Schneider Electric 140CPU67260 – Hot Standby Redundant Processor | Modicon Quantum Platform
Engineering Background: The Modicon Quantum series represents Schneider Electric’s flagship large-scale PLC platform, engineered for mission-critical process control in industries where unplanned downtime carries severe operational and safety consequences. The 140CPU67260 is the dedicated Hot Standby (HSBY) processor module within this platform, designed to operate in a primary/standby redundant pair configuration.
Product Positioning: The 140CPU67260 is specified by control engineers who require IEC 61511 / IEC 61508-aligned redundancy architectures in oil & gas, power generation, water treatment, and continuous manufacturing environments. It eliminates single-point-of-failure risk at the CPU level by enabling bumpless, automatic failover in under 10 ms.

Engineering Advantages
- Bumpless Failover: Primary-to-standby switchover completes within one PLC scan (<10 ms), ensuring zero process disruption and no output glitches.
- Fiber-Optic HSBY Link: Immune to electromagnetic interference; maintains synchronization integrity in electrically noisy industrial environments.
- Unified Programming Environment: Fully supported by EcoStruxure Control Expert (formerly Unity Pro), enabling seamless migration from legacy Quantum systems.
- Large Memory Footprint: 7 MB user memory accommodates complex process programs, data logging, and advanced function blocks without external memory expansion.
- Dual Network Connectivity: Simultaneous Modbus Plus and Modbus TCP/IP support enables integration with both legacy field devices and modern SCADA/HMI systems.
- Proven Platform Longevity: Modicon Quantum has 20+ years of installed base; spare parts and technical support remain widely available.
System Architecture & Signal Flow
In a Quantum HSBY configuration, two identical 140CPU67260 modules are installed in separate Quantum racks. The Primary CPU executes the control program and drives all outputs. The Standby CPU receives continuous state synchronization via the dedicated fiber-optic HSBY link, maintaining a mirror image of all data registers, I/O states, and program variables.
Upon detection of a primary CPU fault (hardware failure, watchdog timeout, or power loss), the standby module assumes control within one scan cycle. The HSBY link supports distances up to 15 m (140XCA71707) or 100 m (140XCA71714) between racks, enabling geographically separated redundant panels.
Typical HSBY System BOM includes: 2× 140CPU67260 | 2× Quantum backplane | 1× HSBY fiber cable | 2× Power supply modules | Shared I/O via RIO or distributed I/O drops.
Sourcing & Quality Verification

Technical FAQ
Q: Can the 140CPU67260 replace a 140CPU67160 in an existing system?
A: The 140CPU67260 is the successor model with expanded memory. It is backward-compatible with existing Quantum backplanes and I/O modules, but firmware and Unity Pro project migration should be validated before live deployment.
Q: Is a fiber-optic cable included with the module?
A: No. The HSBY fiber cable (140XCA71707 for 15 m or 140XCA71714 for 100 m) must be ordered separately. Please specify your inter-rack distance when requesting a quote.
Q: What programming software version is required?
A: Unity Pro v4.0 or later (now EcoStruxure Control Expert) is required. The HSBY configuration wizard is included in the standard software package.
Q: Can this module be used in a non-redundant (simplex) configuration?
A: Yes. The 140CPU67260 can operate as a standard (non-HSBY) processor, though the 140CPU67160 is the more cost-effective choice for simplex applications.
Q: What is the typical lead time for new OEM units?
A: Stock availability varies. Surplus and refurbished units typically ship within 3–7 business days. New OEM units may require 4–12 weeks depending on Schneider Electric’s current production schedule. Contact us for real-time availability.
