Functional Description

5463-140 is a Master CPU developed by Woodward. It is a part of MicroNet Plus control system. It is designed to provide seamless integration and operation of control systems with advanced redundancy features, ensuring continuous and reliable performance in high-availability applications. The MicroNet Plus system allows for redundant master/standby configurations, enabling higher system availability and minimizing the risk of downtime. In this configuration, one Master CPU actively manages the control system, while a standby CPU is ready to take over in case of failure.

Features

• Both CPUs continuously synchronize their memory, ensuring that both are operating with identical information at all times, even when the system is running multiple rate groups.
• If the master CPU fails, control is transferred to the standby CPU in less than 1 millisecond, ensuring no disruption to the prime mover or system operations. After rectifying the fault, the control can be transferred back to the master CPU without interrupting the operation.
• In the event of a CPU fault or transfer of control from master to standby, the system announces the transfer through communication links, ensuring that operators are immediately aware of the change and can take necessary actions if required.
• The MicroNet Plus Master CPU incorporates an SNTP version 4-compliant time server, enabling precise time synchronization with external time sources, accurate to less than 1 millisecond. This is particularly critical for applications requiring high-precision timing, such as sequencing and process control.
• The system allows time stamping of events with 1-millisecond resolution for Discrete I/O and 5-millisecond resolution for Analog I/O and software process variables. This feature is important for accurate logging and tracking of system activities, which helps in troubleshooting, auditing, and historical analysis.

Benefits

• Redundant operation ensures that system control continues even if the master CPU experiences a fault, providing continuous uptime for critical applications.
• The automatic failover to the standby CPU ensures there is no impact on prime mover operation, making it ideal for high-availability environments such as power plants and systems.
• The built-in time server and precise time-stamping capabilities provide accurate sequencing of events and synchronization with external time sources, making it essential for processes that rely on exact timing.
• With rapid failover mechanisms and communication link notifications, any faults are immediately detected and addressed, ensuring smooth system operations.
