- Coordinates communication between all system modules
- Manages turbine and compressor control loops
- Handles diagnostics, fault detection, and system monitoring
- Ensures deterministic cycle timing for industrial automation
It continuously runs a control loop:
Input acquisition → logic execution → output update
