Performance Optimization​

For better performance:

  • Limit the displayed period (avoid very long periods)
  • System automatically samples if too many points
  • Maximum 5000 points displayed per query

Use Cases​

Temperature Monitoring​

View temperature evolution over 24h to detect anomalies.

Consumption Analysis​

Track output activation cycles to optimize consumption.

Fault Diagnosis​

Identify moments when a sensor had abnormal behavior.

Analysis Use Cases

Troubleshooting​

No data displayed​

  • Verify history is enabled for this I/O
  • Check that the selected period contains data
  • Ensure equipment was online during this period

Incomplete data​

  • Equipment may have been offline
  • Check network connection
  • Data is only recorded when equipment communicates
Tip

Enable history only on I/O you want to analyze to optimize storage.
