Is CCU 2 a backup controller that ensures failure of CCU 1 has no significant effect on the IRMS?

CCU 2 serves as a backup controller for CCU 1, ensuring that if there is a failure in CCU 1, the operation of the Integrated Risk Management System (IRMS) remains largely unaffected. This redundancy is crucial for maintaining system reliability and safety. The design of having a backup controller allows for minimal disruption to the IRMS functionality, effectively managing risk and ensuring that critical operations can continue even in the event of a failure. The redundancy built into the system recognizes the importance of uninterrupted performance and demonstrates a robust approach to system design, allowing for contingency plans in case of primary controller failure.
