SCHNEIDER 140CPU67160

Description

The Schneider 140CPU67160 is a high-performance, redundant programmable automation controller (PAC) from the Modicon Quantum series, engineered for mission-critical applications demanding continuous availability and deterministic control. As the flagship CPU in Schneider Electric’s legacy yet widely deployed Quantum platform, it delivers robust processing power, hot-standby redundancy, and seamless integration with enterprise networks—making it a cornerstone of power, water, oil & gas, and heavy industrial automation systems worldwide.

At a major metropolitan water treatment facility in Australia, aging control hardware caused recurring unscheduled shutdowns during peak demand, risking regulatory non-compliance. The plant upgraded its core control system to dual Schneider 140CPU67160 units in hot-standby configuration. During a subsequent lightning-induced grid disturbance, the primary CPU failed—but the secondary took over in under 30 milliseconds, with zero interruption to chemical dosing or pump sequencing. Operators didn’t even notice the switchover. This incident validated why the 140CPU67160 remains the go-to solution for infrastructure where “always-on” isn’t optional—it’s essential.

Innovation Point 1: True Transparent Hot Standby

Unlike simple failover systems, the 140CPU67160 continuously synchronizes program execution, I/O states, and communication buffers between primary and secondary units via a dedicated sync link. This ensures zero process disruption—even mid-scan—during a failure, a critical requirement for pipeline pumping or power substation automation.

Innovation Point 2: Multi-Protocol Enterprise Integration

With native support for Modbus TCP, EtherNet/IP™, and legacy Modbus Plus, the 140CPU67160 bridges OT and IT worlds without gateways. It can simultaneously serve real-time control loops, feed historian data via OPC, and expose tags to MES—all over a single Ethernet port.

Innovation Point 3: Extended Lifecycle for Critical Infrastructure

Although part of the mature Quantum line, Schneider continues to support the 140CPU67160 under its long-term availability program, ensuring utilities and industrial plants can maintain operations well into the 2030s without forced migration.

Innovation Point 4: Cyber-Secure by Design

The module supports IP filtering, port lockdown, and secure firmware updates—features increasingly mandated in NERC CIP and ISO 27001-compliant environments. Its isolated communication channels prevent lateral movement in case of network intrusion.

A natural gas compressor station in Canada replaced its 1990s-era PLCs with a dual 140CPU67160 system to meet new pipeline safety regulations. The CPUs now manage 1.200+ I/O points across three compressor trains, with all safety interlocks executed deterministically. Thanks to built-in EtherNet/IP, the station integrates directly with the corporate asset management system—reducing manual reporting by 15 hours per week. Maintenance teams particularly value the Unity Pro diagnostic viewer, which pinpoints failed field devices within seconds. In another case, a hydroelectric dam in Brazil used the 140CPU67160’s Modbus Plus backbone to retain 20-year-old turbine governors while modernizing only the central logic—saving over $ 2M in capital costs.

Installation, Maintenance, and Full-Cycle Support

Installing the 140CPU67160 requires two identical units placed in separate Quantum chassis, connected via a dedicated 140CPS11420-powered backplane and a shielded sync cable (typically RG-6). Configuration is performed in Unity Pro using the “Hot Standby” template—ensuring automatic synchronization and heartbeat monitoring. During operation, front-panel LEDs indicate CPU role (Primary/Secondary), link status, and fault conditions. Routine maintenance involves checking sync link integrity and verifying backup program archives. Failed modules can be replaced without powering down the system, thanks to hot-swap support on compatible backplanes.

We source every 140CPU67160 through Schneider Electric’s authorized global distribution network. Each unit is new, factory sealed, and undergoes rigorous validation: hot-standby switchover timing (<30 ms), Ethernet/MB+ communication stress testing, and memory integrity checks. All units include original firmware and come with a 12-month warranty.
