Class ProcessLogicAlarmIntegratedExample

java.lang.Object
neqsim.process.util.example.ProcessLogicAlarmIntegratedExample
public class ProcessLogicAlarmIntegratedExample extends Object
Complete integrated example demonstrating alarm-triggered process logic.

This example demonstrates the full integration of:

  • Multi-level alarm configuration (LOLO, LO, HI, HIHI)
  • ProcessAlarmManager for centralized alarm coordination
  • Alarms triggering automatic process control actions
  • Alarms triggering ESD sequences
  • Alarm acknowledgement and clearance workflows
  • HIPPS Logic with alarm-based activation
  • Startup Logic with alarm permissives
  • ProcessScenarioRunner for automated testing

Layered safety architecture with alarm integration:

  • Layer 1 (Alarms): HI/LO alarms trigger operator actions or control adjustments
  • Layer 2 (Alarms + Control): HIHI/LOLO alarms trigger automatic control responses
  • Layer 3 (SIL-2): HIPPS provides independent fast-acting pressure protection
  • Layer 4 (SIL-2): ESD system provides emergency shutdown
  • Layer 5 (Mechanical): PSV provides final mechanical protection
