Class IntegratedSafetySystemWithLogicExample

java.lang.Object

neqsim.process.util.example.IntegratedSafetySystemWithLogicExample

public class IntegratedSafetySystemWithLogicExample
extends Object

Advanced example demonstrating integrated safety systems using the NeqSim process logic framework and scenario simulation capabilities.

This example showcases:

• Process Logic Framework with ESD Logic
• Automated Safety Instrumented Functions (SIF) with configurable voting
• Multi-scenario simulation with ProcessSafetyScenario
• Transient simulations with process logic execution
• Custom logic actions and conditions

Safety layers implemented:

• SIL-3: HIPPS with 2oo2 voting logic
• SIL-2: ESD with automatic and manual triggers
• SIL-1: Process alarms and operator intervention
• PSV: Final mechanical protection

Version:

1.0
