Illustrative application scenario
Assumptions
Assume the PLC exposes running and fault signals, while operators confirm planned stops and reason codes.
Data flow
PLC → collector → state transitions → downtime intervals → reason confirmation → report.
Illustrative workflow
Communication loss becomes an unknown interval. Delayed records are processed by event time. Operator corrections retain an audit trail.
Limits and field conditions
This is an illustrative scenario, not a completed customer project or a performance commitment. Hardware, connectivity, permissions and physical safety conditions must be validated through discovery and field tests.
Questions for discovery
- Are technical documents for the data sources available?
- What delay is acceptable for current data?
- How will outages and sensor faults be detected?
- Which role responds to an alarm?
- What retention and reporting requirements apply?
