Schneider Electric 140CPU67160 Modicon Quantum Central Processing Unit

The Schneider Electric 140CPU67160 Unity Hot Standby Processor is a high-performance central processing unit engineered for the Modicon Quantum automation platform. Operating at a clock speed of 266 MHz, this processor features integrated Hot Standby capabilities with multimode Ethernet support, providing deterministic logic execution and bumpless controller redundancy for mission-critical industrial architectures.

Processing Architecture and Memory Configuration

The unit incorporates a 1024 kB internal program memory and 768 kB of data memory to manage complex application code and large-scale control routines. It supports optional PCMCIA memory card expansion up to 8 MB for extended data storage and program backup. The architecture is designed without an arithmetic coprocessor, focusing dedicated computing cycles on fast boolean execution, task scheduling, and real-time I/O management.

Hot Standby Redundancy and Communication

Built for high-availability systems, the processor coordinates with a secondary peer unit via a dedicated high-speed fiber optic synchronization link to ensure seamless switchover during primary controller faults. Onboard communication ports include an integrated multimode Ethernet 100BASE-FX Hot Standby port, a Modbus RS-232 serial interface, a Modbus Plus network port, and a dedicated USB port for programming and diagnostics.

Parameter Specification

Installation Guidelines

Install the processor module into the designated primary CPU slot of a Modicon Quantum backplane, ensuring complete mechanical seating before securing retaining fasteners. Verify that the system power supply unit can adequately support the 2.5 A current requirement at 5 VDC alongside any adjacent communication modules. Both primary and redundant processors must maintain identical firmware versions to establish proper synchronization and prevent initialization faults.

Frequently Asked Questions

Q: What is the primary function of the integrated Ethernet port on the Schneider 140CPU67160?A: The onboard 100BASE-FX port provides dedicated Hot Standby fiber optic synchronization between redundant processor pairs alongside standard networking capabilities.

Q: Can this processor operate as a standalone unit without a redundant partner? A: Yes, the module can function as a high-performance standalone CPU within a single Quantum rack configuration, though its Hot Standby features are optimized for redundant architectures.
