Core Performance and Selection Advantages
The 140CPU67060 represents the high-availability tier of the Modicon Quantum platform, engineered for applications where unplanned downtime carries severe operational or safety consequences. Its dual-core architecture separates control execution from communication tasks, significantly reducing jitter and improving determinism compared to single-core predecessors like the 140CPU65160. With 4 MB of program and data memory—double that of mid-range CPUs—it accommodates complex logic, extensive HMI data blocks, and embedded historian functions without performance degradation.
Key functional highlights include native support for hot-standby redundancy without requiring additional synchronization modules, built-in Ethernet port supporting multiple protocols simultaneously (Modbus TCP, EtherNet/IP, and Schneider’s SRTP), and integrated cybersecurity features such as IP filtering, secure firmware updates, and audit logging compliant with IEC 62443. From a total cost of ownership (TCO) perspective, the 140CPU67060 reduces engineering effort by eliminating protocol gateways, simplifies spare parts inventory through platform standardization, and minimizes commissioning time via pre-validated redundancy templates in EcoStruxure Control Expert. These factors collectively lower both capital expenditure and lifecycle operational costs in large-scale deployments.

System Integration and Expandability
The 140CPU67060 is programmed exclusively within Schneider Electric’s EcoStruxure Control Expert (formerly Unity Pro), a unified engineering environment that supports multi-controller projects, version control, and seamless HMI integration with Vijeo Designer or AVEVA System Platform. This software ecosystem accelerates development through reusable function blocks, automatic I/O addressing, and built-in diagnostics.
For networking, the CPU natively communicates with SCADA systems via Modbus TCP and integrates directly into Rockwell-centric environments using EtherNet/IP implicit messaging. It also supports OPC UA server functionality (with optional license), enabling secure, standardized data exchange with MES and cloud analytics platforms. MQTT is not native but can be implemented via an external edge gateway (e.g., AVEVA Edge).
In terms of scalability, the 140CPU67060 supports up to 63 distributed I/O stations over fiber or copper (using 140NRP95400 or 140NOE771xx modules), allowing I/O to be placed kilometers from the controller. The system supports mixed I/O types—including discrete, analog, motion, and specialty modules—and allows online changes without stopping the application. Redundancy is fully integrated: two 140CPU67060 units synchronize program state, I/O images, and internal variables continuously, ensuring zero process interruption during failover. This makes it particularly suitable for water pumping stations, pipeline control, and power distribution networks where continuous operation is mandated by regulation or contract.
