Woodward 5466-352 NetCon CPU-040 for MicroNet Systems

Technical Specifications

Processor and Memory Architecture

The 5466-352 uses a 68030 microprocessor. This processor connects to the VME bus through dual-ported RAM. Four network communications processors each have their own dual-port RAM link. Therefore, data exchange is fast and efficient.

Service Panel Communication

System operators can communicate with the Woodward 5466-352 using the Service panel. This works when the CPU module runs in a stand-alone MicroNet system. The Service panel provides direct access for diagnostics and configuration.

Reset Methods for Different Systems

For simplex CPU systems, toggle the CPU switch to the reset position on the 5466-352. For MicroNet Plus 5200 CPU or CPU P1020 systems, use AppManager to stop the application. Never use the CPU reset button on these systems. Otherwise, the application will restart automatically in about two minutes.

Fail-Safe Features

Watchdog Logic and IOLOCK State

The 5466-352 includes watchdog logic for safety. When the CPU fails, this logic forces the module into an IOLOCK state. In IOLOCK mode, all output circuits and signals de-energize completely.

System-Wide IOLOCK Propagation

Furthermore, an IOLOCK signal broadcasts to all modules and expansion racks. Every connected module then enters IOLOCK state. This ensures the entire system goes to a safe condition during a CPU failure.

Additional Protective Features

The Woodward 5466-352 also includes manual reset capability. LED indicators show operational status at a glance. Panel mount design simplifies installation in standard cabinets.

Functional Role in Control Systems

This CPU module serves as the brain of a MicroNet simplex system. It executes control logic for turbines, generators, or industrial processes. The 5466-352 works with I/O modules, transceivers, and actuator drivers. Fiber optic coder interfaces may also connect to this processor. Additionally, it supports the 2.08 control system environment.

Mechanical and Environmental Parameters

The 5466-352 follows the 9900 Series rugged design standards. Operating temperature ranges from 0°C to +60°C. Humidity tolerance is 5% to 95% non-condensing. The module resists vibration found in turbine control rooms. Gross weight is 2.3 kg for easy handling.

Frequently Asked Questions (FAQ)

1. Can the 5466-352 be used in a redundant CPU system?
No, this CPU module is designed only for simplex (non-redundant) MicroNet systems.

2. What happens during an IOLOCK event on the Woodward 5466-352?
All output circuits and signals de-energize immediately. Additionally, an IOLOCK signal disables all connected modules and expansion racks.

3. How do I restart the application after a CPU reset?
On simplex systems, toggle the CPU switch from reset to run. On MicroNet Plus systems, use AppManager. The 5466-352 will not auto-start the application.

4. How many network communications processors does this module support?
The 5466-352 communicates with four separate network communications processors. Each uses a dedicated dual-port RAM interface.

5. Can I hot-swap the 5466-352 while the system is powered?
No, always power down the chassis before installing or removing this CPU module. Hot-swapping may damage the module or the backplane.
