Product Description
Woodward 5466-1045 and Woodward 5466-1141 are MicroNet CPU module variants that execute the control application and exchange data with the rack I/O and communication paths. They provide the processing point between configured field data and the control logic running in the MicroNet system.
In operation, Woodward 5466-1045 and Woodward 5466-1141 receive configured I/O data through the MicroNet architecture, run the loaded application and publish the resulting control state to the connected rack interfaces. Their CPU hardware also carries the application-security function associated with the installed MicroNet configuration.
The rack path for Woodward 5466-1045 and Woodward 5466-1141 runs from the MicroNet backplane into the CPU processing position, where the loaded application exchanges I/O and status data with the rack interfaces.

03 // PROCESSING ROLE
Secure CPU Processing
Woodward 5466-1045 and Woodward 5466-1141 provide the application-processing point between MicroNet I/O data and the configured control outputs.
Data coordination
Woodward 5466-1045 and Woodward 5466-1141 exchange the application data needed by the associated I/O and communication paths.
State publication
The processed control state is placed back onto the configured rack interfaces for downstream modules.
04 // APPLICATION SECURITY
Application Security
The CPU module belongs in the MicroNet rack at the processing position defined by the project configuration and application record.
Rack position
The CPU occupies the assigned processing location and relies on the MicroNet backplane for the rack data path.
Application image
The software image and security configuration must be associated with the exact Woodward 5466-1045 or Woodward 5466-1141 record.
Communication boundary
External communication is handled through the configured rack or CPU interface; it is not created by the CPU label alone.
05 // FIELD QUESTIONS
Product Q&A
Which application record should be used for Woodward 5466-1045 / 5466-1141?
Use the application and security record belonging to the complete installed CPU number. Woodward 5466-1045 and Woodward 5466-1141 should not be treated as the same image target merely because both are MicroNet CPUs.
Why does Woodward 5466-1045 / 5466-1141 run but not exchange I/O data?
Check the rack slot, backplane connection and loaded application mapping before changing field wiring. The CPU can execute locally while a mismatched rack or image prevents the expected I/O data path.
How should the secured status of Woodward 5466-1045 / 5466-1141 be verified?
Verify the exact CPU record and the application security state in the configuration environment. Do not infer security capability from the front label or from the other part number.
Can Woodward 5466-1045 / 5466-1141 share one replacement image?
Only use a shared image when the project record explicitly permits it and the security requirements match. The two part numbers identify different CPU records, so the image and configuration must be checked separately.
What should be checked after moving Woodward 5466-1045 / 5466-1141 to another rack slot?
Confirm the slot assignment, rack address and backplane data map, then check that the application still names the same CPU position. A physical move without a configuration update can break the data path.
How can an intermittent Woodward 5466-1045 / 5466-1141 communication fault be isolated?
Separate the test into CPU application status, backplane data and external communication. This sequence shows whether the fault begins in processing, rack exchange or the configured external interface.
