The following diagram shows how the families used in SIS Management are related to one another.
Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of the each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.
All SIL Analyses begin with an SIL Analysis record. Each SIL Analysis can be linked to:
One Equipment or Functional Location record.
One or more Human Resource records.
One or more Reference Document records.
One or more Instrumented Function records.
One or more Logic Solver records.
Each Logic Solver is linked to:
One or more Instrumented Function records.
One or more SIS Proof Test records.
One or more SIS Proof Test Template records.
Each Instrumented Function is linked to:
One Equipment or Functional Location record.
One or more Protective Instrument Loop records.
One or more Inspection Task records.
One Risk Assessment record.
One LOPA Assessment record.
One Process Hazards Analysis (PHA) Assessment record.
One or more External Assessment records.
One or more SIS Proof Test records.
One or more SIS Proof Test Template records.
To simplify the data model images, the following families are not included:
Risk Assessment Recommendation: Within the SIS Management data model, the Risk Assessment Recommendation family participates as the successor in the Has Recommendations relationship definition with the following families:
Instrumented Function
Protective Instrument Loop
SIS Proof Test
SIS Proof Test Template
Hazards Analysis: The Hazards Analysis family participates as the successor in the Has HAZOP Reference relationship definition with the SIL Analysis and Instrumented Function families.
