The Schneider Electric 140CPU67260 is a high-tier processor engineered for mission-critical redundancy within the Modicon Quantum platform. Featuring integrated Hot Standby (HSBY) capability and multimode fiber Ethernet, it enables two identical CPUs to operate in synchronized parallel. In the event of a failure, the standby controller takes over within milliseconds, ensuring uninterrupted process control and maximum system availability.

Seamless Failover Execution
Hot Standby synchronization ensures both CPUs mirror each scan cycle. If the primary fails, the standby instantly assumes control without interrupting field operations.
Fiber Optic Interference Immunity
Multimode fiber communication eliminates susceptibility to EMI and RFI, making it ideal for electrically noisy industrial environments.
High-Speed Data Synchronization
A 266 MHz processor combined with ample memory supports complex control logic, large programs, and precise real-time synchronization.
Long-Distance Redundancy
Fiber optic links allow greater physical separation between primary and standby systems, supporting geographically distributed redundancy strategies.
Is this module brand new?
Yes, it is supplied as 100% brand new original Schneider Electric equipment in factory-sealed packaging.
What type of synchronization link is required?
The processor uses multimode fiber optic cables. Proper fiber type and connector compatibility must be ensured for reliable operation.
Can different CPU models be paired in Hot Standby?
No, Hot Standby requires two identical 140CPU67260 processors with matching firmware versions.
What happens to Ethernet communication during switchover?
The system performs automatic IP address transfer (IP swapping), allowing SCADA and HMI systems to maintain continuous communication without reconfiguration.
