Product Details

The Schneider 140CPU67060 Unity hot standby processor module is a high-reliability redundant dual-slot core control unit of Modicon Quantum PLC automation platform, designed for critical industrial applications requiring uninterrupted continuous operation and zero downtime. This modicon quantum cpu module adopts a 32-bit RISC processor running at 266MHz clock frequency, equipped with 512kB built-in RAM, and supports memory expansion via PCMCIA card up to 7168kB program memory and 8MB file storage. It is preloaded with Unity operating system and fully compatible with Unity Pro / EcoStruxure Control Expert software, supporting IEC61131-3 standard programming languages. The module is equipped with a dedicated multi-mode fiber optic hot standby link, used for real-time data synchronization between primary and standby CPUs. When the main CPU fails, the standby CPU can achieve bumpless automatic switchover to maintain continuous system operation. It integrates one 10/100Mbps Ethernet port, one Modbus serial port and one Modbus Plus communication port, supporting data exchange with local I/O modules, S908 remote I/O stations, distributed I/O stations, HMI touch screens and other field automation equipment. It can support up to 2 local racks, maximum 31 S908 remote I/O stations and 63 distributed I/O stations over Modbus Plus network. The onboard Ethernet port supports TCP/IP communication, web diagnostic function and Ethernet remote I/O scanning. The module comes with a 2×16 LCD backlight display and key switch for memory protection, supporting high-speed interrupt input, event time stamping and high-precision counter functions. A hardware watchdog timer continuously monitors program execution status and triggers safety protection actions automatically once abnormal operation occurs. It occupies two adjacent slots on Quantum backplane rack and must be paired with another identical 140CPU67060 module to build hot standby redundant system. This original Schneider product was discontinued on Jan 23,2021 and end-of-service on Dec 31,2026, widely stocked as spare replacement parts for maintenance and upgrade of legacy redundant industrial automation systems. It is widely deployed in power, petrochemical, natural gas pipeline, metallurgy, water treatment and manufacturing plants as the redundant core controller for critical Modicon Quantum automation racks.
