Product Role & System Fit
The IC695CMU310 is a central processing unit designed not just to control a PLC rack, but to provide redundancy and continuity within GE Fanuc’s RX3i automation ecosystem. Its role extends beyond traditional CPUs by supporting Max-ON hot-standby architectures, where two CPUs operate in tandem: one active and one ready to take over instantly if a fault is detected.
In an RX3i system, this module fits into a single slot in the universal backplane, communicating with I/O modules distributed across the rack and communicating over serial channels with external devices. Its physical footprint is engineered for compact backplane deployment, while internally it manages dual memory banks—battery-backed RAM and non-volatile flash—to ensure program integrity and data retention even through power transitions.
Integration with industry-standard expansion backplanes allows the IC695CMU310 to work seamlessly with both RX3i and legacy Series 90-30 modules. This backward compatibility offers a pragmatic path for phased upgrades: plants don’t need to scrap functional I/O racks when modernizing control logic hardware.
Because it includes two isolated serial ports (RS-232 and RS-485), the module also functions as a communication hub for field devices, SCADA links, and human-machine interfaces. Supported protocols such as Modbus RTU Slave and SNP make it versatile across hybrid automation networks where mixed hardware protocols remain common.
Operators and control engineers value this module not only for redundancy but also for its diagnostic transparency. Status LEDs and diagnostic registers help pinpoint hardware or communications issues early, allowing preventive maintenance and minimizing troubleshooting cycles. This blend of redundancy, compatibility, and communications flexibility makes the IC695CMU310 a strong fit in systems where uptime and integration flexibility are priorities.
