01
Alerts store source, time and measurement-point quality.
02
No closing without an inspection result.
03
Delayed / disconnected data shows the correct state.
04
The monitoring flow never generates control commands.
CTC SMART TECHDefine the priority
problem together.
