Schneider Modicon Quantum 140CPU67260 Unity Hot Standby Processor

Product Overview

The Schneider Electric 140CPU67260 stands as the pinnacle of high-availability control within the Modicon Quantum platform. Specifically engineered for Hot Standby (HSBY) applications, this Unity-based processor synchronizes primary and secondary controllers via an integrated multimode fiber optic link. It manages massive I/O architectures across Ethernet, Modbus Plus, and Profibus DP networks, ensuring seamless switchover and zero data loss during a hardware failure. We provide this processor as 100% Brand New and Original, ready to secure your mission-critical infrastructure against unplanned downtime.

Technical Specifications

The 140CPU67260 combines a high-speed 266 MHz clock with specialized hardware for rapid redundancy synchronization.

Engineering Advantages

• Instantaneous Redundancy Sync: The integrated multimode fiber port facilitates high-speed data mirroring between the primary and standby CPUs. This dedicated link eliminates the lag associated with external sync modules, providing a 4 km reach for geographically separated control rooms.

• Massive I/O Scalability: The 140CPU67260 handles an "Unlimited" number of discrete and analog I/O points via Ethernet Remote I/O drops. This allows engineers to consolidate massive plant-wide processes into a single redundant pair.

• Deterministic Fault Recovery: During a primary processor fault, the system executes a bumpless transfer to the standby unit. This prevents process upsets in sensitive environments like chemical reactors, oil refineries, or water treatment plants.

• Multimodal Communication Hub: This CPU supports up to six optional modules, including Profibus DP and Ethernet TCP/IP. This versatility enables the Quantum system to act as a central data router, bridging legacy fieldbus protocols with modern enterprise-level Ethernet architectures.

• Enhanced Memory Management: A dedicated key switch controls the memory port, preventing unauthorized program changes. The 3072 KB of onboard RAM provides ample space for complex Unity Pro logic without requiring immediate memory expansion.

FAQs

• Does the 140CPU67260 support local I/O modules?

  In a Hot Standby configuration, the system forbids the use of local I/O in the CPU rack to ensure deterministic performance. All I/O must reside in Remote (RIO) or Distributed (DIO) drops.

• What type of fiber cable is required for the HSBY link?

  This model utilizes multimode fiber with an MT-RJ connector. For distances up to 4 km, use 62.5/125 $\mu m$ or 50/125 $\mu m$ multimode fiber.

• Can I use this processor with old Concept software?

  No. The 140CPU67260 is a Unity processor. It requires EcoStruxure Control Expert (formerly Unity Pro) for configuration and logic development.

• What is the significance of the 2760 mA bus current requirement?

  This processor consumes significant power from the backplane. You must ensure your Quantum power supply (e.g., 140CPS11420) provides sufficient amperage, especially when installing optional communication modules alongside the CPU.
