ProcessAutomation Integration Patterns

This guide covers model integration patterns for multi-area systems, optimizers, and digital twins.

Multi-Area Addressing (ProcessModel)

Use area-qualified addresses:

• Separation::HP Sep.pressure
• Compression::Main Compressor.outletPressure

Best practices:

• Discover areas via getAreaList()
• Discover unit names per area via getUnitList(area)
• Avoid hardcoding area labels in shared libraries

Optimizer Integration

Typical loop:

1. Select INPUT variables from typed catalogs.
2. Apply candidate values.
3. Run the process model.
4. Read OUTPUT variables for objectives/constraints.

Use safe accessors during early-stage model evolution where naming changes are frequent.

Digital Twin Integration

Recommended service pattern:

• Poll telemetry-aligned OUTPUT variables on a fixed cadence.
• Apply supervisory setpoints to validated INPUT addresses.
• Track correction and failure rates from diagnostics for governance.

Pair automation access with lifecycle snapshots for reproducible operational states.
