The need and approach
Monitor machine states, cycles and downtime alongside production context.
Machine state and network availability are separate signals. A lost connection does not mean production stopped. Downtime reasons are completed through operator confirmation and maintenance records.
Signals to monitor
Running, waiting, fault, cycle count and production count
Data flow
Field device → data collection → timestamped record → industry-specific view → responsible person’s assessment.
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?
Limits and field conditions
Shift and product changes are timestamped; cycle times for different products on the same machine are not assumed to be directly comparable.
