| Redundancy | Duplexed design |
The unit utilizes a VR5432 processor at 133 MHz to maintain deterministic execution of control algorithms and I/O data polling. The duplexed design ensures system availability by utilizing redundant hardware modules that synchronize memory and process states via the Vnet communication interface. To protect volatile memory contents during utility power loss, the module incorporates an integrated battery backup system. This ensures that control data and current process states are maintained, allowing for seamless recovery upon power restoration.
Q: Does the battery backup require periodic maintenance?
A: Yes, the integrated battery backup is a consumable component. Refer to the system maintenance manual for recommended replacement intervals to ensure data protection during potential power failures.
Q: Is the Vnet communication port capable of direct connection to non-Vnet devices?
A: The Vnet port is designed for the proprietary Yokogawa high-speed control network. Integration with non-Vnet devices typically requires dedicated gateway modules or communication interface cards.
