GE Fanuc IC697CPX935 – High‑performance CPU for Series 90‑70 Control Racks

The GE Fanuc IC697CPX935 is a high-end CPU module for the Series 90‑70 platform, used widely in heavy industry, utilities, and large process lines. From my experience, it’s chosen when plants need a fast scan, large application capacity, and long-term compatibility with existing IC697 I/O and networks. You might notice that it’s equally at home as a direct drop‑in replacement in aging racks or as part of a staged modernization where downtime has to be minimal.

Key Features

• Series 90‑70 CPU upgrade path – Ideal for brownfield replacements where the rack, power supply, and I/O stay in place.
• Fast logic execution – Designed for high‑throughput ladder and structured block execution; typically short scan times even on larger programs.
• Large application capacity – Supports substantial user memory with battery‑backed retention; expandable via 90‑70 memory modules in many cases.
• Built for tough environments – Industrial operating temperature range and robust backplane communication for big I/O counts.
• Flexible networking – Works with 90‑70 comm modules (Ethernet, Genius, PROFIBUS, serial) so you can match field needs without changing the CPU.
• Tooling compatibility – Typically supported by Proficy Machine Edition (Logic Developer – PLC) and legacy Logicmaster 90‑70, which helps during migrations.
• Event and fault handling – Solid diagnostics and fault tables ease troubleshooting; saves time during start‑ups and maintenance windows.

Installation & Maintenance

• Panel & cabinet – Mount the IC697 rack in a clean, ventilated cabinet. Maintain airflow; avoid heat sources. From my experience, keeping ambient under 50 °C greatly improves longevity.
• Rack position – Install the IC697CPX935 in the CPU-designated slot (typically slot 1). Ensure tight seating and correct keying.
• Power & grounding – Use an appropriate IC697PWR7xx power supply; bond the rack to a low‑impedance ground. Separate high‑voltage from low‑level signal wiring.
• Wiring & comms – For the front serial port, use shielded cable; follow SNP/SNPX wiring guides. Add Ethernet/Genius/PROFIBUS via the respective comm modules as needed.
• Firmware & software – Match CPU firmware with your Proficy or Logicmaster version. In many cases, a quick revision check avoids unexpected download errors.
• Battery maintenance – Replace the lithium battery (e.g., IC697ACC702) proactively every 2–3 years, or sooner in high‑temperature cabinets. Always back up the program before replacement.
• Routine checks – Review fault tables, scan time trends, and comms diagnostics during scheduled stops. Light dust cleaning on the module face helps connectors and DIP covers last longer.
• ESD safety – Handle modules with proper grounding. Power down the rack before insertion/removal unless the manual explicitly states otherwise.

Quality & Certifications

• CE and UL/cUL listings are typical for Series 90‑70 modules; CSA compliance is common on many revisions.
• RoHS status may vary by production date, as the Series 90‑70 family predates current directives in many cases.
• Each unit is covered by our 365‑day warranty; test documentation can be provided on request.
