Main functions and features
Core Communication Gateway Function
Protocol conversion hub:
CAN bus interface: usually connects to the internal CAN network of the device (such as SAE J1939), and communicates with the engine governor (such as 9907 series), engine ECU, etc.
Serial Communication Interface (RS-232/RS-485): Supports protocols such as Modbus RTU and is used to connect generator controllers, smart meters, or other serial devices.
Ethernet interface: Provides 10/100M Ethernet ports and supports Modbus TCP/IP protocol. This is the key to achieving remote access and integration with factory level SCADA/DCS systems.
Data aggregation and forwarding: It aggregates data from different buses (CAN, RS-485) and protocols (J1939, Modbus RTU), maps them uniformly to Modbus TCP registers on the Ethernet, and provides "one-stop" access for the upper computer.
Remote access and configuration channel
Through Ethernet, technicians can use Woodward Toolkit from anywhere in the world with network connectivity ™ The software allows remote login to the 5501-467 module to diagnose, configure, and debug all Woodward controllers connected to it (such as governors, EasyGen main controllers, etc.), greatly facilitating engineering and maintenance work.
Additional digital and analog I/O
The module itself typically integrates programmable digital inputs (DI) and relay outputs (DO).
Digital input: can be used to receive additional status signals (such as oil pressure switch, water temperature switch, remote start stop command, etc.).
Relay output: can be used to drive additional alarm indicator lights, external alarms, or perform simple control logic (such as starting a backup pump).
These I/O points can be logically programmed through Toolkit software to implement custom interlocking or protection functions, thereby expanding the capabilities of the main controller.
Easy to integrate and indicate status
Adopting DIN rail installation, compact design.
Provide clear LED status indicators for displaying power, network activity, communication status, etc.
Typical application scenarios
5501-467 is widely used in generator sets that require complex monitoring, remote management, and system integration, especially:
Remote monitoring of power stations: For backup power sources in remote areas such as oil and gas fields, mines, and wind farms, unmanned operation and remote fault diagnosis can be achieved.
Multi unit parallel system: As the "communication agent" for each generator unit, standardize the unit data and upload it to the parallel control cabinet or power station management system.
Factory backup power integration: seamlessly integrate diesel or gas generator sets into the factory's distributed control system or building management system.
In situations where custom I/O logic is required: when the standard controller's I/O points are insufficient, it is used to supplement and implement specific control logic.
Product advantages
Breaking the information silo: one-stop solution for communication integration of multiple heterogeneous devices.
Powerful remote capability: significantly reduces on-site service frequency and cost, and improves response speed.
Flexible configuration: It is both a communication gateway and a programmable logic and I/O expansion unit.
Improve system reliability: achieve centralized monitoring and early warning through the network, and enable remote preventive maintenance.
Important supporting facilities and precautions
Core software: Woodward Toolkit must be used ™ Configure, program, and diagnose it using software.
Cybersecurity: This is a crucial aspect. When the control system of the generator set is connected to Ethernet, strict network security measures must be taken, such as setting up firewalls, using VPN, changing default passwords, and dividing independent subnets, to prevent network attacks.
Professional requirements: The configuration and programming require a professional engineer with both generator set control knowledge and basic network knowledge.
