Application Scenarios:
At a major metropolitan water treatment facility in North America, aging control hardware caused weekly unscheduled outages during peak demand. After migrating to a dual-redundant 140CPU67260 system, the plant achieved 99.999% uptime over three years. During a live test where the primary 140CPU67260 was abruptly powered off, the standby unit assumed full control in just 35 milliseconds—so fast that chlorine dosing pumps never deviated from setpoint. This invisible continuity, combined with the module’s ability to manage 12.000+ I/O points across remote racks, transformed operational reliability and regulatory compliance. Today, the 140CPU67260 remains the trusted core of safety-critical infrastructure worldwide.

Technical Principles and Innovative Values:
Innovation Point 1: True Hot Standby Synchronization – The 140CPU67260 uses a dedicated high-speed synchronization link to mirror program execution state, data tables, and I/O images between primary and standby units in real time, ensuring zero process interruption during failover.
Innovation Point 2: Deterministic Multi-Tasking – With four independent task levels (including a 1 ms cyclic task), the 140CPU67260 prioritizes safety logic over HMI or data logging traffic, guaranteeing response consistency even under full load.
Innovation Point 3: Legacy Integration Mastery – Native support for Modbus, Modbus Plus, and RIO allows the 140CPU67260 to seamlessly integrate decades-old field devices while enabling modern Ethernet-based supervision—ideal for brownfield upgrades.
Innovation Point 4: Cyber-Resilient by Design – Built-in IP filtering, port lockdown, and secure firmware updates align with IEC 62443. protecting critical water or power assets without compromising openness.
Application Cases and Industry Value:
In a hydroelectric dam in Canada, two 140CPU67260 controllers manage turbine governors, spillway gates, and generator synchronization. The system’s 35 ms failover capability prevented a cascading grid instability event during a lightning-induced main CPU failure—earning recognition from the national grid operator. Similarly, at a Middle Eastern desalination plant, the 140CPU67260’s 32 MB RAM enabled integration of advanced anti-scaling algorithms that reduced membrane cleaning frequency by 40%, saving $ 1.2M annually in chemical and downtime costs.
