Schneider 140CPU67060 Modicon Quantum HSBY CPU

Product Description

The Schneider Electric Modicon Quantum 140CPU67060 is a high-availability Unity Hot Standby (HSBY) processor engineered for mission-critical automation systems requiring continuous operation and redundancy. Designed for dual-CPU architectures, it enables seamless switchover between primary and standby controllers, minimizing downtime in process control environments.

This processor integrates multimode fiber-optic Ethernet for high-speed synchronization between redundant PLCs and supports large-scale distributed I/O systems across multiple industrial networks.

Key Features and Capabilities

• Hot Standby redundancy with automatic CPU synchronization
• Multimode fiber-optic Ethernet link (up to 4 km) for primary/secondary PLC interconnection
• High processing performance at 266 MHz
• Extensive communication protocol support including Modbus, Modbus Plus, Ethernet TCP/IP, and Profibus DP
• Scalable architecture for large distributed I/O systems
• Designed exclusively for remote and distributed I/O (local I/O not supported in HSBY mode)

FAQ

Q: What is the main advantage of this processor compared to standard CPUs? A: The key advantage is its Hot Standby capability, allowing redundant CPU operation with automatic failover, ensuring continuous system availability.

Q: Can local I/O modules be used with this processor? A: No, local I/O is not supported in Hot Standby mode. Only distributed and remote I/O configurations are allowed.

Q: What type of redundancy link is used between CPUs? A: A multimode fiber-optic Ethernet connection (MT-RJ) is used for high-speed synchronization between primary and standby processors.
