Description
Product Overview
The Woodward 5466-1035 serves as the central processing unit in a compatible MicroNet Plus control system. Based on the Motorola MPC5200 PowerPC processor, it executes the configured real-time control application used to regulate machinery and coordinate control-system functions. Typical applications include turbine control, generator-related processes, and other installations requiring deterministic machine-control logic.
The module can be used in simplex or redundant configurations, depending on the installed chassis and system design. Redundancy is not achieved by the CPU alone: the companion processor, chassis arrangement, application configuration, and transfer behavior must all be compatible. The 5466-1035 also belongs to an earlier MicroNet Plus generation. Its documented coder compatibility is listed as versions 4.06 through 5.04, so matching the existing application’s version is a critical replacement check.
Lifecycle planning deserves equal attention. Woodward’s Product Change Notification 06960, Revision C, dated July 2024, lists the 5466-1035 as non-preferred, with inactivity projected for 2028. Woodward states that non-preferred modules remain available to support existing installations, subject to product status, while the notice identifies newer preferred CPU options for MicroNet Plus systems. The dates are estimates, not guarantees. Before purchasing a spare or planning a migration, confirm the installed CPU revision, supported coder, cybersecurity requirements, and any approved upgrade path.
Product Introduction
The Woodward 5466-1035 MicroNet Plus CPU5200 is a controller processor module intended for compatible legacy MicroNet Plus installations. It provides the processing platform for the control application and interfaces with the configured system hardware.
For replacement work, verify the full part number, hardware revision, application-coder version, communications requirements, and whether the existing installation operates in simplex or redundant mode. Do not assume a newer CPU is a drop-in replacement simply because it belongs to the CPU5200 family.

Frequently Asked Questions
Q1: What is the Woodward 5466-1035 used for?
It is the CPU5200 processor module for compatible MicroNet Plus digital control systems, executing the configured real-time control application.
Q2: Can it operate in a redundant controller system?
Yes, it is documented for simplex or redundant operation. The companion CPU, chassis positions, application, and system configuration must support the selected arrangement.
Q3: Which application-coder versions does it support?
Woodward’s lifecycle notice lists coder versions 4.06 through 5.04 for the 5466-1035. Confirm the exact installed version and compatibility before swapping processors.
Q4: Can it support an expansion chassis?
Published technical information indicates that the 5466-1035 lacks the RTN port required for expansion-chassis operation. Verify the chassis architecture and module revision before planning an expansion.
Q5: Is the 5466-1035 discontinued?
Woodward’s July 2024 notice listed it as non-preferred, with inactivity projected for 2028. The notice also says non-preferred modules remain supported for existing-system spares and repairs. Confirm current production and service status before procurement.
Q6: Can a newer MicroNet CPU replace it?
Potentially, but not based on model family alone. Coder compatibility, hardware revision, communication requirements, cybersecurity needs, and the complete control-system configuration must be reviewed first.
Q7: What should be checked when purchasing a used or refurbished CPU?
Request photographs of the nameplate and revision, confirmation of the processor model, evidence of functional testing, and details of any repair or firmware work. For a redundant or critical control system, verify the approved replacement procedure and backup or recovery plan before installation.
