8280-500 Woodward Processor module

Product  Description：

A WOODWARD processor module, often referred to as a CPU (Central Processing Unit) module, functions as the brain of a control system like the MicroNet Plus or MicroNet TMR platforms. It contains a high-speed microprocessor, memory (RAM and flash), and various communication interfaces. Its primary role is to run the control application, process sensor inputs, calculate control outputs, manage communication with other modules and external systems, and perform diagnostics to maintain system integrity and reliability. These modules are designed to offer robust computing power and advanced functionality for critical control tasks.

Key Functions

• Program Execution: Runs user-defined control algorithms (often developed in Woodward's Graphical Application Program - GAP).

• Data Processing: Manages and processes real-time data from various sensors and inputs.

• Control Output Generation: Calculates and generates precise control signals for actuators and other output devices.

• Communication Management: Facilitates data exchange with I/O modules, communication modules, HMIs, DCS, and other network devices.

• System Diagnostics: Monitors the health of the control system and connected equipment, providing fault detection and alarm generation.

• Redundancy Management: In redundant systems (like TMR - Triple Modular Redundancy), the processor modules manage voting and synchronization to ensure uninterrupted operation.

Product Parameters (Typical)

Parameters vary significantly depending on the specific model and series (e.g., MicroNet Plus, MicroNet TMR, NetCon). Here are some typical ranges and examples:

• Processor: High-speed, often embedded microprocessors (e.g., Intel Atom, MPC5200 for older modules).

• Clock Speed: Can range from hundreds of MHz to over 1 GHz for newer modules.

• Memory:

  • RAM: Typically tens to hundreds of MB (e.g., 128 MB DDR RAM).

  • Flash Memory: Tens to hundreds of MB (e.g., 64 MB flash).

• Communication Interfaces:

  • Ethernet: Often multiple ports for real-time control networks and general-purpose communication (e.g., two general-purpose, one Real Time Network port).

  • Serial Ports: RS-232, RS-485 for various protocols.

  • CAN Ports: For Controller Area Network communication.

  • Service Port: Dedicated for configuration and diagnostics.

  • Fieldbus Standards: Support for protocols like Modbus, PROFIBUS, etc.

• Power Consumption: Application-specific, but generally low to moderate (e.g., 6-11 Watts).

• Operating Voltage: Typically 24 VDC or 125 VDC nominal, with a wide acceptable range.

• Operating Temperature: Wide industrial-grade range (e.g., -40°C to +85°C, or 0°C to +55°C depending on specific series and environment).

• Storage Temperature: Often wider than operating temperature (e.g., -40°C to +120°C).

• Humidity: Up to 95% non-condensing.

• Mounting Type: Typically rack-mounted within a dedicated chassis.

• Certifications: Often meet various industrial standards (e.g., Lloyd's Register for humidity, MIL-STD for vibration/shock, Class I, Div 2 for hazardous areas).

Product Advantages

• High Performance and Accuracy: Engineered for rapid data processing and precise control, crucial for demanding applications like turbine speed and fuel control.

• Exceptional Reliability and Uptime: Features like redundant configurations (e.g., dual CPUs in simplex or TMR systems) and robust hardware ensure continuous operation and minimize downtime.

• Flexibility and Scalability: Modular design allows for customization and expansion to meet diverse application requirements, from simple to complex systems with extensive I/O.

• Comprehensive Communication: Support for a wide array of industrial communication protocols ensures seamless integration with plant-wide control systems (DCS, SCADA).

• Advanced Diagnostics: Built-in diagnostic and monitoring capabilities provide real-time performance insights, facilitate fault detection, and enable proactive maintenance.

• Robustness: Designed to withstand harsh industrial environments, including wide temperature ranges, high humidity, and vibration.

• Long-Term Support: Woodward's commitment to long-term product support and service is a significant advantage for critical infrastructure.

Precautions

• Electrostatic Discharge (ESD): WOODWARD processor modules contain sensitive electronic components. Always follow proper ESD precautions when handling the modules, including wearing anti-static wrist straps and avoiding contact with conductive surfaces.

• Compatibility: Ensure the processor module is compatible with the specific chassis, I/O modules, and software versions of your Woodward control system. Mismatching components can lead to operational issues or damage.

• Power Supply: Verify that the system's power supply meets the module's voltage and current requirements. Stable and clean power is essential for reliable operation.

• Configuration: Proper software configuration using Woodward's proprietary tools (like GAP) is critical. Incorrect programming can lead to improper control, system instability, or even damage to the controlled machinery.

• Environmental Conditions: Operate the module within its specified temperature, humidity, and vibration limits. Exceeding these limits can compromise performance and reduce lifespan.

• Wiring Integrity: Ensure all wiring to and from the module is correctly installed, shielded where necessary, and terminated securely to prevent electrical noise and ensure signal integrity.

• Redundancy Considerations: In redundant systems, understand the specific requirements for module placement and synchronization to ensure true fault tolerance.

Product Applications

WOODWARD processor modules are at the heart of control systems for mission-critical rotating machinery and power management across various heavy industries:

• Power Generation:

  • Gas Turbines: Speed control, fuel management (including DLE/DLN systems), combustion control, anti-surge control, and overall plant sequencing.

  • Steam Turbines: Speed and load control, extraction/admission control, and generator synchronization.

  • Hydro Turbines: Water level and flow control, synchronization, and power output regulation.

  • Reciprocating Engines (Diesel/Gas): Speed control, fuel injection, ignition timing, and load sharing.

  • Generators: Synchronization, load sharing, and power export/import control.

• Oil and Gas:

  • Compressor Control: Anti-surge control, performance control, and load management for large industrial compressors.

  • Pumps: Control of critical pumps in pipelines and processing facilities.

  • Pipelines: Compressor station control, flow regulation, and safety systems.

• Process Industries:

  • Control of industrial furnaces, boilers, and other process equipment requiring precise control of speed, temperature, and flow.

• Marine Transportation:

  • Engine and propulsion control systems on large vessels.
