Function and Working Principle
The 5466-352 acts as the main controller of the MicroNet NetCon system.
Its core functions include:
- Executing real-time control algorithms
- Managing communication between CPU and I/O modules
- Handling system-level coordination and sequencing
- Processing analog and digital field data
- Supporting deterministic industrial control operations
- Monitoring system health through watchdog logic
In the event of a fault, the module triggers an IOLOCK state, ensuring all outputs are safely de-energized to protect equipment and personnel.
Role in Industrial Control Systems
Within legacy MicroNet architectures, the 5466-352 serves as the central intelligence unit, responsible for:
- Coordinating all field I/O operations
- Managing turbine or compressor control loops
- Executing protection and shutdown logic
- Supporting communication with expansion racks
- Ensuring deterministic response in real-time systems
- Maintaining safe system behavior during faults
It is typically used in high-reliability industrial environments where continuous operation is critical.
Industrial Applications
The Woodward 5466-352 is widely used in:
- Gas turbine control systems
- Steam turbine governing systems
- Compressor control units
