Woodward 5466-1145 CPU5200 Cyber Security Controller

​Overview

The Woodward 5466-1145 is a cyber-hardened CPU5200 main controller developed for the MicroNet Plus digital control platform. Designed for mission-critical rotating equipment, this controller combines deterministic real-time performance with an embedded cybersecurity framework suitable for regulated industrial environments.

This unit supports both simplex and fully redundant control architectures and is commonly deployed as the primary processor in turbine, engine, and compressor control systems where availability, safety, and secure communications are mandatory.

Controller Function and System Role

Within a MicroNet Plus control rack, the CPU5200 Cyber Security Unit operates as the central execution and coordination module. It manages control logic, I/O data processing, network communications, and system diagnostics.

In redundant configurations, the controller operates in parallel with a second CPU installed in the CPU2 slot, enabling fault-tolerant operation with automatic role arbitration and seamless switchover.

Cyber Security Architecture

The 5466-1145 variant is delivered with a licensed cyber-security feature set that aligns with modern critical-infrastructure protection standards.

Key security characteristics include:

Secure implementation of VxWorks RTOS 6.8 with hardened services
Encrypted communication using Secure Shell (SSH)
Role-based user authentication and password control mechanisms
Embedded firewall functions to restrict unauthorized access
Updated GAP security function blocks and protocol toolsets
Designed to support NERC CIP-aligned system deployments

This architecture ensures deterministic control performance without compromising security posture.
