Alarm Appears on SCADA but Nobody Gets Notified? Trace the Pipeline
An active alarm and a delivered notification are separate outcomes. If the alarm appears locally but no one receives it, trace event routing, roster selection, and delivery status. Do not test by repeatedly creating real production faults.
Notification features depend on installed modules and configuration.
What is happening?
Notification systems connect alarm events to profiles, pipelines, recipients, and schedules. Filtering, delays, acknowledgments, and escalation rules can intentionally affect delivery. Product test tools help distinguish configuration problems from transport failures.
Check these five things
-
Identify the alarm event and configured notification route.
-
Check enabled profiles, pipeline selection, and event filters.
-
Verify the intended roster and schedule for the event time.
-
Use approved test recipients and supported notification tests.
-
Review delivery diagnostics and expected escalation behavior.
Worked example
A teaching alarm activates correctly but selects a roster with nobody on duty at that hour. The mail server is healthy, yet no recipient is chosen. A transport-only test would pass while the operational notification path remains incomplete.
Quick diagnostic reference
| Stage | Evidence |
|---|---|
| Alarm event | Created as expected |
| Pipeline | Event accepted |
| Roster | Recipient selected |
| Delivery | Result recorded |
The mistake to avoid
A successful test email from a settings page does not prove that a real alarm reaches the right roster and escalation path. Validate the end-to-end route with controlled events.
How to verify the fix
Record event, recipient selection, delivery outcome, and escalation timing for an approved test. Make failure diagnostics visible so notification outages do not remain silent.
Field-work boundary: These are educational diagnostic guides. Use the exact equipment manuals and approved site procedures. Electrical testing and machinery changes belong to qualified, authorized personnel; control hazardous energy and validate affected functions before release.
