GE Fanuc IC697CPX928-CD – High‑reliability CPU module for Series 90-70 PLC racks

The GE Fanuc IC697CPX928-CD is a high-performance CPU module designed for the Series 90-70 PLC platform. It drops straight into an IC697 rack, giving existing installations a dependable control brain without a control-cabinet redesign. One thing I appreciate is how it typically balances processing headroom with the rock-solid runtime behavior you expect in mature process plants—power, water, metals, and similar continuous operations.

Key Features

• Series 90-70 rack compatible – Installs in standard IC697 backplanes, typically occupying a single slot.
• -CD conformal-coating variant – Designed for higher humidity or dust-prone environments; helps extend board life in many cases.
• Deterministic PLC execution – Suited for batch, continuous, and discrete control where predictable scan cycles matter.
• Nonvolatile and battery-backed memory support – Retains critical logic and data across power cycles; helps during planned shutdowns.
• Front-port programming access – Typically supports programming/diagnostics via serial (SNP/SNPX) interface on the front panel.
• Long lifecycle support path – Often used in plants aiming to maintain validated processes while planning phased migrations.
• Field-proven reliability – From my experience, these CPUs run for years with minimal intervention when mounted and ventilated properly.

Related or Supporting Products

• IC697CHS750 / IC697CHS790 / IC697CHS780 – Standard 5-, 9-, and 12-slot Series 90-70 racks (select per I/O count and cabinet space).
• IC697PWR711 – Series 90-70 power supply; ensure adequate 5 VDC capacity for CPU + I/O load.
• IC697CMM742 – Ethernet/TCP-IP communications module for network connectivity (plant network integration, SCADA data paths).
• IC697MDL740 / IC697MDL940 – Discrete input/output modules; typical 24 VDC input and relay/solid-state output options.
• IC698CPE040 – PACSystems RX7i CPU often used as a migration path from 90-70; higher performance and modern firmware ecosystem.

You might notice that many plants keep a small stock of 90-70 CPUs and power supplies; a maintenance lead recently told me the IC697CPX928-CD has been “the least troublesome card in the rack” after they improved ventilation and replaced the battery on schedule.

Installation & Maintenance

• Cabinet and rack – Install in an IC697 rack mounted in a clean, dry enclosure meeting typical industrial cabinet standards (IP54+ recommended in dusty areas).
• Ventilation – Provide front-to-back airflow; avoid hot spots near the CPU. In most cases, 0–60°C ambient and stable humidity yield the best longevity.
• Grounding & wiring – Verify backplane ground bonding; keep serial/programming leads short and routed away from high-noise conductors.
• Battery & memory – Replace the CPU battery on the manufacturer’s interval to maintain retentive memory. Back up logic before maintenance.
• Firmware & tools – Use the recommended programming software version for your CPU revision. From my experience, matching firmware/tooling avoids nuisance faults.
• Routine cleaning – Lightly dust the module face and rack fans; for the -CD variant, avoid solvents that can degrade the conformal coating.

Quality & Certifications

• Designed for industrial environments; typically CE and UL recognized for Series 90-70 platform components.
• Manufactured under ISO 9001 quality systems (platform-level practice across GE industrial control lines).
• RoHS status varies by production date and region; the -CD variant often targets enhanced environmental robustness.
• Warranty: 365 days from delivery.

If you’re stabilizing an installed 90-70 line or planning a gradual migration, the IC697CPX928-CD usually hits that sweet spot—keep your existing I/O and wiring while restoring CPU reliability with a conformal-coated module.
