Product Overview
The Woodward 5466-1035 is a MicroNet Plus CPU5200 processor module used as the central processing unit in Woodward MicroNet digital control systems. It is built around a Motorola PowerPC MPC5200 processor and is designed to execute real-time control applications for turbine and other industrial machinery. The module supports simplex or redundant operation and uses a standard 14-slot VME chassis architecture. Available documentation identifies 64 MB flash memory, 128 MB RAM, dual CAN capability, Ethernet connectivity, and a real-time clock as part of the CPU5200 platform. Woodward classifies this part number as a non-preferred MicroNet Plus CPU, but it remains relevant for repair and spare-parts applications.

Installation and Maintenance — 5466-1035
Before replacement, record the CPU revision, Coder version, firmware, application configuration, chassis position, Ethernet settings, and CAN configuration. Preserve the existing application before removing the processor.
Use ESD protection and follow the MicroNet shutdown procedure. Inspect the VME backplane connector and module seating surfaces before installation. After startup, verify CPU diagnostics, application execution, network communication, and redundant-controller status where applicable.
Personally, I would check the hardware revision before ordering this spare. Woodward states that 5466-1035 must be revision F or later for certain Cyber Secure upgrade paths, while the 5466-1035 itself does not provide the security features of newer CPU generations.
Product Warranty — 5466-1035
Warranty coverage depends on supplier, equipment condition, and purchase agreement. For new-old-stock, surplus, or refurbished units, verify the exact hardware revision, firmware/Coder compatibility, serial number, functional-test results, and warranty period before purchase.
The Woodward 5466-1035 remains a relevant maintenance spare for installed MicroNet Plus systems, but it should not be treated as the preferred choice for a new cybersecurity-sensitive installation. Woodward and GE recommend newer CPU platforms for systems requiring improved security capabilities.
