Description
- The Woodward 5462-758 is a specialized communication and I/O expansion module designed for the MicroNet and MicroNet TMR (Triple Modular Redundant) control systems. This module serves as a LinkNet controller, facilitating the interface between the high-speed MicroNet backplane and distributed LinkNet I/O nodes. It allows the central control system to communicate with remote digital and analog I/O points over a robust, serial network, significantly reducing field wiring costs and complexity for large-scale turbine and engine control applications.

Application Fields
This module is essential for expansive industrial control layouts where I/O points are distributed across a large physical area, such as:
- Power plant balance-of-plant (BOP) monitoring and control.
- Distributed fuel system management for multi-cylinder large engines.
- Remote monitoring of auxiliary turbine systems (lube oil, cooling water).
- Integration of non-critical field sensors into a centralized MicroNet architecture.
Usage Instructions
The Woodward 5462-758 must be seated firmly into a designated I/O slot of a MicroNet or MicroNet TMR chassis. Once the hardware is installed and the captive screws are tightened, the LinkNet twisted-pair network cable is connected to the front-panel terminal. During system configuration using Woodward’s GAP (Graphical Application Programmer) software, the user must define the LinkNet network parameters and map the remote I/O addresses to the internal control variables. Ensure that the LinkNet network is properly terminated with a 120-ohm resistor at the last node to prevent signal reflections and data corruption.
Frequently Asked Questions (Q&A)
Q: What is the maximum distance for a LinkNet network using the 5462-758? A: The LinkNet network can typically extend up to 150 meters (approximately 500 feet) from the controller module to the furthest node, depending on the cable quality and environmental noise levels.
Q: Can this module be used for both Analog and Discrete LinkNet nodes? A: Yes, the 5462-758 is designed to manage the communication for the entire LinkNet string, which can include a mix of discrete input/output modules and analog input/output modules.
Q: What do the “Status” and “Link” LEDs on the front panel indicate? A: The “Status” LED confirms the module has passed its internal power-on self-test, while the “Link” (or Network) LED flashes to indicate active data transmission between the MicroNet CPU and the remote LinkNet nodes.
